3S 40A 12.6v Li-ion Lithium Battery Charger Protection Board

Description The 3S 40A 12.6V lithium-ion battery protection board safeguards your lithium batteries from overcharging, over-discharging, and short-circuiting. Suitable for starting current below 80A, power 135W below the drill. 3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery) 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. Specification: Charging voltage: 12.6V – 13.6V Continuous discharge current (upper limit): 40A Continuous charge current (upper limit): 20A Consuming current: Min 12uA; Max 24uA Overcharge protection voltage: 4.2V-4.3V Overcharge recovery voltage: 4.1V-4.2V Over-discharge protection voltage: 2.4V-2.6V Over voltage protection after over-discharge protection: Min 2.8V; Max 3.2V on 1C Discharge Over voltage protection after over-discharge protection: Min 3.2V; Max 3.8V on 2C Discharge Continuous Output Power: 504W – Resistive Load Screenshot Packing List: 1 x 3S 40A 12.6v Li-ion Lithium Battery Charger Protection Board
