MODEL: FBM08A10C / FBM08A35C
LIPPERT ITEM NO.: 2021124459/ 2021124534
USER MANUAL
* Product picture for reference only
Furrion battery monitor measures voltage, current, and battery
capacity in real time. It can help user accurately understand the
status of battery pack, and includes a power-down memory
function.
This product works with 8V~30V battery pack, such as the most
common RV deep cycle; Wet cell, AGM and Lithium batteries.
● Model FBM08A10C should be used for battery current that is
less than 100A.
● Model FBM08A35C should be used for battery current that is
larger than 100A and less than 350A.

Mounting the Shunt
Secure the shunt by using #4 or 3mm
screws with pan heads (not included),
to prevent accidental contact. There are
3 holes provided for mounting on the
shunt as shown.
NOTE: Mounting at least 2 holes is recommended. Do not place in
or cover with insulating material to allow adequate ventilation for
cooling.
Mounting the Power Monitor
Cut a 2⅛" (54.5mm) round hole on the equipment panel, tighten the
installation supporter with butterfly

nut to clamp to the panel as shown.
NOTE: The “equipment panel” is
not included.
Connection
1. Connect the shunt in series with the negative circuit of the
battery pack as illustrated. Ensure the ends of the shunt
marked B- and P- are connected correctly as illustrated.
2. Connect a fused (5A max) AWG#18 to AWG#22 wire between
the shunt and a 12V+ supply as illustrated. Using a 2-2.5mm
slotted screwdriver is recommended to connect the shunt.
3. Connect the provided shielded wire between the shunt and
battery monitor as illustrated.
NOTE: The length of the shielded wire is 32.8 feet (10m).
Ensure the shunt and monitor are within reach. The shielded
wire can not be spliced to add length.
WHAT’S IN THE BOX
● Battery Monitor
● Shunt Resistor
● Shielded Cable Wire
● Mounting Clamp Bracket
● User Manual
● Warranty Manual
INSTALLATION
CAUTION
● Do not put the battery monitor in direct sunlight, or in the
environment below 14°F (-10°C) or above 140°F (60°C) for a
prolonged period, which will shorten the lifetime of the LCD
screen.
● The shunt is recommended to be put as close as possible
to the battery, but not be exposed directly to the elements,
e.g. rain.
● The shunt must be mechanically secured, as its metal
exposed parts are GND and if not secured could cause
unwanted shorts, fire, or even an explosion of the battery.
● Ensure wires connected to the battery are properly mounted
– nuts must be tightened securely, so that the wires don’t
move, get loose during vibrations.
NOTE: Most power consuming equipment utilizes the RV chassis
frame as a current return path to the battery. Therefore the battery
negative is bonded typically very close in proximity to the chassis.
The shunt must be added in-line between the battery and chassis
frame for accurate use of the meter. No other power consuming
component can be attached to B-, all loads must connect to P-.
