Why a Quality Wiring Kit Matters for Your Dual Battery Setup

If you're setting up a dual battery system in your 4WD, caravan, camper or canopy, the wiring you use is just as important as the batteries themselves. Undersized or poor-quality cable can lead to voltage drop, reduced charging efficiency, and underperformance of your entire 12V setup.

KickAss Dual Battery Wiring Kits are Built Tough

The first thing you'll notice when you pick up a KickAss wiring kit is the weight. That’s the result of properly thick, high-quality copper cable designed to carry serious current with minimal voltage drop, even across longer distances.

We don’t skimp on copper, and it shows. Whether you're running power to your rear canopy, a second battery under the tray, or a DCDC charger in your van, you’ll get reliable voltage delivery every time.

Everything You Need in One Kit

Each KickAss kit is packed with top-shelf components that make your install easier, safer, and more durable:

  • Heavy-duty twin core 8B&S cable – thick, flexible and ready for off-road conditions
  • 3-pin Anderson-style connector – ideal for powering multiple accessories
  • Pre-installed midi fuse holders – protects your setup from surges and short circuits
  • Crimp lugs, heat shrink, corrugated conduit – all included so you’re ready to go

Everything’s designed to work together – and work hard – with no cheap knock-offs or guesswork involved.

FAQ

What size wiring kit do I need for my setup?

The right size depends on the distance between your batteries and the current draw of your setup. Longer runs and higher loads require thicker cable. Our kits are available in multiple lengths to suit everything from ute trays to full-size caravans. If you’re unsure, give our team a call or drop into a store – we’re happy to help.

Can I use this kit with a DCDC charger?

Yes – KickAss wiring kits are fully compatible with DCDC chargers. The heavy-duty 8B&S twin core cable is designed to handle the current draw and minimise voltage drop, making it ideal for powering DCDC setups reliably.

What makes KickAss wiring kits different from cheaper options?

Our kits are built with high-quality copper cable and include premium components like pre-installed midi fuse holders, genuine-style connectors, and protective conduit. You’ll get reliable performance, safer installs, and longer-lasting gear – with no shortcuts or cheap substitutes.
