Owners Manual
Overview
These slimline lithium iron phosphate (LiFePO4) batteries
are for situations where space is at a premium. They mea-
sure just 75mm high and weigh less than 25kgs. Each is
fitted with 120A Anderson input and output plugs for easy
connection to your equipment or solar charger output. Each
utilises the same battery management system found in the
standard LiFePO4 battery series for safe operation at all
times, plus a handy voltage & capacity readout.
Warnings
This battery utlises LiFePO4 chemistry which is the safest
type of lithium chemistry for use in mobile vehicle applica-
tions. However you should adhere to the following warn-
ings:
• Avoid mechanical shock of the battery.
• Do not expose the battery to fire or open flame.
• Do not pierce the battery.
• Do not disassemble the battery or its housing.
• Do not drill into or modify the enclosure in any way.
• Do not expose to moisture or water ingress
• Do not store the battery below -20°C or above 60°C
Installation
This battery has been designed for permanent installation
in a car, caravan or 4WD as a portable power source for
connected appliances. The battery must be installed and af-
fixed to a surface using the mounting tabs on the housing to
prevent it from becoming a projectile in a vehicle accident.
The slimline design allows the battery to be mounted behind
or under a seat, into custom cabinets or on the internal walls
of your camper or caravan.
Ensure your installation location will provide adequate ven-
tilation (25mm clear space around the battery), taking into
consideration the operating discharge temperature of the
battery. This battery is not suitable for installation in:
• Vehicle engine bay or a high heat environment.
• External/exposed locations where moisture is present.
• Inside compartments dedicated to carrying gas.
If in doubt we encourage you to engage a professional to
install the battery into your vehicles power system.
Once installed in a suitable location
the battery can be connected
using the dual 120A input/output
terminals on the side of the battery
enclosure. You should use the
included connection cables for this
purpose as the mating connector is
not suitable for use with a genuine
grey Anderson SB120 connector (it
does mate with a blue SB120 connector, should you wish to
terminate your own cabling). The included cable is 16mm2
(4AWG) gauge and suitable for carrying the full discharge
rating of the battery. Ensure any connected wiring matches
this specification. It must be suitable for carrying up to 100A
current.
Note that there is no internal fuse protection on the
Anderson style output connections. For safety you MUST use
an external in-line fuse rated to 100A for each connection.
The BMS is designed for up to 100A continuous charge
and discharge. Please take this into consideration when
connecting your chosen method of charging and your
appliance loads.
Charging
LiFePO4 lithium batteries require slightly different charging
parameters compared to their lead acid counterparts. As
such you should use a AC charger, DC-DC charger or solar
regulator which features a LiFePO4 compatible mode. The
IMPORTANT NOTE: Battery is supplied at 30% charge from the factory for safety compliance.
The battery must be fully charged before rst use.

recommended charging voltage for these batteries
is 14.2-14.6V. The recommended charge current is
50A.
IMPORTANT NOTE: Do not use a Voltage Sensitive
Relay (VSR) with this battery. A VSR connected to
an auxiliary lithium and main lead acid battery
will not operate correctly due to the higher
cell voltage in the lithium battery. A LiFePO4
compatible DC to DC charger is a superior
alternative.
Battery Management System
This battery is fitted with an internal battery
management system or BMS. This internal circuit
ensures safer discharging and charging. The BMS is
designed to prevent overvoltage via overcharging,
cell damage from overdischarging and dangerous
conditions such as short circuits and excessive
temperature.
LCD Readout
The front mounted LCD readout provides battery
capacity and voltage reading. To conserve energy
the display will switch off after a period of time.
Press the button underneath the display to activate
the display.
System Configurations
This battery can be wired up to a maximum of 4
units in series (12-48V), and in parallel there is no
limit to the number that may be used in a single
system.
