Loved the video. It would be nice to repeat the desulphation phase (around 13 minutes in) with an oscilloscope instead of a multimeter but your theory sounds good to me (not that I'm particularly qualified).

Brilliant..My lead acid batts on the horse trailer were shot. So I took em out (2 12vdc paralleled (over 5yrs old)) and wondered if I could just plug in a 100Ahr Lifepo batt from one of my solar setups in their place. Should be ok.

If you want to jump start the charger with another 12 V battery, just insert a 10 watt 1 ohm resistor in line with the charge wire. That will limit the current to around 10 A max and it will rapidly drop off to around 1 amp as soon as the BMS turns on.

Thank you for sharing. If you have a Dc 2 DC charger for lithium battery on your vehicle and your charger has a solar input. Use that to charge your lithium battery with a normal lead acid charger. Your battery will see a voltage coming in and take that to fully charge and it is safe. Don’t be scared to charge a lithium battery with an ordinary battery charger. All that sales talk of you must use lithium charger to charge lithium battery is a way to convince you to spend more money for no reason. Your DC2DC lithium charger charger will do its job in charging a battery safely

Fascinating.

Just saved people and me a few bob.

great video, i wonder, since i just bought a 100ah lithium battery, if some of the same reasoning might apply to all the inverters out there that imply they should only be used with lead acid ?

I just use a more old-fashioned lead charger without desulfation.. or how it was spelled. 20amp. Use it when the sun fails for 2-3 days and the battery is getting low. It charges to 14,7 so i removed after 6-10 hours of charging just to be sure i dont get too close to 13,5+volts and certainly not anywhere 14,7 :)

that battery has a BMS in it. So why would it over charge anything if the BMS stops the charge when full?

@wwOsqueDew

True I was thinking the same thing.

a lifepo4 cell battery is 4s config and therefore wont reach max charge from a PB charger, that's all. The only other issue I might think is when in the desulf stage, I wonder if that might mess with the BMS in the lifepo4 battery. I doubt that tho. What you should do, is a capacity test, charge to full with a charger designed for lithium, then test the total AH you get from it right till the BMS cuts off, now do the same with a PB charger and see the difference. my bet is you will get about 80% of the capacity if you use a PB charger.

Good observation on the lead acid charger shut down with low Voltages. Not all BMSs are the same; this also applies to battery chargers. The most important feature in a BMS or charger is the temperature sensor shut down. If any of your devices does not have that, they are a fire hazard. Typically the BMS algorithm will balance the individual cells of the battery and control the amount of current for both charge and discharge while monitoring the temperature, besides shutting down the battery in case of a short circuit. As long as the charger's Voltage is higher than the battery's, the BMS will allow for charging.

I was hoping to use this charger to maintain a charge on the lithium. So if a lithium battery is not completely dead, and has 12+ volts, do you think 1) a conventional lead acid charger will work to maintain a 13.8+ voltage? 2) Do all lead acid chargers have this desulphation feature and can this feature cause a lithium battery to fail?

So, applying the second charger/battery effectively allows the BMS to reconnect, allowing a charge current. You woke the BMS up, and thus the CTek can see there is a battery there to charge.

MPPT solar charge controllers typically works with from 100v down to the voltage of your battery bank (12 - 24 or 48v) and automatically regulates down the higher voltage it gets from the solar panels to the voltage of you batteries (the voltage it gets from the solar panels need to be higher then the battery voltage and the higher it is the better). The voltage and ampere from solar panes varies during the day so the MPPT solar charge controller take the varying input and regulates it down to what is best for your batteries charging.

Generally speaking, switch mode 240V chargers need to see a battery voltage before they start to charge, so no, not in my experience.

Lithiums with an internal BMS will prohibit charging at or below 0C/32F, aid in balancing the cells and prevent charging over 14.7 VDC. If your lithium has no BMS, you MUST have a charger that allows setting the temp. coeff. to zero if you travel in areas less than 75-77F / 25C (to prevent charger from increasing charge voltage above 14.6 VDC in environments less than 25C). Even with an internal BMS (which often fail) it is good practice to set charger temp. coeff. to zero as a backup system. Any BMS can be reset by briefly connecting an identical charged battery in parallel, or any battery over about 6 volts as you showed... but briefly. Most Lithium 12V batts should be charged in BULK at 14.2-14.6 VDC (absolute max 14.6) and 0.2C (the number of amps equal to 20% of the batts amphour (Ah) capacity, then absorption at a constant 14.2-14.6 VDC and a falling current from 0.2C to 0.01C or less (from 20% C to 1% C or less). The classic "float" phase is not required (set float time to zero) but some batteries recommend a "topping" phase for lithiums. If you cannot set float time to zero, set max float voltage to 13.6 VDC... never higher, at 1 or 2 amps for minimum time or turn off charger. Most can also be fast charged by setting bulk and absorption currents to 0.5C (50% C) and of course voltage to 14.2-14.6 (max) depending on battery maker's specs. Never overcharge (so avoid "dumb" PWM solar controllers and smart chargers that go to 14.9), never charge if battery environment is at or less freezing point of water, never float or top at over 13.6, and never discharge below 10.5-10.8 VDC (depending on maker's specs). Over-discharge often occurs when using an inverter to provide AC power for appliances especially those with a big amp draw like a microwave... it is so easy to over-discharge. To avoid this, set the inverter low voltage discharge to 10.5-10.8 VDC depending on battery maker's specs (when in doubt use 10.8 as the low voltage cut-off). These things will provide you with many years of happy lithium use... although I personally use silicon dioxide (SiO2, "lead crystal") 6 volt x2 batteries to avoid ALL of these issues, including charging at -40C, discharging to dead zero, storage at dead zero / partial charge / full charge, fast charging at 0.3-0.35C, never floating, and allowing deep discharges far below 10.5 VDC when heavy appliances draw 0.5-1.0C (like an 1800 watt convection microwave). To save generator fuel when charging with inadequate solar, I cycle my two 6V SiO2 batts between 20-80% capavity (80-20% depth of discharge) and fully charge to 100% once a month. I live 24/7, 365 with just t two 6 volts. Trust me, I'm a doctor and a scientist.

The inbuilt charger of the car doesn't do all the fancy things a specialised external charger does. Especially true for old cars when electronics to do all these fancy features was expensive. So as long as the car isn't doing anything fancy, the BMS within the Lithium battery will take care. There literally are Lithium batteries that are marketed as replacement. The inbuilt electronics take care of the compatibility, user doesn't have to worry about anything. I should add that just like lead batteries are just bare batteries, you can also get bare 18650 cells. Now that definitely needs a specialised charger cuz it doesn't have a BMS inbuilt.

I replaced a 36 volt Lead acid battery with a 36 volt LiFeP04. The Tech told me that the range for LiFeP04 is 41.3 volts to 47 volts. The lead acid charger output is below 41.3 volts so, it will not charge to LiFeP04 at all. I will either have to modify the charger to output 47 Volts or get a charger with a 47 volt output.

A lead acid charger, especially non "smart" models will easily charge a 12V LIPO but some nuances have to be considered. The first nuance is that you don't want to float charge a LIPO indefinitely. Remove it from the charger once the maximum charge is reached. LIPOs don't last as long if 100% max charge voltage is met and maintained for too long, especially when not in use. Also, if you pull the LIPO down too low, many lead acid chargers won't enter bulk charge mode when they see a voltage below some cutoff number, say

I wouldn’t use lithium iron phosphate batteries as starter batteries, that chemistry is not meant for surge starting. Thats what lead acid is for. And it absolutely doesn’t need surges or pulses or floats. That’s why you buy a lithium charger, not that that charger is going to hurt it. It’s just not optimal for its life.

So your argument about LFP batteries being unsuitable for does not exactly stack up. I had just a balancing BMS on it so had to be careful not to drain it. Also LFP batteries are sensitive to low temperatures, which was not an issue in our mild climate. The issue with LFP as start batteries is the BMS must be able to protect the battery but also allow high surge start currents. This makes it more costly than for deep cycle use. Actually Lead Acid batteries are a very good option for starting so there is no particular advantage to using LFP for that. There was no particular difference between the charge curves from the LA CTek and the LFP Ctek. Agreed that LFP batteries definitely do not like a permanent float charge with no load.
