WARNING: This is a HIGH current device.
It is the installer’s responsibility to ensure all cabling meets the
requirements as stipulated on page 6 of this installation manual to ensure a
SAFE installation, particularly when upgrading with a higher capacity unit.
Failure to comply with the supplied installation instructions will void the warranty.

IMPORTANT SAFETY INFORMATION.
Please read this manual thoroughly before use and store in a safe place for
future reference.
WARNINGS.
• Explosive gases may escape from the battery during charging. Prevent flames and
sparks and provide adequate ventilation.
• Before charging, read the instructions.
• FOR CHARGING 12 VOLT AUTOMOTIVE BATTERIES ONLY.
• Do not attempt to charge non-rechargeable batteries.
• Never charge a frozen battery.
• Corrosive substances may escape from the battery during charging and damage
delicate surfaces. Store and charge in a suitable area.
• This appliance is not intended for use by young children or infirm persons unless they
have been adequately supervised by a responsible person to ensure that they can use
the appliance safely.
• Young children should be supervised to ensure that they do not play with the
appliance.
• Fit fuses as close to the batteries as possible to protect the cable in case of short
circuit.
FEATURES.
The DC-DC Charger is Intelli-Charge’s next generation in DC-DC charging. It has
been designed with next generation technology to ensure your DC-DC charging
experience is unrivalled. The DC-DC Charger features everything needed to maintain
the auxiliary battery to its optimum condition and to prolong battery life.
DUAL INPUT OPERATION
• The DC-DC Charger allows for simultaneous dual battery charging from both solar
and alternator inputs (9-32V) with no manual switching required. The unit prioritises
solar charging as its default and automatically adjusts to the alternator if sunlight is
insufficient, reducing the power usage placed on the vehicle’s electrical system.
TOUGH & RELIABLE
• DC-DC Charger is rated to IP68 & IP69K, ensuring it can withstand the toughest
of conditions. All connections into the DC-DC Charger are done via brass posts
and crimped terminals. Ideal for mounting in the engine bay. DC-DC Charger use
temperature compensation to ensure the battery receives the correct charge voltage
regardless of ambient temperatures. Raises the voltage in cooler climates while
reduces the voltage in warmer climates to ensure the battery does not boil.

SMART DC-DC CHARGING
• DC-DC Charger paired with Intelli-IQ supports advanced control of the dual battery
system including Bluetooth connectivity to an iOS or Android device. Note Intelli-IQ is
sold separately.
MULTI-CHEMISTRY CHARGING
• The DC-DC Charger range of charger’s suits today’s different battery technologies,
including everyday automotive batteries and the newer lithium battery technology.
For automotive batteries, multi-chemistry technology enables the user to tailor the
charging profile to suit the battery type: AGM, GEL, WET, Calcium and LiFePO4
batteries. For other types Lithium batteries, please check the battery’s datasheet and
see if DC-DC Charger is suitable for the charging profile before connecting.
PARALLEL CHARGING
• DC-DC Charger can be wired in parallel to provide more charging current for larger
systems. This flexibility gives users the option to add another DC-DC Charger into
their system should power requirements change. For example, two DC-DC Chargers
would provide a total charging current of 50A.
FUTURE PROOF
• DC-DC Charger was designed to stand the test of time. When DC-DC Charger is paired
with an Intelli-IQ, the firmware can be updated via Bluetooth ensuring DC-DC Charger
software is always up to date with the latest features.
SOLAR MPPT
• The DC-DC Charger utilises sophisticated MPPT (Maximum Power Point Tracking)
solar regular technology. MPPT maximises the power generated from the solar
panels to the auxiliary battery.
PROTECTIVE FEATURES.
SPARK-FREE PROTECTION
• The DC-DC Charger will not start charging the battery (no output) unless the load
is securely connected. It prevents the output leads from sparking due to accidental
short circuit making the charger safer to use around batteries.
REVERSE CONNECTION PROTECTION
• Reverse connections on input and output terminals does not damage DC-DC
Charger’s internal circuit. The DC-DC Charger detects reverse connection condition
and indicates whether input or output connection is reversed.
OVER AND UNDER VOLTAGE PROTECTION
• The charger will automatically shut down if there is an over voltage or under
voltage problem.
OVER TEMPERATURE PROTECTION
• The charger will lower its output current if the temperature of the unit begins to
overheat.
