Home->PCM for LiFePO4 Battery Packs ->For 14S~16S Packs (44.8V~51.2V)-> For 16S Packs (51.2V)

Battery management Systerm (PCM) for 51.2V 16S LiFePO4 battery pack

Part number: HCX-D131

Features and Benefits

1.Battery management circuit board for 51.2V 16S LiFePO4 battery pack;
2.BMS/PCB/PCM applies for 16cells 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.
