11 products, one complete system

A dual battery setup is usually a battery, a DC-DC charger, a solar controller and a monitor, bought separately and wired in one at a time. Topo builds them into one steel unit. You connect it to the vehicle once, then plug in what it's built for.

It stays fitted, it comes out when you need it

Once it's connected, a Topo unit stays in the vehicle and keeps the fridge running day and night, charging as you drive and leaving the starter battery alone. When you want it somewhere else, it unplugs and lifts out by the handle. Change vehicles and it comes with you, because the DC-DC charger lives inside the unit. The next vehicle only needs a charge connection fitted.

Gear that gets used deserves looking after

Book your unit in for a function test and a service before or after a big trip, or any time it doesn't feel right. We service the whole system, battery included. If something needs fixing, we repair it rather than replace it, so the unit stays on the road and out of landfill.

In WA, bring it to our Perth workshop. From anywhere else in Australia, send it in.

Australian made and supported

Every unit is designed and built in our Western Australian workshop. When you call or email, you reach the people who built it.

Built by a team with 60+ years of combined experience in 12V, marine, agricultural and off-grid power.

From people who use them

Six Google reviews, word for word.

I bought a Centrefire battery system for my 4x4 to power my fridge. It's super convenient because it's so portable and I can use it in my boat and also carry about the campsite. Charges super fast and ran my fridge for a week on a single charge. Killer product can recommend.

I have the Topo 144 A/H battery system, it works flawlessly, has multiple charging inputs and super reliable! And best of all, the after sales service and advice from the business owner is exceptional! Highly recommend!!!

Matt HancockGoogle review

I have had centerfire 72 for three years and have loved its versatility and reliability. I made a mistake and exposed it to high voltage which caused an issue. I received outstanding service from Ronnie and he helped me firstly diagnose the issue, juggle 12v needs on my car so we could continue our holiday in the North West and finally promptly repaired the issue with minimal charge. Great product, even better service!

You probably need less power than you think

Keep the fridge cold and the lights on, and never touch your starter battery.
