Battery Capacity Monitor
— Instruction (English version) —
This is a typical high precision current type battery capacity
monitor (also known as coulometer), designed to test the voltage，
current and capacity of a battery to help users know the state of a
battery in real time. This device has a memory function. It is
suitable for mobile and portable equipment using battery power
e.g. RV's, Marine, Mobility Vehicles, Remote Power, Instruments,
UPS etc..
This product is suitable for Lithium battery, Lithium Iron
Phosphate battery (LiFePO4), Lead-Acid battery and Nickel Metal
Hydride battery with a working voltage from 8V to 100V.
ø59 (diameter)*20 (depth)
Normal Operation:
Press key to voltage interface.
Press key to capacity interface.
press key again to current interface.
Press key to capacity percentage interface.
１． First, connect the current sampler/shunt in series with
negative pole of battery, the B- terminal on the shunt connects to
the Battery - (neg) terminal. P- on the shunt connects to power
output/charger - .
2．You require a standard insulated wire (0.3-0.75mm²). One end
of the standard wire connects to the Battery + (Pos) terminal and
the another end connects to any one of B+ on the current shunt.
3．Finally, connect the shunt to the Coulometer display using the
shielded wire/ cable (Supplied with Coulometer).

(2) Connection diagram of 100A/350A shunt
4． Connect and check the reading. Complete the connection as
shown and power on, the screen should display the battery
voltage current, capacity percentage and other information. If the
screen does not display, then please check the wire connections.
Next step, run a charge or discharge and check display current is
consistent with actual current. If the difference is large please
check the connections.
Attention: **IMPORTANT** Please connect as illustrated. The
shunt must be connected to the negative circuit，it must not be
connected to the positive circuit. If you wish to extend the
shielded wire, you must use the same cable/wire specification.
