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 41x60x3.4mm/1.6x2.4x0.13"

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 an balanced version BMS PCB(with equalized charging).

3. The successful start of the drill requires three 10C-20C power battery, or six 5C-10C 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.
