Description:
This Lithium ion battery for protection PCB protect single Lithium ion batteries with 8A continuous current.
Lithium ion for 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 for 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.
For Protection I C: for Seiko S-8254AAK Datasheet.
For Protection MOSFET: 4x AO4407A.
