Power Up Your Adventure With Our SUPER Range of Dual Battery Kits

For those prioritising a robust off-grid setup, consider the practical upgrade of a dual battery kit for your vehicle, caravan or camping configuration. Supercheap Auto offers reliable dual battery kits that enable you to efficiently power your devices and effortlessly monitor battery levels.

Contrary to the distinct battery setups of 4WD vehicles or daily drives, caravans can equally benefit from the advantages offered by a dual battery kit. The merits of a dual battery setup are extensive, providing a power level unattainable with a single battery. As the name suggests, a dual battery setup allows for the integration of a secondary battery into your caravan or motorhome, dedicated specifically to powering accessories and appliances.

For caravans or motorhomes, auxiliary batteries prove invaluable during camping excursions without access to a reliable power source. With a dual battery setup, run all your appliances, lights, and accessories without concerns about depleting the power needed to start your engine when it's time to pack up camp. Supercheap Auto offers a range of dual battery kits and isolators to facilitate easy setup and ensure correct power source utilisation.

To complete your setup, explore our comprehensive selection of trailer parts and accessories available at Supercheap Auto. Whether you prefer online shopping or wish to visit your local Supercheap Auto store for more information, we are here to assist you.

Frequently Asked Questions - Dual Battery Kits

Can I charge the auxiliary battery using solar panels?

Yes, numerous dual battery kits are designed to be compatible with solar panels. The integration is facilitated by connecting solar panels to the auxiliary battery through a dedicated solar charger or charge controller. This setup allows for efficient charging of the battery, whether during camping activities or when the vehicle is parked.

How does a caravan dual battery kit work?

A standard dual battery kit generally comprises a dual battery isolator, wiring, and fuses. The dual battery isolator serves as the crucial component that connects the main battery and auxiliary battery. This connection enables the simultaneous charging of both batteries when the engine is running. Importantly, the isolator prevents power from flowing back to the main battery when the engine is off, safeguarding it from depletion and ensuring you are not left stranded.
