This Lithium ion battery protection PCB protect single Lithium ion batteries. 4A continous current
Lithium ion protection is necessary, as Lithium ion will explode when they are shorted circuit or overcharged, and damaged when they are over discharged.
After Lithium ion is connected to the PCB, the board protect individual batteries from:
1. Over charging - Disconnect circuit when either battery is over 4.25V
2. Over discharging - Disconnect circuit when either battery is lower than 2.5V
3. Short curcuit protection - Disconnect when short circuit is detected
