4S 40A 18650 Li-Ion Lithium Battery Charger PCB Board Protec

Detailed Information About The Product:

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
Enhanced version: for starting current below 80A, power 135W below the good.(Not balanced function)
Note:this item is Enhanced version
Note 1: The successful start of the good requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the good!!).
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- capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse goodke from the motor. Break the MOS tube.
Note 4: 4 groups of batteries in series, please that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge , the voltage drop faster battery that group is poor battery.
