This 4S 100A BMS is mainly designed for 3.2V Lifepo4 cells.This protection board consists of 3 strings, 4 strings lithium battery protection board (the universal version adjusts the corresponding components according to actual needs), adopts mature protection circuit, special IC and supports disconnection protection, and imports high current ultra low internal resistance MOS (The internal resistance of a single MOS) is as low as 3 millionths. It has perfect and stable charging and discharging protection functions. The battery core is balanced, the balance current is appropriate, and the balanced heat is reasonable, which does not affect the performance of the battery pack.

 

Common use for "same port" and "different port", the protection board uses 15 high-power of ultra-low resistance MOS tube (discharge of 8, charging of 7), in the same port mode can support the discharge current 60A, charging current 60A and different port mode discharge current 80A, charging current 60A.
