Description
4S 40A Li-ion Lithium Battery 18650 Charger PCB BMS Protection Board with Balance For Drill Motor 14.8V 16.8V Lipo Cell Module
Now this 4S 40A balance version has upgrade to new !
1, increased anti-interference function,
2, reduce the large current heat by 30%,
3, starting power increased from 135W to 220W (4S40A)
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)
Charging voltage: 16.8V – 18.1V
Continuous charge current (upper limit): 20A
Board Size: 46*60*3.4mm
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Note:this item is Balanced version .If you need other Version,please contact us.The 2 version price is different
Balanced version: suitable for starting current below 80A, power 135W below the drill.(with balance)
Note 1: The successful start of the electric drill requires four 15C-20C power batteries, or eight 10C-15C power batteries (ordinary 18650 can not start drill! ! !).
Note 2: Connect 0V, 4.2V, 8.4V, 12.6V, and 16.8V in strict accordance with the diagram. Do not intentionally short circuit.
Note 3: When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected.
Note 4: 4 groups of batteries in series, please ensure 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.
