Product Description

Features:
 Programmable BMS with SMBus , I2C, Communication protocol

1.Protection Circuit Board for 5S 18.5V  Li-ion and Li-Polymer battery pack;

2.PCB applies for 5 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 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.

BEST SERIES BMS mainly designed based on TI chips, TIBQ78350+BQ76940/BQ76930/BQ76940, and the mosfets for discharge and charge current we mainly use IRF4310/IRF3207/IRF1404 (Only for reference), the specified parameters as below (all the logical parameters are adjustable from software).

(Note: the pictures or parameters in this data sheet are only for your reference, those possibly could be different from the ones you will order. Due to the upgrading of the Hardware/Firmware/Software,Characteristics subject to change without notice, for more information, please contact our technical engineers by email: [email protected]
