3S/4S 40A 60A Li-ion lítium akkumulátortöltő védőkártya 18650 BMS fúrómotorhoz 11,1V 12,6V/14,8V 16,8V Javítás/kiegyensúlyozás
3S/4S 40A 60A Li-ion Lithium Battery Charger Protection Board 18650 BMS For Drill Motor 11.1V 12.6V/14.8V 16.8V Enhance/Balance
Description
Product name: 3 strings of 12.6V 40A lithium battery protection board
Charging voltage: DC 12.6V~13.6V
Continuous discharge current: Maximum 40A (If the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 20A
Balanced version Product size: 41*61*4mm
Enhanced version Product size: 41*55*4mm
Applicable options: suitable for a 4.2V lithium battery with a nominal voltage of 3.7V and a full charge
(Including 18650, 26650, polymer lithium battery), can be punched below 170W

Note 1: Successful drilling requires 3 10C-20C power batteries, or 6 5C-10C power batteries (recommended power battery models: sony vtc4, vtc4A, vtc5A, vtc6) OV and 12.6V cable, using 3 square millimeters of copper Wire or more (nickel sheet cannot be used)
Note 2: Connect 0V, 4.2V, 8.4V, 12.6V strictly according to the figure. Do not touch any components on the board when soldering wires. Don't short-circuit intentionally.
Note 3: When the battery is welded or charged for the first time, as long as the single battery exceeds 4.2V, the "430" resistor will heat and discharge (discharge to about 4.19V and stop heating). If the "430" resistor is heating up severely, please check whether it is connected to the wrong wire.
Product name: 4 series 14.8V 16.8V 40A lithium battery protection board
Charging voltage: DC 16.8V~17V
Continuous discharge current: Maximum 40A (If the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 20A
Scale version Product size: 45*60*4mm
Enhanced version Product size: 44*55*4mm
Applicable options: suitable for a 4.2V lithium battery with a nominal voltage of 3.7V and a full charge
(Including 18650, 26650, polymer lithium battery), can be punched below 170W

Note 1: The electric drill needs 3 15C-20C power batteries, or 6 10C-15C power batteries (normal 18650 cannot start the electric drill!!!).

Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V strictly according to the diagram, do not intentionally short-circuit.


Note 3: When using a brushed motor load, try to connect non-polar capacitors (withstand voltage above 25V, capacity 10uF-100uF) between the positive and negative poles of the motor to prevent reverse peaks of the motor. Disconnect the MOS tube.

Note 4: 4 sets of batteries are used in series. Please ensure the voltage of each set of batteries. If they are not the same, please fill up each set of batteries separately and then use them in series. In the discharge test, the battery pack with a faster voltage drop is an inferior battery.
