Installation
1. Make sure the battery you wired is 12.8V 4S LiFePo4.
2. Connect the RED WIRE with your battery positive pole,
Connect the BLACK WIRE with your battery negative pole.
3. Series a current sensor resistor between the battery negative pole and the load/charger (also we called output negative).
The recommended value of this current sensor is 0.005~0.05 ohm, depended on your load's working current.
If you have a BMS in your battery-pack, you can use the series current sensor resistor on this BMS, then you do not
need to do above job.
.
4. Connect the GREEN WIRE with the load/charger output negative terminal, after above "current sensor resistor".
End of installation.
Caution:
1. The Black and Green wire should be connected properly, if not the charging and discharging status and fuel gauge will
be reversed and in correct.
2. Please read this manual and understand attached schematic drawing before connect any wire!
