What We Do

Power Your Adventures
Without Compromise

A dual battery system lets you run your 12V accessories — fridges, LED lighting, compressors, inverters and more — off a dedicated secondary battery while keeping your starter battery fully isolated and ready to go. Whether you're heading into the bush for a weekend or doing serious long-range touring, we'll design and install the right setup for your vehicle and your needs.

At Ignition ASV we've been fitting dual battery systems across the Goulburn Valley for years. We use quality components from trusted brands and make sure every system is properly wired, fused, and rated for your load requirements — not just a generic kit thrown together.

DC-DC chargers — intelligent charging from your alternator, compatible with AGM, gel and lithium batteries

Battery selection — AGM, deep cycle or lithium (LiFePO4) depending on your budget and power needs

Anderson plugs — clean external connection points for fridges, compressors and caravan hookups

Inverters — convert 12V DC to 240V AC for running laptops, power tools and appliances on the go

Solar input — keep the auxiliary battery topped up when parked in camp

Full professional wiring — proper cable sizing, fusing and terminations — done once, done right

Common Questions

Dual Battery FAQs

If you run a 12V fridge, camp lighting, a compressor, or plan to charge devices off-grid overnight, then yes — a dual battery system will protect your starter battery and give you reliable power without worry. Running a fridge off your starter battery for even one night is a recipe for a flat battery in the morning.

AGM batteries are affordable, proven and work well for most recreational touring setups. Lithium (LiFePO4) batteries are lighter, hold more usable capacity and charge faster — they're worth the extra cost if you tour regularly or run heavy loads. We'll help you choose based on your budget and how you use the vehicle.

Absolutely — and it's often cheaper to do it in one go. We can install a roof-mounted panel or set up a blanket/portable input at the same time as the dual battery system. A quality DC-DC charger like the REDARC BCDC can accept both alternator and solar input simultaneously.

A professionally installed dual battery system will not void your vehicle warranty under Australian consumer law (ACCC guidelines). We use correct cable sizing and fusing and keep our installation separate from factory wiring. If your dealer says otherwise, that's incorrect — installations must be proven to cause a specific fault before warranty can be denied.

A standard AGM dual battery install with DC-DC charger typically takes 3–5 hours. More complex systems with lithium, solar and multiple outputs can take a full day or more. We'll give you a confirmed timeframe when you book so you can plan around it.
