3 cells 8A Li-ion Lithium 18650 14450 Battery Input Ouput Protection PCB 12.6V
 

Description:

This Lithium ion battery protection PCB protect single Lithium ion batteries with 8A continuous 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 4.35V.

2. Over discharging - Disconnect circuit when either battery is lower than 2.7V.

3. Short curcuit protection - Disconnect when short circuit is detected.

Connection:

B+ - TO +ve of the 1st battery.

B1 - TO -ve of the 1st battery and +ve of the 2nd battery.

B2 - TO -ve of the 2nd battery and +ve of the 3rd battery.

B3 - NO connection.

B- - TO -ve of the 3rd battery.

P+ - TO +ve of load/input.

P- - TO -ve of load/input.
