4S 40A Li-Ion Lithium Battery 18650 Charger BMS Protection Board Balanced Module

# BMS Protection Board Balanced Module Properties

Contion: New
Item: 4S 16.8V 40A lithium battery protection board
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, polymer lithium battery)
Charging voltage: 16.8V - 18.1V
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)
Continuous charge current (upper limit): 20A
Application: For Drill Motor
Type: Voltage Regulator
Balance Current: 100mA
Standard version: for starting current below 80A, power 135W below the drill. (Not balanced function)
Balanced version: suitable for starting current below 80A, power 220W below the drill. (with balance)


# BMS Protection Board Balanced Module Note:
1. The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill !!!).
2. strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
3. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
4. 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.


# BMS Protection Board Balanced Module Package Included:
1PC 4S 40A Li-ion Lithium Battery Protection Board
