Home->PCM for LiFePO4 Battery Packs -> For 5S Packs (16V)

Battery Management System (BMS) for 5 cells in series 16V LiFePO4 Battery Packs

Part number: HCX-D546

Features and Benefits

1.Protection Circuit Board for 16V 5S LiFePO4 battery pack;

2.PCB applies for 5 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 until other cells reach the same voltage level. Therefore, it helps cells have longer service life.
