Dual Battery System

Dual Battery Systems and Kits for 4WDs, Caravans and Camping

A dual battery system gives you extra power to run your gear while you travel or camp. It works with your main battery but keeps things separate so you can run appliances without draining the one that starts your engine.

These systems are popular in 4WDs caravans and camper trailers across Australia. From weekend trips to remote touring, you can find a setup to suit your rig and power demands.

What is a dual battery system and why do I need one?

It is a setup that lets you add a second battery to power your gear without using the main battery that starts your engine.
This means you can run a fridge, lights or a water pump while parked without draining your start battery. It suits anyone camping touring or free camping who wants to stay powered without mains supply or leaving the engine running.

Do I need a special battery for a dual battery setup?

Dual battery systems use deep cycle batteries because they are built to deliver power over a long period.
AGM and lithium are the most common options. Lithium batteries are lighter and last longer but cost more. AGM batteries are a solid choice for most setups and work well for running fridges lights and other 12V gear.

How to Choose the Right Kit for Your Setup

The right dual battery kit depends on how much power you use and what kind of trips you take. If you are just running lights or charging devices a small setup will do the job. If you want to run a fridge for a few days or power bigger gear you will need a larger battery with more amp hours.

Also think about how you want to build your setup. Some kits are better for utes or canopies while others suit caravans or RVs. Look for something that fits your space and lets you expand later if needed. If you plan to stay longer or add solar make sure the kit can handle extra input and more gear down the track.
