Battery Protection Circuit Module (BMS/PCM) for 14S 44.8V LiFePO4 Battery Packs
Features and Benefits
1. Protection Circuit Board for 44.8V 14S LiFePO4 battery pack;
2.PCM applies for 14 cells LiFePO4 battery pack with E-Switch integrated, E-Switch can totally turn off the output;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.With cell balance/equilibrium function;
5.Compatible with LiFePO4 cells;
6.How balancing function works? After battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down
