Product Detail

Description:

100% Brand New and High Quality

Please note before purchase: This product only contains one circuit board, used for 3 packs 18650 battery, not 3pcs items, please pay attention and understanding. thank you!

This Lithium ion battery protection PCB protect single Lithium ion batteries. 8A continous current w/ Balancing current 42mA per cell , fit for 10.8v 11.1v 12.6V 18650 lithium battery protection board

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
B3 - 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
B- - TO -ve of the 3rd battery
P+ - TO +ve of load/input
P- - TO -ve of load/input

Protection IC: Seiko S-8254AAQVA Datasheet
Protection MOSFET: 4x AO4407A
