Home->PCM for Li-ion/Li-Polymer Battery Packs ->For 6S~10S Packs (22.2V~37V)-> For 8S Packs (29.6V)

Battery Protection Circuit Board (PCB) for 8S Cells 29.6V Battery Packs

Part number: HCX-D256

Features and Benefits

1.Battery management system for 29.6V 8S Li-ion and Li-polymer battery pack;
2.BMS applies for 8cells Li-ion/Li-polymer battery pack;
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.
