Scope of application: suitable for 3.6V 3.7V nominal voltage lithium battery (including 18650, 26650 lithium polymer batteries).
PRODUCT：
SIZE: 59*20*3.4MM ;PRODUCT WEIGHT: 4.4G ;Charging voltage: 12.6V-13V;Max output current: 20A ;Max output power/charging power: 252W.
Note 1: 3 x 15C-20C power batteries are required to successfully start the drill, or 6 x 10C-15C power batteries (ordinary 18650 cannot start the drill!!).
Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When there is a load such as a brush motor, a non-polar capacitor must be connected in parallel at the positive and negative terminals of the motor (Withstand voltage above 25V, capacity 10UF-100UF), to prevent the reverse spike voltage generated by the motor from interfering with the protection board or breaking down 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 it is different, please fill each group of batteries separately and then use them in series. . During the discharge test, the group of cells with a faster voltage drop is a poor battery.
