Very well done. I had my lithium’s shut down on me last year and wouldn’t take charge. Did the same thing as described with another battery and woke up the charger. Great questions and a great report. Keep up the good work

082220/1628pst. That was the most intelligent discussion, educational even. The presentation was not scripted, the two people exchanged views and comments that came out quite naturally, which is very commendable. The gentleman in yellow Jacket explained well to the other gentleman, who was quite inquisitive to understand the intricacies of flooded Pb cell batteries and the LiFePo4 batteries, or the comparison between the two. I have yet to come across such intelligent program in YT in my life. No comments on “ others!” You know what I mean ! Thank you, both of you. My respects and 73s...

Amazing video Andrew! Easy to understand and great information for all of us. I've been dying to get hold of a Lithium Battery in Malaysia but can't find one. Keep up the great work you are doing for the 4x4/overlanding community!!

This was a really helpful video. especially the last part about when you run a AGM or SLA off an inverter, compared to a Lithium battery.

Good informative video on lithium battery purchase breakdown. Thank you both for discussing this topic for us uninitiated campers !

Fantastic video. Answered a lot of questions. Very well presented. Great stuff!!

Great video Andrew. Heiner (sorry if I misspelt his name) is fantastic at giving clear explanations of the technology and the function of the batteries. You both did a great job. Really enjoyed it and feel much more confident about the value and limitations of lithium batteries. Thanks lads.

Extremely informative, thank you!

Great video Andrew and Heiner, thank you.👍

I'm afraid I have to disagree with the prismatic being better. Especially in an off road scenario. Cylindrical cells are wound tightly and encased in a metal casing, This minimizes electrode material from breaking up from mechanical vibrations, thermal cycling from charging and mechanical expansion. The complete opposite to prismatic construction ! Remember those Optima glass matt super tough off road starter batteries from the 90s? No coincidence each cell was constructed in a cylindrical manner.

O man I have been watching so many videos on lithium batteries but this has put it in a way I could understand. Thanks so much. Brilliant.

Very unclear definition as there are several DIFFERENT Lithium battery technologies. Main known ones are LiPo and LiFePo. The former is used in phones, Electric cars etc as it has higher energy density. But also the known ,explosive fire, variety. It use allows smallest size for given energy capacity. The storage battery presented is LiFePo variety, where the far more stable, less fire prone technology is better, at small loss of energy capacity for given volume is of no concern. But for clarity this presentation should not refer to just 'Lithium' battery but state the technology specifics. Even the optimal charging is affected by Lithium technolgy used.

We just upgraded from AGM's to Lithiums by building our own battery bank on our sailboat (we liveaboard) using 180 amp hour, 3.6-volt CALB cells, and a DALY BMS, wiring the cells in a 4s2p orientation. So stoked on the upgrade! We charge our lithiums in 2 different ways. We send the power from our 120 amp Balmar alternator on our engine to our 100 amp-hour sealed lead-acid starter battery. From there a Renogy 60 amp DC-DC charger takes the load from the alternator and puts it in a lithium profile and in turn charges the lithium batteries. It was a fun build!

As someone that's trying to get a rig put together, and looking at the differences between these two batteries I really appreciate all this information, especially about how bad of an idea it is to put a lithium battery under the hood. Tons of great information here, thank you! I'll have to check out more of your video's. :D

Lovely, very good help. And learned a whole lot. Thank you. And more power.

Very entertaining and informative; thanks for making our lockdown a bit easier sir.

Awesome. I learned a lot. I would live to see some info on putting Lithium batteries in a solar setup.

Really good information Andrew. Thank you to you both

I’ve a lithium and matched with a redarc BCDC the advantages are amazing . Just the weight and capacity are enough on why I really like my set up. Steve 🇦🇺

Great video, Andrew. I have just got into lithium power, all the factors of this new technology add up and significantly outweigh the larger initial outlay in dollar terms. I won't even mention the weight savings

Great video and really helpful. The comment about Prismatic cells confused me as it conflicted with some other research I have done. What I have identified is that some manufacturers provide protection both in terms of physical (explosion proof jacket) and electrical (internal fuses) at a cell level. Prismatic cells are bigger and therefore both more dangerous in the case of explosion and cylinder cells. Cylindrical cells because there are more of them, have more redundancy at a cell level so a problem with a single is less likely to be as serious. So it may be more true to say that the quality of the cells used is more important, and a reflection of cost, than whether they are prismatic or cylinder.

Thanks Andrew, stay safe and healthy!

Really nice video Andrew. Heiner seems to really know his stuff.

thank you for other great detail video on new type battley system as look put together 24v down 12v system for over land tour build in my truck

FYI: Pb Crystal batterie are still available in OZ...

You asked all the right questions, and Heiner answered very well. The first thing he answered well, was that the Lithium battery case is just a "housing" of the bits inside, so that case and how it looks is the thing that actually confuses everything...because if the look the same, then it should be the same, and that is where the issue starts. Lithiums are fantastic BUT you have to match and design it to work how you want, and unless you are technical at heart, you will struggle. You just started to touch on connecting multiple batteries at the end of the clip, and that is really when it gets complicated...if you need 24V or >200AH...then you really need to match and understand....whereas AGM's you can really still connect them in parallel and/or serial as you see fit, and when you need to...LifePo4 need planning. Great Video.

Great info Andrew! Great idea to go to the shop and compare....

That was great never could get my head around all that in the past but know light bulb has gone on. Thank you 👍👍

So informative, thanks for doing this for us.

Super great information given here. Thank you Andrew.

I learned a lot from this. Thank you. I could put a lithium starter under my seat in my Defender but then I heard 1. The price and 2. The trickle charge issue. So I'll stick with AGM for my starter battery.

Very informative, Thank you.

Love your work Andrew! Keep it up! I had so many questions about Lithium batteries and this is very insightful and answer almost all my questions, except 1. Almost all battery chargers and gauges measure the voltage of the battery to determine its state of charge. But since the Lithium battery has a virtually constant voltage (until shutoff), how do you measure/determine its state of charge?

Brilliant, really enjoyed this video.

Great video. Can you charge a lithium battery with a Epever mppt charge controller. I believe it has a special setting??

Great subject, great video, thank you.

I learned all of this when I quit smoking and started vaping , hahaha. Li-on batteries are great. Seems like there could be a little capacitor that would at least allow the charger to "see" the battery when its flat though. It will get normal really soon. AGM batteries are gonna be antiques .....maybe in the morning

Looks so funny when you pick it up like that. Very good video

Exceptional explanation... thank you so very much!

Thank you both for the information. I am getting a much better understanding of lithium technology.

Great content as always

Great content... yet another ripper flick mate. Cheers

Interesting to see that AGMs (and FLAs) still "win" for certain applications such as under the hood of a car. Also, the guy wrongly said that a high current draw from an AGM battery lessens the capacity. That is not true. It doesn't significantly lessen the capacity of the battery, it just lessens the effective capacity of the battery at that higher amperage draw. For example, if a 100Ah rated AGM battery has 50Ah of usable energy (without damage to the battery) rated at the 20 hour drain rate, that means you can draw 2.5A for 20 hours to get 50Ah out of the battery (assuming a healthy fully charged battery). However if you instead put a 25A load on that same fully charged battery, then you wont get 2 hours @ 25A. You might only get 1.5 hours, but that doesn't mean the battery dropped to only 37.5 Ah usable energy. You can still extract the "missing" 12.5 Ah, just at a slower rate (such as the 2.5A rate). I suggest that draining the batteries either way (either 2.5A for 20 hours) or 25A for 1.5 hours, then 2.5A for 5 hours (both are 50Ah of drain), will leave the battery is a similar state of charge (around 50%). If you don't believe me, try it. I usually do capacity tests on batteries that way. I use a high drain rate until my inverter beeps (usually at 10.5V under load), then I lighten the load and keep going.

I just bought an Ultra lead carbon battery, which so far seems amazing in terms of charging speed from Solar and can go to deeper discharge than AGM. (same price as AGM) Biggest issue for me with battery systems is the ridiculous prices for the DC to DC chargers like red arc.

Mark Jennings You are correct in the price for the Battery management systems as lithium set up is expensive (chargers or bms), i have a back up power system in the house and was advised not to go lithium because of the risk of thermal runaway inside a house. AGM's have there down side but until lithium batteries is improved a bit more i will stick with the old tried and tested AGM batteries.

The best explanation ever, thankyou👍👍

The most important question and answer (for me!) was the very last one; "why 2x 100ah batteries v. 1x 200ah battery." To add to the electrical engineering answer Heiner gave, unlike AGM/Flooded batteries, you can easily add more batteries to the system later. That means you can start with 1x 100ah battery + DC/DC charger+charger/inverter+MPPT solar controller for your system and then after your cardiologist bills are paid due to the sticker shock, you can buy another 100ah lithium and add it into the system ;-)

Should i/should i not wire a winch to my secondary lithium battery and use winch while running engine, or always wire winch to lead acid starter battery and use when engine running?

Excellent discussion. However, here in the US we have a wide range of weather. During the year I can travel areas where the temperature can vary between -10 (-23C) to 115 (46C). At his time lithium batteries have complications when dealing with weather extremes that my 8D AGM’s don’t have. I’m excited about lithium battery potential, but right now they don’t answer all my needs like an AGM does.

so can it be a combo hybrid batery liuthiu + agm sort of ?

Great vid. I have a boat that has an electric motor on it and it is 55lb which is basically 55 amp draw for one hour at max speed or am I miss understanding it. My battery is agm century 120 ah and I noticed the other day when I was trolling my boat was not moving as good as it used to do. I charge my battery every day on trickle charge when it’s not in use and never charge it in hot days or cold nights and didn’t charge it for month as my charger was broken now I feel like my battery is not working right. What’s a good test I can do before I spend more money as I am looking at 200ah so when I go for two day bream comps and may not be able to charge it will this be better fit for my needs. Sry if I make no sense but I’m confused as at first the battery was great n charged it after use very much straight away till it sits on the float part of charging now when I go fishing if I troll for 35 mins straight at middle point of my motors power draw the boat doesn’t move as good as it used to. Great channel and picked up few tips.

Fantastic informative video Andrew (as usual). Thanks so much for putting it together and thanks to Heiner too. Really informative and contains great, simple to digest detail. Lithium all the way. 👍

I really like this video as with most of them. I would like to point out something in regards to the dc to dc charger vs. charging from the alternator. If you have a Smart alternator which many new or late model vehicles have you must use a dc to dc charger with any battery, Gel, Lead acid, Lithium etc... in order to achieve a full charge.

Excellent Andrew - Thanks

How long can the battery keep its charge if it isnt being used?

if you want to start your car with it, there are AGM batteries on the market eg.: Enersys EP, XE; Odyssey extreme, Powersafe SBS, Interstate MTZ,... example: Enersys XE16 12V 16Ah Crankingamps: >600A or Odyssey PC2250 12V 125Ah Crankingamps: 2250A

Great video. Was tempted to replace my AGM battery with Lithium but now I need to ensure my inverter and my charge controller can stop charging once the battery is full, meaning i will need to further invest in a shunt.

@traveleats6833

most smart charge controllers know when to shut off and that is why you use a proper charge controller rather than a dumb isolator switch.

you gonna love the lithium, enjoy. Surprised that your redarc jump started the management system. I have to jump start the management system on my batteries. I wonder if its because I have 2 75 amp batteries and you only had one for the test. Will be interesting to see once you have fitted both??? Maybe a follow up on this episode? or maybe its the relion management system vs the Amtron? As you saw on mine I have linked my started motor to the lithium batteries using a kill switch, so its hassle free to jump start both ways if needed.

Awesome information! 👍

I had a lead crystal battery have a cell or 2 drop late last year and it was replaced under warranty. I note this only to note that they clearly could supply the replacement in Australia.

Andrew. I am looking to replace my three 110amp 7 year old Full River AGM deep cycle batteries . The batteries are housed in a rack under the tray of my Iveco 4x4. I became keen on the Enerdrive e power B tec lithium batteries. Reading the fine print the Enerdrive are not suitable for fitment in exposed weather eg under the tray for a 4x4 truck or under the chasis of a caravan.Is that the norm for lithium in general? Also some suppliers are saying lithium should not be connected in series. Say if I want to add an additional battery later.

How are you monitoring the state of charge?

Great video! 👌 Very clearly presented information and makes this new world of lithium 12V batteries much less daunting for amateurs like me! 😊 Keep up the good work.

@@4xoverland it certainly was! One question that I have after watching the video is if I am to upgrade my camper trailer system from AGM to lithium, would it be better to have 2 x 100-120ah batteries connected in parallel or one large capacity 200ah battery? i.e. Does having 2 x batteries provide a redundancy if one fails, or if one fails are you in trouble? Cheers

Hi Andrew , if I wanted to wire up two 120amh lithium batteries to run a 24v electric motor do you wire them up the same as normal AGM batteries ? Also would a 24v Ctek charger be ok to charge them as a single unit ? I am under the impression that the Ctek chargers also shut off when the batteries are fully charged and I correct ? Sorry for the list of questions but I am not very good with electric tech . Thanks and keep up the good work.

Hi Andrew, I have a 120ah Lead crystal battery have done for a few years, after watching the video and the comment of possibly not being able to purchase Lead crystal batteries in Australia anymore, I had a look and there appears that you can still purchase them. Trailer camper Australia was one of the sellers.

Companies in the USA are selling these now with 11 year warranties. But I live in a hot climate, so how long are these going to last in the Oz heat?

I learned a few things with this one, recently I also chose lithium. However, my biggest concern while choosing was not mentioned in this video: cold weather charging. Most lithium batteries bms will shut down bellow 0º to avoid damaging the cells. That's the only thing I would have liked to see mentioned in here. (Not a concern in Australia or South Africa I assume). Thanks for the great videos.

Can you please do a video about the different between lithium and lead crystal battery please

Am i understanding this correctly, apart from weight difference, I am guessing its ideal as a 2nd battery for fridges, access etc and being charged by a BCDC charger... has a super fast recharge time.... and the fact it lasts longer before going flat because it has more usable Amp power in store... is that right and do they come in 120amp?

I am curious about how to set up and run duel batteries. It would be nice if you make a video about duel battery use also, that includes conventional and lithium.

Something to remember here is the information from Suppliers IS NOT ALWAYS CORRECT! I work in a battery shop & there is a very well known brand of lithium Motorcycle battery sold all over the world that advertise they are Prismatic cells. Every single one I have cracked open have lithium polymer cells with no protective casing! I dont sell these by the way.

So could I replace my truck battery under the hood with this battery and just have the alternator on my truck charge it?

Just on the whole charging thing, Victron, a very well respected manufacturer of such things, produce LiFePO4 batteries and will sell you a split charge system for it. The battery data sheets ask for almost identical charging specs to lead acid batteries.

So for engine compartment stored batteries. Extreme heat with lithiums is a concern in the desert temps of 100°f plus. Under hood temps can reach 200°f plus. The interior/cab alone here in south west Arizona can reach 122°f.

I’ve just installed a 1500w inverter to make coffees on the road, I’ve got 1x 100amp agm and 1x 75amp agm with my car running and a 40amp dcdc charger charging the 2 batteries the voltage drops to 11.6v from 14.4v . I’ll be interested to see how many cycles I get .

as a RC enthusiast, the LiFePO4 batteries are the future if you want reliability, long term storage and cold weather operation. If you want larger capacity, straight lithium cells like a 18650. If you need high draw, fast discharge and recharge, LIPO. and I define high draw as 30-40C, as in draining 100ah in 5 - 10 minutes. Think drones or arc welding.
