About Topo DC Power

Australian made. Built for those who know the difference.

Topo DC Power is a family-owned Australian manufacturer specialising in compact, portable and powerful 12V lithium battery and dual battery systems.

Built on over 60 years of combined industry experience across marine, automotive, agricultural and off-grid power, Topo was founded on a simple belief: better engineering should make life simpler, not more complicated.

We design and manufacture our products in Western Australia, bringing together intelligent power management, rugged construction and practical functionality into compact, plug-and-play systems.

Driven by a passion for innovation, adventure and purposeful design, we build equipment that delivers more capability with less weight, less space and less complexity.

Made in Australia. Built to last. Supported for the long haul.

Less clutter. Less waste. More capability.

One unit, not three boxes

Less to wire and less to configure. Designed and built in Australia, for Australian conditions.

Made to wear the miles

The steel cases take the knocks and rigours of real use. Scratches become a patina that tells the story of where you have been. Inside, everything is engineered and in its rightful place.

Made here, supported here
