Home->PCM for LiFePO4 Battery Packs ->For 3S~4S Packs (9.6~12.8V)-> For 4S Packs (12.8V)

Protection Circuit Board(PCM) for 12.8V 4S LiFePO4 battery pack

Part number: HCX-D272

Features and Benefits

1.Protection Circuit Board for 12.8V 4S LiFePO4 battery pack;

2.PCB applies for 4 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.
