Buying guide

Dual battery and 12 V power explained

A second battery runs your fridge, lights and charging without touching the starting battery. Modern vehicles and lithium batteries change how that system should be built.

  1. Smart alternators

    Many late-model vehicles have smart alternators that vary their voltage. A simple isolator doesn't charge a second battery well from these, so a DC-DC charger is recommended (Redarc).

  2. Where lithium can go

    Lithium batteries must not go in the engine bay: the heat is too much (Redarc, Enerdrive). They go in the cabin, tub or canopy.

  3. Charge it correctly

    Lithium needs a charger with a lithium profile, and most can't be charged below 0 C unless the battery is heated. Don't mix battery brands or sizes in one system (Redarc).

  4. Sizing solar

    Work out how many watt-hours you use a day and divide by 5 to 6 sun hours to size your panels. A panel laid flat can lose up to 38% of its output (Enerdrive).

Choosing Switches and Wiring Accessories

Match the wiring method to your vehicle. Piggyback adaptors plug in between the factory connector and your driving light harness so your lights come on with high beam, with no cutting of factory wiring, which keeps the install clean and reversible. Plug and play harnesses handle the relay, fusing and switching in one loom, a far safer route than running unfused wire straight off the battery.

Buy the harness or adaptor made for your exact model and generation, because connector types change between updates of the same vehicle. It also pays to plan where switches will sit in the cabin before you start, so the finished job looks factory rather than tacked on. If wiring is not your thing, our Burwood workshop can handle the whole install.

Common questions

Do I need a DC-DC charger?

If your vehicle has a smart alternator, yes: isolators charge poorly from them. A DC-DC charger also gives the second battery the right charging profile, including for lithium (Redarc).

Can a lithium battery go under the bonnet?

No. Battery makers say lithium batteries can't handle engine bay heat and must not be installed there (Redarc, Enerdrive).

Lithium or AGM?

Lithium needs a charger with a lithium profile, a location out of the engine bay and, below 0 C, a heated battery to charge. Compare usable capacity and weight on each battery's specifications, and follow its maker's mounting guidance.

How much solar do I need for a fridge?

Add up your daily use in watt-hours, then divide by 5 to 6 sun hours (Redarc). Allow extra if the panel will lie flat or sit in shade.

Can I run my fridge off the starting battery?

You can, but you risk a flat battery and no start. A second battery with a DC-DC charger keeps the starting battery for the engine.
