3-string 11.1V 12V 12.6V 18650 Lithium Battery Protection Board Can Start Electric Drill 20A CurrentItem NO.: 3S20A

3S 11.1V 12V 12.6V 18650 Lithium Battery Protection Board 20A

Product Information:

3 series of 12.6V 20A lithium battery protection boards (with built-in recovery function - AUTO Recovery)

Scope of application: Lithium batteries with nominal voltages of 3.6V and 3.7V (including 18650, 26650, polymer lithium batteries)

Product size: 59 * 20 * 3.4mm

Product weight: 4.3g

Charging voltage: 12.6V -13.0V

Continuous discharge current (upper limit): 20A (If the cooling environment is not good, please reduce the load current for use)

Continuous charging current (upper limit): 10A

Standard version: suitable for electric drills with a starting current of less than 40A and a power of less than 65W.

Enhanced version: suitable for electric drills with a starting current of less than 60A and a power of less than 100W.

Attention 1: Successfully starting the drill requires 3 15C-20C power batteries or 6 10C-15C power batteries (regular 18650 cannot start the drill!!!).

Attention 2: Strictly follow the wiring diagram for 0V, 4.2V, 8.4V, and 12.6V, and do not intentionally short circuit.

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

Note 4: When connecting three sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If not, please fully charge each set of batteries separately before using them in series... During the discharge test, the group of batteries with a faster voltage drop is a poor battery.
