Home->PCM for LiFePO4 Battery Packs ->For 11S~13S Packs (35.2-41.6V)-> For 13S Packs (41.6V)

Battery Management Systm (BMS) with SMBus 1.1, I2C, RS485, RS232 Communication protocol for 13S 41.6V LiFePO4 Battery Packs

Part number: HCX-D270

Features and Benefits

Programmable BMS with SMBus 1.1, I2C, RS485, RS232 Communication protocol1.Battery management circuit board with SMBus for 8S~16S
1.Protection Circuit Board for 13S 41.6V LiFePO4 battery pack;
2.PCB applies for 13 configuration LiFePO4 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 all the LiFePO4 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.
