Home->PCM for LiFePO4 Battery Packs ->For 11S~13S Packs (35.2-41.6V)-> For 12S Packs (38.4V)

Battery Protection Circuit Module (BMS/PCM) for 12S 38.4V LiFePO4 Battery Packs

Part number: HCX-D836

Features and Benefits

1. Protection Circuit Board for 38.4V 12S LiFePO4 battery pack;

2.PCM applies for 12 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
