BMS 4S 40A Protection Board Standard

4S 40A Lithium Battery BMS Protection Board Standard Version

Battery Li-ion 18650 16.8V

It is suitable for 4 batteries in series 18650. It does not charge the battery. It is for battery protection. It undertakes the balancing task.

     With this module you can quickly charge high capacity 4S 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 draw from your batteries that are about to run out.

     Batteries must definitely be charged at limited currents. Charging the 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 the batteries, they do not perform current control. It is appropriate to use them only for the purpose of protecting the batteries. You need to charge your batteries with a current controlled source together with your bms boards. 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 the battery life while saving time/power.
