Home->PCM for Li-ion/Li-Polymer Battery Packs ->For 6S~10S Packs (22.2V~37V)-> For 6S Packs (22.2V)

Battery Protection Circuit Module (BMS/PCM) for 6S 22.2V Li-ion/Li-Polymer Battery Packs

Part number: HCX-D675

Features and Benefits

   1.Protection Circuit Board for 22.2V 6S Li-ion and Li-Polymer battery pack;

2.PCM applies for 6 cells Li-ion/Li-Polymer 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 both Li-ion and Li-Polymer 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.
