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 * 55 * 3.4mm (Enhanced Version), 41 * 60 * 3.4mm (Balanced version)
Product weight: 8.8g (enhanced version), 9.8g (balanced version)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current )
Continuous charge current (upper limit): 20A
Enhanced version:Suitable for electric drill with starting current below 80A and power below 130W .(without balanced function)
Balanced version: Suitable for electric drill with starting current below 80A and power below 170W .(with balanced charging function)
Note 1: To successful starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!!).
Note 3: When the battery is charging,the "430" resistance heating is normal,it means the balance circuit is working.If the "430" resistance is also heating without charging,please check if the wrong wire is connected.
