3 series 11.1V 12V 12.6V 18650 lithium battery charging protective board can start electric drill 20A current

3 series 11.1v 12V 12.6V

(Combined with recovery function-aUTO Recovery)

Scope of application: Lithium batteries with nominal voltage with 3.6V and 3.7V (including 18650, 26650, lithium battery polymer)

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 use of load current)

Continuous charging current (upper limit): 10A

Standard Edition: Applicable to electric diamonds with a power below 40A and less than 65W.

Enhanced version: Applicable to electric diamonds with a power below 60A and less than 100W.

Note 1: Successful startup requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 cannot start electric drills!!!).

Note 2: Strictly follow the figure 0V, 4.2V, 8.4V, 12.6V, don't deliberately short circuit.

Note 3: When a load with a brush motor class, a non-polar capacitor must be connected in parallel on the positive and negative wiring end of the motor (above 25V, 10UF-100UF) to prevent the reverse peak voltage interference of the motor or the protective board orSpeed ​​through 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 not the same, please fill in each group of batteries alone and then use it in series.EssenceEssenceDuring the discharge test, the battery that drops rapidly is a difference battery.

For some customers with poor electronic foundations: Do not use good batteries and different batteries together! The capacity/internal resistance of the 3 sets of batteries, the better, the better!= The use of 3 different batteries).
