Description:
4S 40A Balanced Version

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)
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.
Package Included:
1PC*4S 40A Li-ion Lithium Battery Protection Board

3S 40A Enhanced Version

Color: Green
Material: Electronic components
Role: 3 series 12.6V 40A lithium battery protection board
Scope of application: Lithium battery with nominal voltage of 3.6V and 3.7V (including 18650, 26650, polymer lithium battery)
Applies to: pre-transmission current 80A, power below 135W
Rated voltage: 12.6v
Charging voltage: 12.6V - 13.6V
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
Note:
Note 1: The successful start of electric drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can not start drill! ! !).
Note 2: Connect 0V, 4.2V, 8.4V, and 12.6V in strict accordance with the diagram. Do not intentionally short circuit.
Note 3: When using a brush motor type load, connect a non-polarity capacitor (voltage resistance 25V or more, capacity 10uF-100uF) in parallel with the positive and negative terminals of the motor to prevent the reverse voltage spike generated by the motor from interfering with the protection board or Break through the MOS tube.
Note 4: When connecting 3 batteries in series, please make sure that the voltage of each battery is the same. If not, please fill each battery separately and use it in series. . . In the discharge test, the battery with the faster voltage drop is the bad battery.
For some customers with poor electronic foundation, please explain: Balance charge is auxiliary function, try not to mix good battery and bad battery together! 3 sets of battery capacity/internal resistance is as close as possible! (2 good batteries + 1 Poor battery use effect = 3 bad battery use effects).
Product size: 5.5*4cm
Successfully starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can't start the drill! ! !).
Strictly follow the diagram to connect 0V, 4.2V, 8.4V, 12.6V, do not intentionally short circuit.
Note When using a brush motor type load, connect a non-polarity capacitor (voltage resistance 25V or more, capacity 10uF-100uF) in parallel with the positive and negative terminals of the motor to prevent the reverse voltage spike generated by the motor from interfering with the protection board or punching down the MOS. tube.
When connecting 3 sets of batteries in series, please make sure that the voltage of each set of batteries is the same. If not, please fill each set of batteries separately and use them in series. . . In the discharge test, the battery with the faster voltage drop is the bad battery.
For some customers with poor electronic foundation, please explain: Balance charge is auxiliary function, try not to mix good battery and bad battery together! 3 sets of battery capacity/internal resistance is as close as possible! (2 good batteries + 1 Poor battery use effect = 3 bad battery use effects).
