My experience with batteries is in the golf cart industry, One things I like about lithium is the weight savings , any wheeled vehicle performs better if it weighs less, The other thing I like is the maintenance aspect, Most people don’t properly maintain their LA batteries , They either overfill them with water which causes a corrosion nightmare or they don’t fill them at all, Although I have to say Trojan batteries are quite resilient, one time I had a customer call and complain that their cart would barely move, when I got there I found that their 8 year old Trojan batteries were completely dry, the customer stated that nobody ever told them they had to put water in the batteries, l filled them to the proper levels with distilled water and the batteries lasted another 3 years.

The definition of marketing spin is an alternate reality or the art of confusion. What leaves me shaking my head is that it is taught at the University level and you can get a degree in it. You can become an academic truth stretcher. I worked for a branded food maker in their R&D department and they retailed in supermarkets. When we were developing a new product it was a constant battle to stop marketing trying to fudge the nutrition and ingredients panel and we would not always win. I hated making small-volume examples of our products in the Kitchen/Lab to send to them because I knew they were using them in the photo shoots for the advertising and packaging even though they were told not to. The product I made did not look like the mass-produced factory examples because that is impossible due to scaling issues in the mixing area. I also know that on a couple of occasions they had synthetic props made as they still did not like what the handmade products looked like. I was with them for 20 years; the worst marketing practices were in the last seven years or so. When you look at what is happening with the media and politics and many other facets of communication the truth is getting hidden, misrepresented, or even deleted far more frequently. I don't read advertising blurbs on anything as they are a waste of time.

Did the research 10 years ago and yes the lithium is better by a lot in every way for a price:) One thing that I don't like about lead acid is the blatant misleading AH rating. example, that Trojan 200ah batter will only give 200 amps at the 20 hour discharge rate, (so 10 amps an hour for 20 hours). You get far less than 200 amps at the 1 hour rate, (spec shows 100 amps capacity at 75 amp load). That 100ah lithium will give you about 100 amps for 1 hour at 100 amp load. That is a big deal when considering actual capacity at high discharge rate.

If you have to use batteries in an ongoing application, the cost of lead-acid batteries are actually higher, when you factor in the number of charge cycles before they wear out. Lead-acid batteries deliver power much less efficiently. They begin delivering less and less power from their first usage, and their performance drops off dramatically in a short period of time. Comparing Lead-acid to Lithium-Iron-Phospate batteries is a clear compromise in performance. And as stated, lead-acid batteries are actually more expensive in the long run. Lead-acid batteries would only make sense to me in a backup power application where they see little to no actual usage.

After three more years the same started to happen again, one by one cells would short out. When I asked for a replacement Brand T said no. I then studied more about the date codes on the batteries and they indicated a manufacturer date over 2 years prior to me receiving them. After much argument Brand T agreed to replace the bank a second time. Three more years pass and cells started shorting out. I was done with Brand T! I decided to buy some 2V traction batteries of non descript name at half the price of Brand T. They are still working more than 10 years later! The moral, buy batteries that have adequate space between the bottom of the electrodes and the bottom of the battery such that the inevitable build up of sludge doesn't short out the cell.

Especially the 100% constancy and the absorption time? Were they periodically equalized at high voltage as prescribed? Were they checked with the density meter to know if equalization or more absorption time was needed? Subsequently You chose heavy traction tubular plate looks. These cells withstand high DODs like cheap lifepo4. they can last over 2000 cycles all at 80% DOD. I do not think there are poor brands of these cells, as they are a niche market aimed exclusively at professionals.

If lead acid were outdated as many yuoutubers want you to believe, would the battery behems continue to produce them? The millionaire companies to use them for industrial traction or telecommunications? Lifepo4 are not superior at all...they are superior in many respects, but it always depends on the use. But only those who are really prepared in the battery technique understand this concept. Most users do not have the basis to understand the aspects and conditions where lead acid is superior. In addition, there are abyssal differences between the types of lead acid! An OPZV traction or stationary tubular plate battery or a planté battery, last 5 or 10 times a monobloc AGM. So saying lead acid doesn't mean anything. it's like saying lithium, there are many types of lithium with totally opposite characteristics. For example, lifepo4 is good in cyclic duration, but it is one of the worst lithium as a start-up capacity or discharge current. there are types of lithium that discharge at 10C..tried with a lifepo4 How many know that nickel-iron batteries have a life extremely longer than lifepo4? But until the youtubers command it, people ignore it. No one studies science anymore .. now we listen to show charlatans, as scientific authors.

Well said. I completely agree that the lithium is a superior battery but it really does depend on the use case. My RV goes on battery power a few days at a time only a few times a year. For the cost of a lithium I got a couple of nice lead-acid batteries and a couple of solar panels. If I was full time and boondocking regularly then lithium wins, but not in my current situation.

​@@sekainiheiwa3650 You might be thinking of the traditional lead-acid battery, primarily used to deliver a quick burst of power for starting the engine. The continuous energy supply to keep the car moving, however, is actually facilitated by the alternator. Deep cycle batteries, on the other hand, are specifically designed to handle deep discharge cycles. The video you're watching showcases flooded deep cycle batteries, which necessitate users to refill the electrolyte levels for maintenance. In contrast, sealed lead-acid batteries, also a type of deep cycle battery, require minimal upkeep and are spill-proof. In terms of construction, deep cycle batteries boast thicker lead plates compared to their traditional counterparts. This design allows them to provide sustained electricity over longer periods, although they deliver less instantaneous power compared to traditional batteries.

On the side by side comparison they are also unfair when comparing a 100 Ah lithium to a 200 Ah lead acid battery. That pushes the weight and cost of the lead acid up higher to start off with. Also a lithium battery benefits from not being deeply discharged and fully charged every cycle. The cost over 10 years is incorrect as well. If you go with their original number of 50% dod, lead acid batteries can last 10 years and longer. My Trojan T105s are about 10 years old and still going strong in a solar power environment. One more thing that limits Lithium batteries in RV and off grid solar use is the need for external control circuitry for lithium batteries. I am slowly replacing all my lead acid batteries with lithium. But the supporting electronics are way more expensive and complex than for lead acid batteries. But again, I am gentle cycling my batteries so my electronics are more complex in the first place. And one more final point. For years I have slept peacefully with lead acid batteries in my RV or home. But with lithium there is always that fear of an explosion or fire. Just this morning I found a portable power bank overheating on charge and took it outside for safety.

It would also be interesting to bring up the ability to charge in cold temperatures, and the ability to withstand long periods at 100% charge in 100+ f temps without damage/reduction of capacity.

That said, for a boat where extreme temps usually aren’t an issue, or for a residence or full-time RV that will always have climate control (furnace or AC), lithium would be a no-brainer. For an occasional use RV, though, either battery type is likely to degrade due to age before hitting max cycles, lead acid preference to be stored at 100% is an advantage, as is its cost, and temperature tolerance.

Biggest issues with AGMs on solar systems is the fact that they follow the peukert’s law and that they take forever to float charge. They need at least 40 hours of float charging, which doesn’t work well with earth’s 24-hour day. On the contrary, lithium don’t care what the discharge rate is, plus they can easily cope charging to 100% in a few hours.

A friend of mine in the battery business once said “There are lies, damn lies, and battery salesmen”. i’ve been using vmaxtanks lead acid deep cycle batteries in a solar back up system.

My main reason is the weight and size as I take the batteries in a pack on my back. The energy density is much better. As far as the 50% depth of discharge for lead acid, as you stated, it generally reduces the life of the battery. So much not to like about lead acid is the off gassing. I've had lead acid and sla swell, where the lithium iron hasn't for me.

It seems that most commenters are using lead acid for power backup. In terms of weight or even volume it is not nearly as critical when the application is non-mobile. In the non-mobile application, the strategy would be an incredibly oversized bank of batteries be it lithium or lead acid. If the capacity is multiple times larger than the momentary need the power in and out can be better managed when the battery is greatly oversized. Thus, sparing the potential degradation that would occur on any battery bank and extending the time (range, number of hours) it could run your home or facility. The ability to absorb alternative energy in real time can be managed better by size as opposed to performance. Even though you have limited charging speed it is just a matter of creating a bank large enough to absorb high current.

I can neither confirm nor deny. And I can't fault anyone for buying a cheap Grade B battery. For most applications and financial scenarios they are great. But where I have a problem is manufacturers not telling you what you are buying OR outright deceiving people into thinking they are Grade A when they are not.

For me I find lithium is not worth it for a number of reason. Mainly because I camp mostly in the off season when the temps are low around here. Yes lithium have a BMS to prevent operation when temps are outside of the safe range BUT this still does not stop the fact that in extreme cold they will not work (not able to charge so no power to draw from). My AGM will still work. Lower capacity and with other issues BUT in 18 years of temps as low as -50c my AGM's have worked for what I needed them for. I keep my AGM's installed 12 months of the year in all temps with no issues. The other point I always laugh at is people that promote the weight difference. YES lithium are lighter BUT in a home (why do you care about what they weigh) or in a 40' class A (that weighs as much as a house) the weight is not a factor. Even in my Ford Transit the weight savings are there (200lbs as I run dual batteries) but I carry so much other stuff that it is a VERY small percentage of the overall weight. PLUS in the winter I carry extra weight for traction anyhow. Maybe I should tell my passengers that they need to diet before getting in or only let skinny people ride with me. I see so many vans and buses that promote lithium (mostly as they are sponsored) then do their build with 1/2 or 3/4" plywood, ceramic tiles, marble counters - this all adds more weight then you saved with the lighter batteries. If I lived someplace else I probably would go with Lithium but not here and now!

I run three combine harvester batteries with a solar panel that gives 8 amps when sunny they power a 3000wat inverter modified sine wave it runs a 1200 wat microwave for 40 min boils 6 kettles of water it keeps the caravan battery charged up to, in the morning the batteries still have 85% this is over 3 years now, paid £475 for the three batteries in total rated at 200 amps each , very pleased with this set up, the only bug I have is I wished the inverter was a pure sine wave type, as you said it’s what you need the task to be for the batteries lithium ones would have been far to costly, and easy to run off with if stolen it would take a grizzly bear to hump them combine batteries off lol 👍

The ideal for lead acid is keeping them between 75% and 95% charge. The ideal for Lithium is 30% to 80%.

Good points made. Especially since I want to choose my system components individually, I really need to learn the important differences of what's available.

By your own numbers you're not going to get 5 years at 100% depth of discharge out of the Trojan, closer to 2 and it's not going to be covered under warranty. So their 10 year pricing estimate is pretty close, you can replace it 5x at 100% DoD or 3x at 80% DoD or 2x at 50% DoD. Any way you slice it the 10 year cost of lead acid for a given usable Wh capacity is going to be significantly higher than your chart shows.

Interstate 105ah 6v batteries at Costco run around $100 (they were ~80 when I purchased 4 of them 6 years ago). We do a lot of dry camping and they are still running strong. We can go 4 days before they drop below 12v and need to be recharged. When they do need to be replaced we will probably get the LiFePo4. The trailer has an isolate switch and even 5% discharge seems high - they don't loose 30% charge over the winter.

My 2 volt lead acid batteries are 25 years old and still work fine

I use SOK Lithium batteries and live in the Caribbean. The batteries are 12.8v *100ah at a base cost of around US$570, about 57% of the cost of the brand you used in this review. Many popular/good brands of LiFeP04 are sold well under US$500 online. Battery weight is a very important factor that impacts the final price as the cost of moving freight particularly in times of rising fuel cost simply cannot be ignored. I have used so called deep cycle lead/acid batteries before from another brand and they failed miserably when deep discharged. After almost three years I have not had this with my LiFePo4 batteries. I think this review could be very misleading to persons who truly want to make an informed decision.

From the comments I see people didn't really get the point of this video. The point is, as far as I see, that you should not use the comparison table of a company selling Lithium batteries to find out which chemistry is better for your application and if it worth the money - because they tend to tweak it to sell their own battery whatever the truth is. Also, I don't think it makes sense to compare two batteries. One should compare the total system cost and behavior of a specific application with the two kinds of batteries and then decide. And all the superior qualities come with "just higher upfront cost" but exactly that puts it out of reach for a lot of applications for which you just don't spend that kind of money. For the price comparison: yes you can get lots of LiPo under 500, but then you will also not compare it to a Trojan but pick one from the middle range. Price diff will be similar. In these comments there are a bunch of cases where people went Lithium and were happy. There are also a lot of cases where people use Lead-acid for a fraction of the cost and it works out for them. One can't just say "which one is better" in general.

I was just saying the same thing to my wife the other day. They are lying to everyone about lead acid batterys I'd much rather have the heavyweight leadacid anyday good video my man 👍

I still like AGM because the voltage curve lets me set up low-voltage cut-off devices for downstream appliances based on particular voltage reflecting DOD (remaining capacity). I can't do that simply and cheaply with lithium because the voltage curve with respect to capacity is largely flat, except a the extreme ends, say within 5% of fully charged and fully discharged. With lead-acid I can pick voltage points to suit the priority of loads to cut off. I like that for some installations. There's no doubt LiFePO4 is great technology, and it does comes with an up front cost premium, but depending on the installation and the scenario for use, it may well prove more costs effective compared to AGM or other lead acid batteries over the long term. It really comes down to having accurate specifications and prices, accurate design criteria for intended use, and the correct methodology for the individual doing those calculations to work out what's best (initial price, ongoing costs, weight, lifespan, redundancy, maintenance, etc) for the end user and their budget. It begins with having the right information to start with, and if companies keep putting out information like you've shown, it's no wonder people get themselves in a tangle, or at least form an opinion that's not based much in reality, but based on marketing spin. I always look forward to your videos. Cheers, from Australia.

@@TheSiprianus Hahaha...when you say it like that, it just sounds silly ;-) No, I'm not choosing 'easy to read capacity based on voltage' over a 'voltage stability for safe, consistent, and overall better performance' for clients with respect to battery chemistry choice. Rather, if the battery criteria for a client ends ups being a lead-acid of some variety, the lead acid 'voltage vs capacity' curve has a characteristic that can be used to switch load thresholds on and off relatively easily. Or put another way, it's something that's there and can be used, if people want to, and if appropriate. LiFePO4 will show only about 0.2-0.3V range over 70-80% of capacity range, and while that's a good thing overall, it's way too tight for most devices using voltage thresholds to switch loads on or off. AGM will show about 1.2-1.4V for the same 70-80%, so that's quite generous. Yes, high current draw will create a voltage drop giving a false reading of the true state of battery capacity at that particular moment when using 'voltage vs capacity' curve thresholds. I don't use if for this. Most low-voltage cut-off devices have a bit of hysteresis built into them, helping alleviate that a little, but it's not a perfect solution. I'm really using these low-voltage cut-off devices to safeguard batteries from over discharge, not to determine how much capacity is left, but that is the de-facto relationship of this method. A cheap battery meter will not automatically disconnect non-critical loads that can be shed when needed, and battery meters that have this feature are not cheap (Victron BMV-712 for instance AUD350.00 versus Kemo Battery Guard AUD45.00). Many budget battery meters (watt-hour or power meters) will display capacity in Ah or Wh as charging and discharging occur, providing a real-time indication of capacity remaining, but few cheap ones have any ability to disconnect loads at at particular Ah or Wh threshold. If you know of an inexpensive unit that does this, I'd be interested. Some of these meters will have low- and high-voltage cut out, high current cut out, over temperature cut out, but no user configuration cut out for power used to a particular power level. A typical AGM installation for vehicle/camper might be a low-voltage disconnect with alarm for the system, set to 11.6-11.8V. All loads go through this device. Non-critical loads go through another low-voltage disconnect set for 12.2-12.3V and will reconnect around 13.0V. This effectively means they will not come back on again unless the batteries are being charged. I set the thresholds using a bench power supply to get them to where I'd like. During commission of the system a watt-hour meter used (unless there's one in the system already) to determine approximately what capacity is used at those thresholds, and make any adjustments if necessary (which is a tomorrow job, since I have to recharge the battery again overnight).

So it produces a service event for stealerships to keep people coming back for a repair every two years. After going through 3 lead acid batteries in my EV in six years, I put a LFE starting battery in my Merc B class EV and it is working much better.

An unrelated question for you JoAnn, this week gone I had to purchase several UPS units for Lab equipment and was amazed at how few of the units on the market have pure sine wave output. Given that they are a devise designed and supplied to "allow a safe and orderly shut down of a computer and associated equipment in the event of a power supply problem". My understanding was that a computer should only ever be run on pure sine wave. Should the UPS power protection industry be regulated.

One of the big problems with the lead acid battery is if it is discharged for a certain period of time it will degrade the battery so it is a problem with the solar if it cannot get a charge due to bad weather..

This is like comparing a screwdriver to a voltmeter they have different functions think of lead acid as a heavy powerful weight lifter with no stamina and a long recovery time and Lipo4 as a lightweight long distance runner with quick recovery. There is a review of both on our channel used with trolling motor, induction cook top and cargo conversion trailer if you are interested

my choice was automatic for me. My restrictive income can only afford AGM lead acid. The 12V 100 AH just under 200.00 a lithium of the same size close to 400.00.

I don't use any lead-acid batteries (well, other than in my cars), but if you are strictly off-grid, and PV is so inexpensive relatively speaking, that doing a proper setup with a significant oversized PV array so that you can top charge your battery at the efficient slower charge rates for lead-acid every day, there is still a strong case for it. Also, if you just want a system for backup power on an occasional basis but otherwise float the battery, there's not really a reason to spend more for lithium unless you need the weight/size reduction. I personally use lithium batteries because I make minimal setups where batteries end up spending long times at a partial state of charge with opportunistic charging in between use.

Lithium has two advantages. Weight.. Can be mounted inside the vehicle... One draw back of Lithium.. If it catches fire. Just move away. It's burning your RV to the ground. As not even fire fighters will try and put it out...They just watch it burn...

There are at least two very different Li battery chemistries: Li-ion, or NMC, and LiFePO4, or LFP. The former has a shorter cycle life than LFP, so I'm assuming your chart is using stats for LFP. Even then it depends upon how the battery is packaged (compression, for one thing with LFP). One of the markets you cite DOES cycle their batteries every day, or even multiple times a day (e.g., golf carts, perhaps not 100% on every cycle). There are other applications, like industrial forklifts and trucks, that likely do as well. There are safety implications. The NMC Li chemistry uses an electrolyte that combusts when exposed to air, while the LFP does not. Lead acid gives off combustible hydrogen gas during charging, unless it's a sealed cell design. But since there's no claim on the marketing chart, I guess that falls into the other considerations list.

Love this. I was really swinging to the lithium but I decided to purchase 4 150ah agm sun batteries @120lb weight made in Germany £900 got discount and so far they have definitely been good batteries Very early days But they say they should last 10 years + if they do ile be happy

The recharge time on a lithium is literally 1/4 the time of the l and acid. Also, capacity drops off radically on a lead acid battery as it discharges. In 30 degree weather it's only about 1/3 the capacity of lithium. Lead acid batteries fail on every comparison. The cost over time for a lithium battery is dramatically less than l and acid also. This is also besides the weight and size.

Excellent information on the two. I wouldn't mine Lithium, but there are a few reasons why I won't get them; for now! 1) cost, 2) Ah capacity. Lithium would be excellent, but until they can be at least 375Ah plus cost close to leads. Today if you look at the weight of the " B-B Game changer, " the weight is over 80lbs+, and that's at 270Ah you need another 100Ah at 31lbs+; so, 111lbs X 4 = 444 lbs total, then add the room for 4 270Ah + 4 more 100Ah batteries is a factor, for sure. Let us say four 375Ah Flooded from East Penn/ Deka at 125lbs each x 4 = 500lbs. So at that kind of weight, it doesn't really matter, at 60 lbs. Then the room/ area to hold them, I bet I can put East Penn flooded in the space of 3 feet x 2 feet at about $1400.00. The cost for the Lithium of somewhat the same Ah would be about $14,000.00 upfront. That's a chunk of change. If you don't mind, the monthly maintenance on flooded.

Your quote of $14,000 could buy a whopping 1,800 amp/hrs worth of the EG4 server rack batteries, so I must be missing something,. because the numbers are way off.

I had an AGM battery on my motorcycle for 11 years until it finally gave up, I replaced it with a lithium battery a decent quality one, cost as much as the AGM battery did at the time, it lasted just under 4 years, replaced it with another lithium half the price thinking lithium batteries had fallen, it lasted just over 1 year and was a terrible battery.

You could get the deep cycle batteries instead of the AGM for depending on the you can get from 106 to 122 amp hour battery for from $80-122 each last month we replaced our battery pack with 5-122 amp hour batters that’s 610 amp hours for $540.00 at Walmart they said that these are the most popular batteries that people around here are using for there solar. AGM are half of the power as these and there are still people trying to use 6 volt golf cart batterers at $600 for 100 amp hour and you need 2 just to get 12 volts you have to special order them because the manufacturers have been trying to stop making them since the 1970’s but the smart people won’t stop trying to use them.

I tried to get the materials to make my own batteries because my friend wouldn’t part with any of his but it turns out that you can’t put it here you have to order it from China they will build it there and send it to you but they don’t want to build you batteries that won’t ware out you can either get lead acid or one of the lithium types around 15 years ago they were having a big push in third world countries using nickel iron batteries and solar panels they put a stop to that

You won't find one. All you will find is opinions. There are too many variables and too much of "value" is tied into consumer preferences. Some might find value in a 20 year investment with high upfront cost but a strong 10% return on investment, similar to the stock market. Others may find value in lower up front investment, less "fuss" (like rewiring a boat or RV), and less risk. But if you are strictly speaking of value in terms of dollars and cents, it remains to be seen how long these lithium batteries will really hold up. Grade A cells are rated for 3,000+ cycles, but will the BMS last that long? Will the internal wiring and connections last that long? There isn't a single lithium battery company that has been in business for more than 12-13 years, that I am aware of, so it isn't possible to know for sure. MTBF ratings and lab testing can only take us so far. All I can do is help to fact check the marketers and leave it up to you to decide. If you are looking for someone to tell you how you spend your money, there are plenty of other KZreadrs for that.

The lithium battery may be assembled in the United States but all the parts (the cells, the BMS, and probably the plastic box) are all coming from China. Saying that they are manufactured in the US is disingenuous at best.

I am a small solar experimenter. I get used sealed 7.2ah lead/acid from UPSs abt. 2-3 yrs old. They work fine for me in my two small systems running mostly lights and charging small stuff. One battery bank is charged by an MPPT controller and the other by a PWM controller. Both fully charge each battery bank by early afternoon each day (unless its rainy or overcast) I will soon buy a small Lithium battery and either run a third system or just replace one bank with the single Lithium battery. Greetings from Jamaica where its summer all year round.

Lithium is great if you need the energy density (I.E. Size is important), but are far less compelling if energy density isn't an issue. I think that for most people, Lead Acid make better batteries for solar installations (assuming you have the extra space) simply because you can generally get 100% more capacity for about 85% of the price of a lithium (at least in South Africa). Double the capacity means that I can discharge less than I would otherwise need to (extending the life of my batteries significantly), but it also means that in an emergency I have more charge. I wish that someone would create a commercial battery management system for Lead Acid batteries, which would make charging and discharging safer, but more importantly, would make it simple to ADD lead acid batteries to an existing installation rather than having to REPLACE the older batteries, which is currently a huge benefit to LiX over Lead Acid - and that benefit is all in the BMS and nothing to do with the chemistry.

Have to agree. There is really no need to exaggerate. On the whole, in most applications, mainly portable power systems, Lithium wins every time. Yes, good quality lead acid batteries are still good batteries, my liveaboard boat came with them (AGM), but their intrinsic performance qualities left much to be desired.(Most aggravating was voltage drop) After switching to Prismatic LifePo batteries life has been much more pleasant. Granted my perfectly adequate charging system for LA batteries is now woefully underpowered and slow, but it does keep up. The extra expense up front has been well worth it, in my humble opinion. The maintenance thing is true. I hardly ever even look at the new batteries. I monitor individual cell and overall pack voltages and use a SOC monitor to track general health. All my 12 volt stuff love the higher voltage levels, especially high draw items (think refrigeration and cooking) and the additional useable capacity makes extended periods of none charging days much less stressful. (I use solar charging, mostly, backed up by suitcase gas generator). I could go on and on addressing each category of comparison, but I think you get the point. Never going back to lead acid.

Lithium battery exaggeration goes hand in hand with EV range exaggeration, which ultimately comes back to the lies told by the lithium battery manufacturers. I have yet to see a lithium battery lives up to the promises they make.

10 yrs back when I built my first RE system Lithium were new & expensive so I opted for FLA 48V 1000Ah (x24 2V forklift cells in series) and to my surprise they are still going now having cycled daily to around 80% SOC and never below 50%. Here in Europe the cost of LFP 300Ah cells is finally comparable I can make a 45KW setup (3x 16S cells + BMS) for roughly the same cost as another 48KW FLA battery (which is now double what I paid in 2014). If the hype is true I would expect to get 15-20 yrs from an LFP if cycled 30-70% SOC with occasional balance charge to 100% so I'm looking forward to using a different chemistry. The hype on Lithium is outrageous here too the Chinese claim 10,000 cycles @ 90% DOD which is baloney for sure. Thanks for keeping it real.

@LDSreliance

Yes, please take the marketing info from all companies with a grain of salt. The jury is still out on exactly how long these mass produced LFP cells will last. When I started selling them in 2017, the claim was 3,000 cycles @ 100% DoD @ 1C for a Grade A cell. Now all of those same companies are claiming 4,000-4,500 plus but no one can tell me why. I have never been able to find any new technological breakthroughs or improved manufacturing techniques or anything that substantiates those claims. And obviously no one has had any of these batteries for 20+ years to fully use that many cycles, nor are manufacturers actually fully cycling them to 100% DoD that many times. This is all based on estimates and projections. The only remaining explanation is a marketing arms race where everyone is trying to outdo each other in their marketing and specs hype and the customer has no way to disprove or dispute such a number. I don't like that but what I really don't like is the blatant lying on the Grade B stuff. There will never be a Grade B battery on planet Earth that will perform exactly the same or last fully as long as a Grade A battery. It just can't happen. It doesn't matter if you top balance the cells manually or have the best BMS on the market or all of the Grade B cells are closely matched from the same manufacturing run. They are inferior and that is why they cost 1/10 or less in comparison.

Sounds like your detector is well tuned. Keep researching and learning and find a company that you are confident will stand by their product. At the end of the day, that is going to be the best bet on the best experience.

The caveats with LA are it must be charged as soon as it's discharge cycle has finished due to sulfation, it must have a topping off charge which runs into hours, it must receive a minimum bulk charge current when deeply discharged and requires a float charge when fully charged. These are great get-out clauses for warranty. Only really UPS installation companies and car's can properly fullfil these criteria. For solar off grid systems, lithium is a huge advantage. I spent years fretting and maintaining my LA off grid system, I switched to lithium and my worries have, er, changed somewhat lol. I no longer worry about soc or dod. I now worry about BMS failure and possible fire..... But I do love my lithium ion batteries. Well worth the expenditure.

Appreciating what your saying here, you leave out a big elements on 'like for like' comparisons - like charge efficiency. LA looses as much as 1/4 at higher rates (ie discharging it overnight), lithium virtually nothing. that means the trojan here is more like a 150ah battery at high rates, not 200. Some other important bits on warranty too: - they have a max DOD stipulation of 50% - so there's no warranty at all in your 100% DOD comparison here. Also 'justifies' the 50% capacity use in the original comparison - They have a 'delivery' clause (ie only has to deliver 50% of its rated capacity to not be defective (unclear if this compounds with above) - They have a temperature clause of 50% warranty reduction for every 10C above 27C... pretty drastically low... ive seen lithium ones that only start limiting above 60C. - the warranty is also pro-rated (though this is common on lithium too) so by year 4 your down to 20% max return on warranty, vs 60% for lithium (all else being equal) IE, your kind of replacing a apples to oranges comparison, with a oranges to apples comparison.

To me, the main thing is LCOS. (Levelized Cost Of Storage). If the Lead Acid lasts 1/2 as long, but costs less than 1/2 as much, Lead Acid may be the better deal. It's very easy to add the extra few solar panels, to pick up the difference in efficiency, because now days, photovoltaic panels can be had for less than $1.00 per watt. For solar, the big advantage of lithium, is its tolerance for being maintained in a partial state of discharge. Lead Acid batteries MUST be fully charged regularly, to prevent a condition called "sulfation". That means a much lower overall efficiency. A lead Acid battery is really quite efficient in its 'bulk charge' region, but, use up a lot of excess energy for their 'absorption charge' region. This is an easy thing to deal with, but, you must oversize your photovoltaic system by at least 20%, to have enough excess, to properly maintain your Lead Acid battery system. My primary interest, is off grid renewable energy, mainly solar, but, wind if practical. In the event that these are not enough, or the storm that knocks out the grid also dumps a foot of snow on the panels, I can use a large generator. If using a generator, I recommend using it to bulk charge the Lead Acid battery, rather than wasting fuel for the absorption charge, which means running the engine for a long time, under light load. Wait for the sun to come up, or the grid to come back, for that absorption charging.

I use two 60dollar 18ah SLA batteries in parallel for 24 volts as a power backup, with converter, and RV power setup for my CPAP machine. I leave batteries on charge with a battery minder. I use the same two 18ah SLA batteries in my mobility scooter box. The only problem is the two 18ah SLA batteries are like carrying an anvil. Two 18ah Lithium batteries would be about 1/2 as heavy and give better duration/mileage but at considerably higher cost. Accurate lithium battery "remaining charge" meters are becoming available for mobility scooters.

one more thing is that if you are buying two lead acid batteries buy them at the same time and connect them in parallel then only discharge them to 50% capacity this would extend their cycle life.

Just purchased 32 brand new Interstate GC2 6 volt 225 ah batteries for a system I'm putting in my shop for roughly $5k. This included all core charges and taxes. While I recognize that the Lithium chemistry is superior, I didn't have $20,000 cash laying around that I wanted to spend on lithium. I've been working with these things in heavy equipment for years and seen them routinely last 3-4 years under the most grotesque conditions imaginable. I believe that I can get 8 years with a little maintenance. In addition, I don't have to worry about the fact that the shop gets over 100 degrees f in the summer and near zero in the winter. As the pack ages, I'll be able to replace defective batteries with refurbished batteries for $45 each. No core charge since I'll be swapping out my batteries. These batteries are almost 100 percent recyclable...no landfill waste. We have a vast infrastructure built out in this country to build and recycle these things...no crazy global supply chain to deal with.

Agreed. Just keep in mind for solar you need to make sure that you are not short cycling those batteries. In heavy equipment with L16 batteries or similar, they are designed to be thrown on a charger overnight and fully charged before being used again. In solar systems, that may not happen unless you design the system with enough solar to pull off a complete charge before the battery bank is called on to provide any power again. That requires an almost over-large solar panel array for the application.

I completely agree with your closing line: do your homework! One thing one could point out: battery protection system. You don't need one on a lead acid battery, so claiming to be a plus for brand X is misleading again.

I use cheap AGM's, solar controllers and AC chargers and discharge to about 50% or less when in use in my campervan. I have so much solar capacity on the roof my batteries rarely get touched. I park under trees when it's hot and use a 30'' extension cable to a 250W stowable panel that's in full sunlight. My whole setup, excluding panels, would be under $250 including the battery, both chargers and monitoring electronics. I would never go to Lithium until they drop to the current price of AGM's. Everything is still geared towards AGM's.

Horses for courses. I have a trailer (caravan for your Brits) and still using the lead acid batteries because we don't go off the grid for more than one night now and then. Cannot justify the cost of lithium there. My boat has a large battery set. Still using marine lead/acid batteries here for the same reason. Might anchor out for the night but will run the engines the next day and recharge. The markedly lower cost lead/acid battery set lasts 5+ years for me. Lithium would be roughly $2,000 to replace the house battery set (not the engine battery) Cheaper in the long run? (maybe - not sure) My plane is a no-deal for lithium. The FAA will not even discuss putting a lithium in it. For our tractors and combines on the farm, lithium can't handle the cranking amperage on a cold morning unless it is maybe 4000+ aH or bigger. Those numbers don't pencil out.. But, I do use Lithium for portable use in my ham radios and my astronomy observatory. Lithium for walky-talky./ phones Lithium for flash lights, search lamps, etc. Nothing comes close to convenience and performance and ability to keep on working in the wee hours.

You can increase the number of cycles of a lead acid battery if you only discharge to 70 or 60 percent quite a lot. I am not confident that lithium lasts as long as manufacturers claim and think there could be a lot of disappointed people in the decades ahead.

And if you check the fine print on those spec sheets (if the manufacturer discloses the info at all), you will usually see that they rate their claims of 4,000-7,000 cycles or whatever at 0.2C. So, sure, if you baby that lithium battery and never make it work very hard it might last a million years. But these people are buying these batteries for their boats and RVs and golf carts. They get put to a lot more of a load than 0.2C and then you will end up, like you said, with a lot of upset customers in 6-8 years when these batteries start failing or having obvious capacity loss because these people were mislead.

An excellent video. The only thing I would point out though, at the 7:00 mark, the fact that lead acid batteries do not NEED any electronics is clearly an advantage in favor of lead acid. Electronics in general are failure prone, and you cannot have an electronics failure if you do not have any electronics. The dependence on electronics for the safe and reliable operation of lithium batteries is the only thing I do not like about them. I REALLY wish they could work simply and reliably WITHOUT electronics of any kind, besides perhaps an energy monitor to keep track of state of charge. If it weren't for the weight difference, I would definitely be putting together a lead acid battery for my bus conversion. And I still just might! The bus can certainly carry the extra weight...

Depends on your preference. The battery will last longer as far as cycles, but you get a proportionally less amount of power each cycle. So it balances out. The total energy stored and discharged would be pretty close to equal whether you discharged it to 0% every day for x years or 50% for y years. However, over a longer lifetime there is a slightly increased chance that the BMS or other part of the battery would fail before the cells do and the cells are the ones that are rated for cycle life, not the entire package.

I live full time in my RV so I absolutely do cycle my batteries every day, sometimes even more than that.

I’m 100 percent pro lithium but in a large emp blast don’t think the bms would survive where lead acid wouldn’t even new anything happened plus if I was stranded in the middle of nowhere no tool nothing can only have one battery would choose lead acid

Put the battery in a box with at least aluminum foil thickness of metal it will survive. The balance leads are the sensitive ones not the power side and most of the device looks pretty shielded.

loved this video I'm still glad I brought 6 AGM batteries for my solar system I feel lithium is still too expensive as the 6 block AGMs only cost me £1400 and are 150ah each If I'd brought 6 lithium that would of been closer to £3000 for what I needed

Awesome! Welcome aboard!

The only downside to Lithium batteries is the potential for them to explode or catch fire. I would never stack them inside my house for my solar. I'd be building a fire proof locker outside most definitely.

What I didn't know before buying a lithium battery, is cold weather factor. As I understand it and have read numerous places, agm batteries handle colder weather better. This is a pretty big factor in what I buy. While I agree lithium tends to have more cycles, but in all honesty, where I live (Missouri) it can get pretty cold and have some pretty harsh winter days. Being that I leave my batteries in my van and it being pretty cold in winter, in my case I would fair better with a agm battery as apposed to lithium because of this factor. Now, if I lived say in Arizona or California or maybe Florida, lithium would be the better choice, but I don't so agm is the better buy in my case, considering I don't have heat when at work like say an RV would to keep the batteries warmer. Honestly there are some things that are relative, because it depends on multiple things you have to factor in when buying a battery, just like when buying panels, it really depends on how you use it, what is hooked up, the place you live, hour much sunlight will you get, etc.....

Lithium also does not like hot days. Or cold days.
