9. : Low voltage alarm. When voltage is lower than LVP
value, the capacity will auto clear.
LVP
10. : turn on/off backlight alarm. After turning on LBR, when
the remain capacity is lower than 20% or voltage islower than
LVP, the backlight will flashing to alarm. When charging current
is higher than STI, the backlight will also flash.
LBR
11. : Communication Address.
ADS
12. : the value of current clear. After no-load current clear,
the shunt might make current higher than zero, which can set
PAI. When current is lower than the set value, the current value
will zero.
PAI
13. : the voltage value of max capacity. When battery
voltage is higher than OVP, the capacity will auto fill up.

Wiring Diagram
1.Connect the battery positive pole to the BAT+ of shunt,
connect the battery negative pole to the “-” of shunt.
2.The shunt must be series connected between battery and load.
3.Use the shielded cable connect the display board with measure
module.
4.Measure module should be fixed in a ventilated place.
Note
Set Capacity
1.Known the battery capacity value, can directly set.
2.Unknown the battery capacity value:
2.1Set the BAT to 0 and clear the capacity.
2.2Fully charge battery.
2.3Discharge the battery to empty, set the display capacity
value to BAT, and set BPC to 0%.
