4S 40A Charger Module for Drill Motor 14.8V 16.8V Lipo Cell Module Description

2 set Electronic Accessories:1 x 4S 40A Li-ion Lithium Battery Protection Board & 20 x Battery Holder Brackets
18650 cylindrical battery holder, fire retardant ABS+PC materials.Crack edge with the slot, with the firm, It can accomodate size; Battery installation hole diameter 18mm, 2-linked structure.Nickel plate vibration test can be conducted without attachment to any device.
Suitable for all types of battery assembly including do it option.Please note, installation requires top and bottom piece to work.
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 drill.(Not balanced function)
Model: 18650
Size: 4 x 2cm / 1.6 x 0.8 inch (LxW)
Inner Dia: 1.8cm / 0.7 inch
Note:this item is Enhanced version
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- 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 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 test, the voltage drop faster battery that group is poor battery.
