Whether you are hitting local fire trails or planning remote off grid travel, your 4WD needs an electrical system that is safe, dependable and built to handle real adventure.
Twelve provides high quality 4WD electrical upgrades, dual battery systems, solar, accessories and air conditioning services across Port Macquarie and the Mid North Coast. We design every setup around how you drive, where you travel and the gear you rely on.
Below is an overview of the 4WD upgrades and electrical systems we install. Every job is completed by qualified auto electricians who focus on tidy workmanship, long term reliability and solutions that fit your touring style.
Upgrade your 4WD with practical and reliable accessories that improve safety, performance and everyday usability.
We install driving lights, LED light bars, UHF radios, reverse cameras, security systems, power sockets, USB outlets, compressors, fridges and more.
All accessories are chosen for durability and fitted neatly to integrate with your vehicle’s electrical system.
We supply and install high quality replacement car batteries suited to your vehicle and driving conditions.
From daily commuting to heavy off road work, we ensure your starting battery is the right type, correctly fitted and tested for dependable performance.
Lithium power is ideal for touring setups needing fast charging, reduced weight and high usable capacity.
We install 4WD lithium systems including under-bonnet rated options, canopy batteries and in-cabin setups.
Every system is supported with quality charging, monitoring and protection to ensure maximum lifespan and safety.
AGM batteries remain a reliable option for 4WD owners who want robust power at a more affordable price point.
We supply and install AGM batteries suited to fridge use, camping gear, winches and touring accessories.
Our team ensures proper mounting, ventilation and charging compatibility for safe operation.
A dual battery system is one of our most popular upgrades for 4WD owners—and for good reason. It allows you run a fridge, lights, a compressor, starlink, and charging your accessories all without risking a flat start battery. By isolating your starting battery from your second battery, it gives you the confidence that your vehicle will still start when it’s time to move on.
Each dual battery system is designed to suit each make and model of vehicle. This includes considerations such as battery location, battery tray, size of the DCDC charger along with the configuration & mounting of the 12V outlets. Our dual battery systems are typically a deep cycle battery or lithium battery depending on the location of the battery. The addition of a solar expansion point makes the system even more reliable so you can easily plug in your solar panel to keep your dual battery charged.
If you prefer a ready-to-go 12V solution, we offer pre-made kits designed and built by our team using high quality components.
Kits include battery boards, charging systems, inverter setups, accessory panels and canopy power solutions.
These can be shipped Australia-wide and installed at home or by your local auto electrician.
Reliable air conditioning is essential for both daily driving and long trips.
We provide A/C servicing, regassing, leak detection, diagnostics and repairs for all 4WD models.
Our ARC-certified technicians ensure your system runs cool, efficient and ready for the hottest conditions.
Solar power is a game changer for 4WD touring.
We install roof-mounted solar panels, portable panels, MPPT regulators and full solar systems designed to keep your batteries charged while you explore.
Every installation includes performance testing so your system delivers clean and efficient power when you need it most.
