72V 60Amp Battery management System

$95.86

74V lithium battery BMS, 3.7V cell 20S li-ion battery BMS, 72-74V 40A/50A/60A BMS

Feature

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  40A/50A/60A constant  discharge current  

and 15A charging current  .the charge and discharge port is different.
