4S 100A BMS 16.8V Lithium Battery BMS Li-ion/LMO Protection, Cell Balancing Module balance charging module
Description:
1. This protection plate is 4S in common use lithium battery protection plate (can be adjusted for How many strings
should be used), the default delivery is 4S ternary lithium.
2. specified chip, stable performance, support disconnect protection, over current protection, over discharge
protection, overload protection, with balance etc.
3 common use for “same port” and “different port”, the protection board uses 15 ultra low resistance high power
MOS tubes (8 discharge, 7 charge), in the same port mode can withstand the current of discharge 60A,
charge current 60A; Different modes of current discharge port 80A, charging current 60A.
4. Can be used for LMO. Ternary lithium battery. LCO battery packs (3.7V) etc.
