3S 40A BMS Balance

3S 40A Bms Balance Lithium Battery Protection Board

3 Series Cell Battery Li-ion 18650 12.6V Drill Electric Screwdriver

3 pieces of 15-20C batteries must be used in drills. Or 2x3 pieces of 10c-15C batteries must be used. Standard 18650 batteries cannot be used in drill-like applications.

The battery connection is shown in pictures 2 and 3. More than one group of 3 batteries can be connected in parallel. An incorrect connection will damage the product and the batteries.

     With this module you can quickly charge high capacity 3S lithium batteries, thanks to the voltage protections on it, it protects your batteries from being charged at high voltages and also prevents damage to the batteries by preventing current from being drawn from your batteries that are about to run out.

     Batteries must be charged at limited currents. Charging a battery without current control causes the life of the batteries to decrease. Similarly, drawing high current rapidly from the batteries also damages the batteries. Although Bms products appear to charge batteries, they do not perform current control. It is appropriate to use them only for battery protection purposes. You need to charge your batteries with your bms boards using a current controlled source. The battery charging current should be at levels such as 1/10  2/10 of the battery capacity. Remember, charging or discharging at very high current will reduce battery life while saving time/power.
