Description

3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)
Scope: Nominal voltage of 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Product Size: 41 x 60 x 3.4mm (Balanced version)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 40A (if the cooling environment is not ideal, please reduce the load current )
Continuous charge current (upper limit): 20A

Balanced version: Suitable for electric drill with starting current below 80A and power below 170W .(with balanced charging function)

Note 1: For successful starting, the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (an ordinary 18650 battery can not start the drill!!).
Note 2: When you are wiring 0V, 4.2V, 8.4V, 12.6V, 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, it indicates the balance circuit is working. If the "430" resistance is heating without charging, check if the wrong wire is connected.
Note 4: Do not use a mix of different battery qualities, make sure each battery is the same in capacity and internal resistance. Balanced charge is only for auxiliary functions, try not to use a good quality battery with a poor quality battery simultaneously.

Package included:
