74V lithium battery BMS, 3.7V cell 20S li-ion battery BMS, 72-74V 40A BMS, For 74V 20Ah, 74V 30Ah, 74V 40Ah, 74V 50Ah, 74V 80Ah, 100Ah lithium ion battery pack. With balance function.
Features
1. It is suitable for 20S 74V lithium ion battery pack.
2. With functions of protection from voltage, current detection, balance function, including over-current, overvoltage, under-voltage and short circuit protection.
3. This BMS has applied with high quality IC chip specially for lithium battery protection purpose .highly detection
precision degree on over-charge,over-discharge,voltage balancing ,and with detection on wires disconnection functions,
with three layers of over-discharge and over-current detections and delay times in detecting process.( Over-current 1,
over current 2,short circuit protection ),with charging protection functions at the charging port so as to avoid reverse
connection problem from the charger . short-circuit of charging port ,with two layers protection against over-voltage
when charging :This is The BMS for 20 series 74V(84v) lithium ion battery pack with 40Aconstant discharge current
and 15A charging current
The charge and discharge port is different.
