Custom Power Solutions
Our dual battery systems are ideal for 4WDs, caravans, campers, and work vehicles that need reliable auxiliary power. We install everything from under-bonnet batteries to full in-cabin setups, with all wiring neatly integrated and fuse-protected.
REDARC BCDC chargers are commonly used for efficient charging on the move, and we also install battery monitors, isolators, and load control panels. Every install is designed to match how you travel and what you need to power—whether it's a fridge, lighting system, air compressor, or tool kit.
We also troubleshoot existing systems and replace underperforming setups with more efficient solutions tailored to current demands.

- Caravan & camper setups
- Monitors & power sockets
Our systems help you travel longer, run more gear, and rest easy knowing your starting battery stays protected.
Why install a dual battery system in your vehicle?
A dual battery system gives you a second battery to run accessories like fridges, lights, and power inverters without draining your main starter battery. This is especially important for off-grid camping, 4WD touring, and trade vehicles where consistent power is critical.
What’s the best battery type for a dual battery system?
It depends on your needs, but AGM, lithium, and deep-cycle lead-acid batteries are common. Lithium offers the best performance and weight savings, while AGM is more affordable. Battery type must be matched with the right charger for optimal performance.
Can a dual battery system run a fridge overnight?
Yes, if installed and sized correctly. A 100Ah deep-cycle battery can typically power a standard 12V fridge for 1–2 days, depending on usage and ambient temperature. Pairing with a solar panel can extend this dramatically for longer trips.
