Dual Battery Systems in Batemans Bay
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 Batemans Bay and the surrounding Eurobodalla, NSW South Coast — including Catalina, Surf Beach, Sunshine Bay, Long Beach. Regular weekly trips from Canberra. Bookings welcome at homes, holiday parks and storage yards.

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.
Can you come to a caravan park in Batemans Bay?
Yes — caravan park callouts are a big part of what we do on the coast. Just have your site number ready.
How often are you on the South Coast?
Weekly, usually mid-week — call ahead and we’ll line up your job with the next trip down.
