DUAL BATTERY SYSTEM
GET OFF GRID READY
Dual battery system
When you’re relying on your vehicle to power more than just driving, a properly set up dual battery system makes all the difference.
We install dual battery systems every week for customers who need reliable power for touring, work setups, and everyday use. Our systems are designed to keep your accessories running without risking your ability to start the vehicle.
Why Choose a Dual Battery System
A dual battery system gives you a separate power source for accessories like fridges, lights, and charging devices. We set these systems up so your main car battery is protected. You can run what you need without worrying about getting stranded with a flat battery.
For a lot of our customers, this is one of the most practical upgrades they make to their vehicle.
High-Capacity Batteries
Our high-capacity batteries are designed to deliver consistent and long-lasting power across a wide range of applications. Whether you’re running a fridge, lighting setup, or charging devices, you’ll have reliable energy when you need it most.
Intelligent Battery Management Systems
Our battery management systems (BMS) monitor charging and discharging in real time.
They help distribute power efficiently, protect your batteries, and extend overall system lifespan.
Heavy-Duty Wiring Kits
We use durable, high-quality wiring kits built for demanding conditions.
These ensure stable connections and safe power delivery across your entire system.
Battery Isolators and Solenoids
Battery isolators protect your main car battery by separating it from the secondary system.
This ensures your vehicle always starts, even after extended accessory use.
We don’t just supply parts. We install complete systems that are built to suit your vehicle and how you use it.
Our team works on a wide range of vehicles including Hilux, Ranger, Prado, and other 12V setups. We take the time to plan the layout properly, mount everything securely, and wire it the way it should be done.
When we install a dual battery system, it is done with long-term reliability in mind.
