3 string 40A lithium lipo battery protective board module.

Enhanced version with/without balanced function, applicable to electric drills/drill motor with starting current below 80A, power below 130W, resistive Load below 504W.

Ideal 3S 40A 3S40A li-ion lithium battery 18650 charger protection board BMS PCB 11.1V 12.6V cell charging protecting module.

Specifications

Charging Voltage: 12.6V~13.6V

Continuous Discharge Current (upper limit): 40A(If the cooling environment is not good, please reduce the use of load current.)

Continuous Charge Current (upper limit): 20A

Size: About 41x55x3.4mm/1.6x2.2x0.13"

Scope: Nominal voltage of 3.6V, 3.7V lithium battery(including 18650, 26650, lithium polymer battery)

Attentions

1. Please allow tiny size deviations due to human measurement.

2. This item is an enhanced version BMS PCB without any equalized charging.

3. 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!!).

4. Strictly according to wiring guide 0V, 4.2V, 8.4V, 12.6V, do not touch any components on the board while soldering the wire to avoid short circuit.

5. Do not mix good batteries with bad ones.

6. The closer the internal resistance of the three battery capacities is the better.

7. When charging the battery, the "430" resistor heat is normal, indicating that the equalization circuit is working; if the "430" resistor is also hot in the uncharged state, please check if the wrong line is connected.

Package Included

1 x 3S 40A Protection Board

Integrated 10 imported low internal resistance MOS tubes, continuous discharge 40A, 100mA equalizing current, suitable for electric drills, sprayers, LED lights, low power inverters, etc.

Ideal 4S 40A li-ion battery 18650 charger BMS PCB protection board with balance for drill motor 14.8V 16.8V lipo cell module.

Specifications

Charging Voltage: 16.8V~18.1V

Continuous Discharge Current (upper limit): 40A(If the cooling environment is not good, please reduce the use of load current.)

Continuous Charge Current (upper limit): 20A

Size: About 46x60x3.4mm/1.8x2.4x0.13"

Scope: Nominal voltage of 3.6V, 3.7V lithium battery(including 18650, 26650, lithium polymer battery)

Attentions

1. Please allow tiny size deviations due to human measurement.

2. This item is a balanced version BMS PCB.

3. The successful start of the drill requires four 10C-20C power battery, or eight 5C-10C power battery(ordinary 18650 can not start the drill!!).

4. Strictly according to wiring guide 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not touch any components on the board while soldering the wire to avoid short circuit.

5. When soldering the battery for the first time or when charging, as long as a single battery exceeds 4.2V, the "430" resistor will heat up and discharge (stopping heating when discharged to 4.19V or so). If the "430" resistor is severely heated (it's too hot to touch), please check if the wrong line is connected.

6. When connecting 4 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are different, please charge each group of batteries individually and reconnect it in series. In the discharge test, the battery with a faster voltage drop is a poor battery.
