150PCS 3S 40A Balance/Enhanced 18650 Li-ion Battery BMS Protection Board
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 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
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.
