BMS 2S 20A Protection Board

2S 20A Lithium Battery BMS Protection Board Standard Version

Battery Li-ion 18650 8.4V

Suitable for 2 pieces of 18650 batteries. It does not charge batteries. It is for battery protection.

     With this module you can quickly charge high capacity 2S lithium batteries, thanks to the voltage protections on it, it protects your batteries from being charged at high voltages and it also prevents the batteries from being damaged by preventing current from being drawn from your nearly depleted batteries.

     Batteries must be charged at limited currents. Charging batteries 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 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 battery life while saving time/power.
