ITEM NAME:4S 40A Li-ion Lithium 18650 Battery PCB Protection Board Standard version LJ Integrated 10 low load resistance MOS tube, continuous discharge 40A, 100mA balanced current, for electric drill/sprayer/ LED lights/low power inverter. 4S 16.8V 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) Charging voltage: 16.8V - 18.1V 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 Board Size:45*55*3.4mm Standard version: suitable for starting current below 60A, power 100W below the drill.(Not balanced function) Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube..Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!). Break the MOS tube.
