Battery Protection Circuit Module (BMS/PCM) for 5S 16V LiFePO4 Battery Packs

Part number: HCX-D826

Features and Benefits

1. Protection Circuit Board for16V 5S LiFePO4 battery pack;

2.PCM 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
