Scope: Nominal voltage of 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Charging voltage: 16.8V – 18.1V
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)
Continuous charge current (upper limit): 20A
Balanced version: suitable for electric drill with starting current below 80A and power below 230W .(with balanced charging function)
Note 1: To successfully start, the drill requires three 15C-20C power batteries, or eight 10C-15C power batteries (ordinary 18650 batteries can not start the drill!!).
Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, and 16.8V, please do it strictly according to the wiring diagram. Do not deliberately make it short-circuit.
Note 3: When the battery is charging, the “430” resistance heating is normal, which means the balance circuit works. If the “430” resistance is also heating without charging, please check if the wrong wire is connected.
Note 4: 4 groups of batteries in series, please ensure that the voltage of each group of batteries is not the same, please fill each battery separately and then use in series. In the Discharge test, the voltage drops faster battery the group is poor battery.
