It is very important to use a BMS to manage these LiFePO4 Battery Cells.  Here’s Why
LiFePO4 chemistry is easily damaged by over charging/discharging, over/under temperature, and especially low temperature charging.  Use a BMS that monitors each series-connected cell (or group of parallel connected cells) and has a low-temperature cutoff.

2 reviews for CALB 3.2V 230Ah LiFePO4 Battery Cells – Grade A++

  1. EF Basham

    I bought 64 of these cells for a new class super-C motorhome based on a 2022 Freightliner Cascadia chassis. I’ve replaced the 4 ea x group 31 factory batteries for engine starting (2000A) with this new combination house + traction battery with 4000Ah @ 13.8 VDC to store 55.2 KW-h. All of the cells tested 245 Ah or more, when discharged to 3.0 Vpc in this system. A REC BMS supervises the temperature, state of charge, and 12KW diesel APU, which feeds into 3 ea Victron Multiplus II 2×120 inverters to supply 360 A of charge current. The battery bank can be charged by shore power, solar, APU, or engine alternator for redundancy. Under this usage, the CALB batteries should last 20+ years, given these are aviation grade cells and not commodity grade EV cells or worse – used cells that are flooding the market. A defining feature of the CALB cell is that it requires NO COMPRESSION, while other brands need 600+ lbs of compressive force to prevent premature failure.
