Features and Benefits

1.Battery Management System for 19.2V 6S LiFePO4 battery pack;
2.BMS applies for 6 cells LiFePO4 battery pack;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.With cell balance/equilibrium function;
5.Compatible with all the 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 until other cells reach the same voltage level. Therefore, it helps cells have longer service life.
