Module wholesale, professional distribution of electronic components. Our products are wholesale prices, priority is given to large quantities. Products are of higher quality than the market and can be purchased with confidence.

Descriptions:

1. 3 strings 11.1V 12V 12.6V (Built-in recovery function-AUTO Recovery)
2. Scope of application: lithium batteries with nominal voltages of 3.6V and 3.7V (including 18650, 26650, lithium polymer batteries)
3. Product size: 59 * 20 * 3.4mm
4. Product weight: 4.3g
5. Charging voltage: 12.6V-13.0V
6. Continuous discharge current (upper limit): 20A (If the heat dissipation environment is not good, please reduce the load current to use)
7. Continuous charging current (upper limit): 10A
8. Standard version: suitable for electric drills with starting current below 40A and power below 65W.
9. Enhanced version: Suitable for electric drills with starting current below 60A and power below 100W.

Note 1: Successfully starting the electric drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 can not start the power drill !!!).

Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the figure, do not intentionally short circuit.

Note 3: When a load with brush motor is used, a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) must be connected in parallel with the positive and negative terminals of the motor to prevent the reverse spike voltage generated by the motor from interfering with the protection board or Break down the MOS tube.

Note 4: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are not the same, please charge each set of batteries separately and use them in series. . . During the discharge test, the group of batteries whose voltage drops rapidly is a poor battery.

For some customers with poor electronic foundation, please explain: Do not mix good batteries and poor batteries together! The closer the capacity / internal resistance of the 3 sets of batteries, the better! (2 good batteries + 1 poor battery) = The use of 3 poor batteries).

Package Included:

• 1pc * DC-12V 3S BMS With Protection Module 20A
