Home->PCM for LiFePO4 Battery Packs ->For 17S~19S Packs (54.4V~60.8V)-> For 19S Packs (60.8V)

Battery Protection Circuit Module (BMS/PCM) for 19S 60.8V LiFePO4 Battery Packs

Part number: HCX-D682V1

Features and Benefits

 1. Protection Circuit Board for 60.8V 19S LiFePO4 battery pack;

2.PCM applies for 19 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
