Quick update on this project. I decided to go with a power labs pl8 charger since it can do balance only charging. I charge with the banana leads until one cell is nearly full then switch to "accurate" charge with banana output disabled. I believe the cells are staying well balanced with my...

I should have mentioned that this is the end of the whole top-balance process. I've charged them all up in pairs then only connected them all in parallel to finish it off. I shut it down shortly after the post. They are all within 0.01v so I consider that a success. Now I will discharge them and...

The first discharge/charge cycle didn't go very well. When I started the balance charge, one cell jumped up in voltage way before the others causing the charge to slow to a crawl. I figured it was due to the resistance of the crappy bus bars that came with the packs. So I ordered two 36"x1"x1/8"...

Here we go! Cell fuve is off to an early lead

The stock L1 charger is like an L1.7 charger on 240V (which it does support with an adapter). Would save money on charger and a 3000w inverter should be enough to handle the 2880w this setup would pull.

Attempted to top balance but ended up charging each cell individually to 3 60v

The usable kwh of the gen1 is 10.9 so maybe target a 12kwh capacity? I'm kind of taking on a similar project. I have a 5.1kwh 24v pack that I intend to use for various purposes. Last night I dumped some of it into my gen2 volt (14.0kwh usable). I have a 3000w pure sine inverter 24v in, 120v...

I thought of a way to slightly rephrase/clarify my question. Probably comes down to the details of how a typical BMS works and my lack of knowledge of them. Say you're using solar power to charge a bank of 8 lifepo4 200ah packs in series. When the first cell hits 3.65v, the bms starts burning...

The configured voltages for LiFe look good. The 10.0v of the power supply was with regards to top charging all in parallel to 3.6v, on the top end it goes to 30v, 1200w. What would be the proper charging equipment for this use case if money were no object?

With a UP1350W (have to google it, I can't seem to find the manufacturer official website) which supports LiFe chemistry. I essentially intend it to be an "interactive" only battery. I'm not going to stick it in a trailer and forget about it while solar charges it and some load discharges it...
