Maximum output current:20A
Quiescent current: less than 30uA
Charging voltage: 12.6V-13.0V
Continuous discharge current(upper limit):20A (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current(upper limit):10A
Enhanced version: suitable for electric drills with starting current 60A and power 100W.
Note 1: 3 15C-20C power batteries, or 6 10C-15C power batteries are needed to start the electric drill successfully (ordinary 18650 cannot start the electric drill!!); if the battery is too small or the power of the electric drill is too If some cause cannot be started, please contact the owner to tell you the solution.
Note 2: Strictly connect 0V, 4.2V, 8.4V, 12.6V according to the diagram, and 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 with the positive and negative terminals of the motor to prevent the reverse voltage generated by the motor from interfering with the protection board o
