Dual Battery Systems in Canberra
Power that doesn’t flatten your starter.
A properly built dual battery setup is the difference between a great trip and a long walk for help. We install dual battery systems that keep your fridge running, your lights on and your starter battery untouched — using only proven brands like Redarc, Projecta and Enerdrive.
We bring this service to Canberra and the surrounding Australian Capital Territory — including Belconnen, Gungahlin, Tuggeranong, Woden. Based locally to Canberra, with weekly trips down to the South Coast.

- DC-DC chargers with solar input (Redarc BCDC, Projecta IDC)

Common Questions
AGM or lithium — which should I get?
Lithium gives you more usable capacity, lighter weight and faster charging — but costs more upfront. AGM is still excellent value if weight and space aren’t critical. We help you choose based on how you actually use the vehicle.
Do I need a DC-DC charger?
On any modern vehicle with a smart alternator — yes. Without one, your auxiliary battery will never reach full charge. We use Redarc BCDC and Projecta IDC chargers.
Can you fit a solar input too?
Yes — most DC-DC chargers we install include MPPT solar input as standard. Add a panel any time.
Do you come to all suburbs in Canberra?
Yes — we cover all of the ACT and Queanbeyan. Mobile service to your home, work or storage unit.
Where can you fit a 4WD build in Canberra?
We can do most jobs at your place if there’s undercover space. For bigger fit-outs we partner with workshops in Mitchell and Hume.
