Why You Need a Dual Battery System for Off-Road Trips

When you’re heading bush or chasing remote tracks, reliability is a must. Whether it’s keeping the beers cold, charging your gear, or lighting up camp after dark, the last thing you want is to flatten your main battery. That’s where a dual battery setup comes into play, and if you’re serious about touring or camping off-grid, it’s a no-brainer.

What’s a Dual Battery System?

A dual battery system means you’ve got a second battery in your rig, totally separate from the one that starts your engine. This second battery runs all your accessories, like fridges, lights, and chargers, while your starter battery is left untouched, ready to kick the engine over when it’s time to hit the road again.

Why You’ll Want One for Your Next Off-Road Adventure

Don’t Get Caught Out with a Flat Battery

There’s nothing worse than waking up in the middle of nowhere with a dead battery. A dual battery system makes sure your starting battery stays charged no matter how much gear you’ve run overnight. No jump-starts, just peace of mind.

Power Up All Your Gear

Today’s 4WD setups are more kitted-out than ever. With a dual battery, you can run:

  • Your 12V fridge or freezer
  • LED camp lights and awning lights
  • UHF radio or air compressor
  • Inverters for laptops, drones or camera gear
  • USB and 12V sockets for phones, tablets, and other bits and pieces

And you can do all that without worrying about flattening your starter battery.

Go Further, Stay Longer

Planning to head off-grid? Whether you’re tackling the Gibb River Road, beach camping up north, or just posting up at a favourite river spot, a dual battery setup means you can stay longer without running out of juice. Add a solar panel into the mix, and you’re completely self-sufficient.

Ideal for Solar Charging

If you’ve got solar panels or plan to add them, a good DC-DC charger (like REDARC’s BCDC range) will keep your second battery topped up straight from the sun. That means no idling the engine and no need for a generator, just clean, quiet power at camp.

Easy to Build On

The beauty of a dual battery system is you can start simple and build it up. Add a battery box now, throw in solar later, or go full lithium with all the bells and whistles. Whatever your setup looks like, we’ll make sure it works the way you need it to.
