⚓ Marine Battery Systems – Townsville Wholesale Batteries

When you’re on the water, a flat battery isn’t just inconvenient—it can leave you stranded. At Townsville Wholesale Batteries, we supply and install marine battery systems designed for everything from small creek boats to large marina vessels. With trusted brands, professional advice, and the right setup for your needs, we’ll keep you powered safely and reliably.

Small Boats & Creek Runners

For tinnies, small creek boats, and day boats, a dual-purpose starting battery is often the best solution. These batteries provide enough cranking power to start your outboard, while also supplying steady power for lights, sounders, and small accessories.

  • Compact, reliable batteries that do double duty.

  • Easy installation and affordable solutions for weekend fishers.

  • Marine-rated for vibration and water resistance.

House & Start Battery Systems

For larger boats that run accessories like sounders, radios, live wells, fridges, and lighting, it’s best to separate your batteries into house and start banks.

  • Starting Batteries – deliver high cranking amps to start your motor reliably.

  • House Batteries – deep-cycle AGM or lithium options to power accessories.

  • Battery Isolators & Management Systems – automatically protect your starting battery from being drained, so you’re never left stuck on the water.
