Feature
1.100 brand new and high quality
2.Suitable for i-ion Lithium Battery
3 strings of 11.1V 12V 12.6V 18650 lithium battery charging protection board can start electric drill 20A current
BMS 3 strings 12.6V 20A lithium battery protection board (with recovery function - AUTO Recovery)
This product is an enhanced version: it is suitable for electric drills with starting current below 60A. 3 strings of 12.6V 20A lithium battery protection board (with recovery function - AUTO Recovery).
Scope of application: lithium batteries with a nominal voltage of 3.6V and 3.7V (including 18650, 26650, and polymer lithium batteries).
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 to use).
Continuous charging current (upper limit): 10A.
This product is an enhanced version: it is suitable for electric drills with starting current below 60A.
Note 1: Three 15C-20C power batteries, or six 10C-15C power batteries are required to successfully start the electric drill (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 Some of them cannot be started, please contact the store owner to tell you the solution.
Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, 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 peak voltage generated by the motor from interfering with the protection board or breaking down the MOS tube.
Note 4: When 3 sets of batteries are connected in series, please ensure that the voltage of each set of batteries is the same, if not, please fully charge each set of batteries separately and then use them in series. . .
During the discharge test, the group of batteries whose voltage drops faster is a poor battery.
Explain to some customers with poor electronic foundation: Do not use good batteries and bad batteries together! The closer the capacity/internal resistance of the three batteries is, the better! (The effect of using 2 good batteries , 1 bad battery = 3 poor battery usage effects).
