Scope of application: lithium batteries with nominal voltages of 3.6V and 3.7V (including 18650, 26650, and 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 heat dissipation environment is not good, please reduce the load current)
Continuous charging current (upper limit): 10A
Standard version: suitable for electric drills with starting current below 40A and power below 65W.
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 (the ordinary 18650 cannot start the electric drill!!!); if the battery happens to be too small or the power of the electric drill is too high If it fails to start, please contact the store owner to tell you the solution.
Note 2: Wire 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, do not short circuit intentionally.
Note 3: When using a brush motor type load, 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 breaking 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 different, please charge each set of batteries separately before using them in series. . .
During the discharge test, the battery group whose voltage drops faster is a bad battery.
A note for some customers with poor electronic knowledge: Never mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 3 sets of batteries is, the better! (The use effect of 2 good batteries + 1 bad battery =The use effect of 3 poor batteries).
