Electrical Accessories

About this range

Electrical accessories are the small parts that make a 12V touring setup work, from switches and power outlets to plugs, looms and control boxes. This collection covers the connectors and hardware you need to wire accessories into your 4WD cleanly and safely.

We carry gear from Narva, Piranha, Mean Mother and Low Voltage, including 50 amp Anderson-style plugs, rocker switches, driving light looms and 12V power panels. Buy online with Australia-wide shipping, or have your accessories wired in at our Burwood workshop.

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 4x4 electrical accessories

Start by mapping what you want to power and where. A fridge in the back needs a properly rated outlet on its own circuit, driving lights need a loom with a relay, and anything you connect and disconnect regularly, like a camper trailer feed, is a job for Anderson-style connectors that handle high current without heat build-up.

Quality matters more in a 4WD than a daily driver, because corrugations shake connections loose and dust finds every gap. Sealed switches, covered plugs and correctly sized cable protect the rest of your setup, and every circuit should be fused. If you are combining several accessories, a power control box or panel keeps the wiring organised and easier to fault-find later.

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.
