We only have the standard version
3 series 12.6V 20A lithium battery protection boards (with Recovery function -AUTO Recovery)
Scope of application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, polymer lithium battery)
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 drill with starting current below 40A and power below 65W.
Enhanced version: Suitable for electric drill with starting current below 60A and power below 100W.
Note 1: Successfully start the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can not start the drill! ! !) .
Note 2: Wire 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, do not intentionally short circuit.
Note 3: When the load of the brush motor is loaded, a non-polar capacitor (voltage 25V or more, capacity 10uF-100uF) 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 breakdown of 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 not, please fill each group of batteries separately and then use them in series. In the discharge test, the group of batteries whose voltage drops faster is the differential battery.
For some customers with poor electronic foundation, please explain: do not mix good batteries with poor batteries! The closer the capacity/internal resistance of the 3 batteries, the better! (The use effect of 2 good batteries +1 poor battery = the use effect of 3 poor batteries).
