These are 48v LiFePO4 battery packs. They contain 3x 5s 16v 52Ah sub-modules. They end up 15s2p configuration tested 95%-100%.  Modules yields 2500Wh.

These modules can be used as 48v on a variety of equipment and can be setup for DIY PowerWall applications. These modules come out of an energy storage application where the BMS has failed but the cells have on the average less than 100 cycles. The negative terminal is an XT90 with both pins in parallel and the positive is 3/8" ring terminal.

LiFePO4 is the safest Lithium chemistry as its less reactive. Lithium Iron Phosphate is the preferred chemistry on energy storage applications due its long cycle life usually in the 4000-6000 cycles.  The downside used to be their high price, but finally I can offer quality modules at around $100/kWh.  Limited quantities on these units.

BMS Recommended for these Modules:
For single or multiple modules used in parallel we recommend this 15s BMS
