3S 40A Balance Li-ion 18650 BMS PCM Battery

Suitable for starting current below 80A, power 135W below the drill. (with balance) 3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)

Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)

Product Size: 41 * 60 * 3.4mm

Product weight: 9.8g

Charging voltage: 12.6V – 13.6V

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

Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 cannot start the drill!!).

Note 2: Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.

Note 3: When soldering the battery for the first time or while charging, as long as the single battery exceeds 4.2V, the “430” resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the “430” resistor is severely hot, check if the wrong line is connected.

For some of the poor basis of electronic customers to explain:

Balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect).
