Switch Electronic Module Connector Electronic Parts Product description Specifications: 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 Size:41 mm×55 mm×3.4mm/1.61 ×2.16×0.13in Detailed electrical parameters are shown in the picture Scope of application: Suitable for lithium batteries with a nominal voltage of 3.7V and a full voltage of 4.2V (including 18650, 26650, and polymer lithium batteries, there is no limitation on size) 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!!Recommended power battery models: SONY VTC4, VTC4A, VTC5A, and VTC6).). 2.Strictly according to the diagram wiring，0V/4.2V/8.4V/12.6V,Do not touch any components on the board when soldering the wire. 3.When welding the battery for the first time or charging, as long as a single battery exceeds 4.2V, the '430' resistor will heat up and discharge (discharge to about 4.19V and stop heating). If the '430' resistor is seriously hot (it is too hot to touch), please check whether the wrong wire is connected. 4.Do not mix the good battery and poor battery to use.The internal resistance of 3 battery capacity are closer will be better. Package includes： 2x40A 3S PCB Lithium Battery Charger Protection Board 1x1M/39.37in Nickel Strip 8mm
