Power, performance, and peace of mind—done right.
When you’re deep into the bush or exploring the coast in your 4WD, the last thing you want to worry about is your power setup failing or an electrical issue bringing your trip to a halt. At Sandgate Auto Electrics, we understand how critical a reliable electrical system is for off-roaders, campers, and everyday adventurers.
That’s why 4WD owners across Brisbane trust us for dual battery setups, expert installations, and electrical fault-finding that actually solves the issue—not just masks it.
Dual Battery Setups That Work When You Need Them Most
Having a dual battery system isn’t just about convenience—it’s about freedom and reliability. Whether you’re running a fridge, powering lights at camp, or charging gear on the go, your auxiliary battery needs to be set up to match your specific needs.
We don’t believe in one-size-fits-all installs. Our team takes the time to understand how you use your vehicle and what you rely on out there. Then we design a dual battery solution that balances capacity, charging speed, and durability—whether you’re running lithium, AGM, or standard lead-acid batteries.
We also ensure correct isolation, clean wiring, and smart charging systems to protect your setup long-term.
For those running high-powered 12V setups or towing caravans, we also integrate DC-DC chargers, solar inputs, and monitoring systems for complete control of your power flow. This ensures your batteries stay healthy even during long idle periods or when driving shorter distances. Every connection, fuse, and cable is installed to handle real off-road conditions—heat, vibration, and dust—so you can focus on the adventure, not the wiring.
Electrical Fault-Finding Without the Guesswork
Electrical faults can be frustrating. Flickering lights, flat batteries, accessories cutting in and out—these issues are often caused by poor wiring, voltage drops, faulty relays, or grounding problems that are hard to trace without experience.
Our workshop uses advanced diagnostic tools to pinpoint the problem quickly and accurately. From 4WDs to work utes, we’ve built a reputation for solving faults that others miss.
We take the time to fix it properly, whether it’s a persistent battery drain, a charging issue, or an intermittent fault in your accessories. No guesswork. No shortcuts.
We can also test alternator output under load, verify charge profiles for lithium compatibility, and detect parasitic current draw that flattens batteries overnight—common issues after accessory installations or long-term use. These detailed checks help prevent unexpected breakdowns and protect expensive components like inverters, fridges, and comms gear.
Why 4WD Drivers Keep Coming Back
Our customers aren’t just here for a quick fix—they’re looking for long-term solutions that work in real-world conditions. That’s why tradies, tourers, and off-road enthusiasts from Brisbane and beyond continue to trust us.
We’re known for clean, professional installs, solid workmanship, and honest advice. If something doesn’t need replacing, we’ll tell you. And if it does, we’ll recommend what works—not just what’s popular.
Your 4WD’s electrical system is the backbone of everything you do off-grid. Powering your fridge, your comms, your lights—it all depends on smart design and reliable gear. That’s what we deliver.
