Features：
Programmable BMS with SMBus , I2C/HDQ Communication protocol
1.Protection Circuit Board for 12S 44.4V Li-ion and Li-Polymer battery pack;
2.PCB applies for 12 configuration Li-ion and 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 all the Li-ion and LiPolymer 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.
7.This BMS is designed for 3S ~ 96S Battery packs, can be used on Li-ion, Li-Polymer, LiFePO4, with max. Continuous discharge and charge current @ 200A, and it is integrated with SMBUS, I2C, HDQ optional communications protocol for battery pack monitoring, fuel/gas gauge management, communicating with your applications, can accurately read your battery pack’s SOC and SOH information. The communicatiuon function is removeable, can remove it if there is no need.
8.BEST series is designed as high current BMS, can carry 200A continuously, the built-in electric fan will cool down the heating from BMS automatically during working. It is designed as charging and discharging at the same / different terminal, contact us for different terminal (cost effective) if needed.
9.BEST series BMS mainly designed based on SEIKO and TI chips , the SMBus/Fuel Gauge is based on TI BQ34Z100, the specified parameters as reference as below.
