8S 29.6V Battery Management Systm (BMS) with SMBus 1.1, I2C, RS485, RS232 Communication protocol Li-ion/Li-Polymer Battery Packs
Features and Benefits
Programmable BMS with SMBus 1.1, I2C, RS485, RS232 Communication protocol1.Battery management circuit board with SMBus for 8S~16S
1.Battery management system for 29.6V 8S Li-ion and Li-polymer battery pack;
2.BMS applies for 8 cells 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.
