Note 1: Successful start of the electric drill requires 3 power batteries of 15C-20C, or 6 power batteries of 10C-15C (ordinary 18650 cannot start the electric drill!! !); if it happens to be the battery is too small or the power of the electric drill is too large Please contact the owner to tell you how to solve the problem.
Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, do not intentionally short-circuit.
Note 3: For loads with brushed motors, a capacitor (10uF-1000uF) must be connected in parallel to 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 puncturing the MOS tube.
Note 4: When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please charge each group of batteries separately and then use them in series.
Never mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 3 sets of batteries, the better! (2 good batteries + 1 poor battery use effect = 3 poor battery usage effects).
