Description
ADVENTURE KINGS 25AMP DC-DC CHARGER
MK2 LITHIUM COMPATIBLE (WITH MPPT SOLAR)
SOLAR PRIORITY DUAL-INPUT CHARGING
Can accept solar and alternator input (combined up to 25A output) at the same time for fast and efficicent charging and will prioritise solar over alternator to save fuel and reduce load on your engine.
THE BRAINS OF YOUR DUAL BATTERY SYSTEM
Isolates your batteries when your vehicle is off and properly charges from your alternator/starter battery while you’re driving. Designed for vehicles with or without smart alternators thanks to ignition sensing. The Kings DC-DC Charger is a multi-stage charger and battery isolator all in one! The updated Mk2 version builds on the success of the Adventure Kings Mk1 DC-DC charger and is ready to take your 12V dual battery system to the next level.
LITHIUM (LIFEPO4) CHARGE CAPABILITY
Specially programmed charge pattern specific to Lithium LiFePO4 batteries. Plus Kings DC-DC chargers can be set to charge most 12V lead acid batteries including wet/flooded, AGM Deep Cycle and Calcium Maintenance Free.
DESIGNED, TESTED AND ENGINEERED IN AUSTRALIA
We teamed up with a Brisbane-based Engineering and R+D company – Intelliquip Solutions so that every step of development was achieved in-house in Australia. That included writing over 10,000 lines of code, designing the unique circuit boards and housings, prototyping, component selection and all the laboratory and real world testing.
EXTREME TEMPERATURE, FULL OUTPUT (ETFO) CHARGING TECHNOLOGY
Adventure Kings DC-DC Chargers can output their stated 20Amps of charge even in constant, extremely hot ambient temperatures of up to 60°C* and internal temperatures around 90°C*. Reporting back to the charging chip there are two temperature sensors that monitor different parts of the circuit board and electronics to protect and regulate the unit for high efficiency and longevity – plus there’s an external battery-mounted temp sensor for highly accurate charge compensation.
INDUSTRIAL GRADE COMPONENTS
Industrial grade components from the USA and Japan are a step above commercial grade and are rated to suit higher working temperatures – plus we’ve innovated a new way to mount high-current wires to circuit boards for the ideal electrical connection and so it’s rugged enough to take on Australian off-road conditions.
BUILT TOUGH FOR AUSSIE CONDITIONS
A tough alloy housing means it is able to survive harsh conditions while being engineered with a built in heat sink for excellent passive cooling. It’s properly protected against reverse polarity, short circuiting, under/over voltage, over current as well as over temperature and battery under/over temperature.
