Home->PCM for Li-ion/Li-Polymer Battery Packs ->For 11S~13S Packs (40.7V~48.1V)-> For 13S Packs (48.1V)

Battery Protection Circuit Board (PCB) for 13 cells in series 48.1V Li-ion/Li-Polymer Battery Packs

Part number: HCX-D528

Features and Benefits

 1.Protection Circuit Board for 48.1V 13S Li-ion and Li-Polymer battery pack;

2.PCB applies for 13 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.
