Home->PCM for LiFePO4 Battery Packs ->For 6S~10S Packs (19.2-32V)-> For 7S Packs (22.4V)

Battery Protection Circuit Module (BMS/PCM) for 7S 22.4V LiFePO4 Battery Packs

Part number: HCX-DD410

Features and Benefits

   1.Protection Circuit Board for 22.4V 7S LiFePO4 battery pack;

2.PCM applies for 7 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.

7.PCM comes with all the voltage detection wires and connectors.
