5S 18.5V Protection Circuit Module/PCM for Li-ion/Li-Polymer Battery Packs

Home->PCM for Li-ion/Li-Polymer Battery Packs -> For 5S Packs (18.5V)

PCM/BMS/PCB for 5 cells in series 18.5V Li-ion/Li-Polymer Battery Packs

Part number: HCX-D254

Features and Benefits

1.Battery Management System for 18.5V 5S Li-ion and Li-polymer battery pack;
2.BMS applies for 5 cells Li-ion/Li-polymer battery pack;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.The maximal working current :8A
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.
