18650 Battery Charger Module DIY Lithuim Battery 3s 12.6V 20A

3 strings of 12.6V 20A lithium battery protection board (with function – AUTO ) of application: lithium batteries with a nominal voltage of 3.6V and 3.7V (including 18650, 26650, and polymer lithium batteries) Continuous discharge current (upper limit): 20A (if the heat dissipation environment is not good, reduce the load current) Product weight: 4.3g Charging voltage: 12.6V – 13.0V Continuous charging current (upper limit): 10A Standard version: suitable for electric drills with starting current 40A and power 65W. Enhanced version: suitable for electric drills with starting current 60A and power 100W. Note 1: Three 15C-20C power batteries, or six 10C-15C power batteries are required to successfully the electric drill (ordinary 18650 cannot the electric drill ); if the battery happens to be too small or the power of the electric drill is too high Some of cannot be started, contact the to tell you the solution. Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the , do not intentionally short circuit. Note 3: When there is a load with a brush motor, a capacitor (10uF-1000uF) must be connected in parallel to the positive and negative terminals of the motor to prevent the reverse voltage generated by the motor from interfering with the protection board or breaking down the MOS tube. size: 59 x 20 x 3.4mm Material: PCB colour: green Package Contents: 5 x PCB Protection Board Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real . The measurement allowed is +/- 1-3cm.
