Our Dual Battery Installation Services

Under Bonnet Installations
A 12V under bonnet dual battery system is a vehicle-installed setup designed to house a secondary battery under the bonnet. It’s commonly used in 4WDs, touring vehicles, and off-road setups to provide a reliable power source for accessories like fridges, lights, and other 12V gear—without draining the main battery. The system typically includes a battery and DC-DC charger to manage charging between the two batteries, ensuring the starter battery is always prioritized. It's a durable, space-saving solution ideal for permanent dual battery installations.

Behind Seat Installations

Frequently Asked Questions (FAQs)
Q: How long can I run a fridge on a dual battery system?
A: It depends on your battery size, fridge draw, and ambient temperature. For example, a 100Ah battery can run a 40L fridge for roughly 1–3 days without recharge.
Q: Is my vehicle suitable for an under-bonnet installation?
A: We’ll check your engine bay space. If it’s tight, we’ll recommend an in-cabin, tray, or canopy solution that works just as well.
Q: What maintenance is required for dual battery systems?
A: Regular checks include ensuring terminals are clean, connections are tight, and the system is charging correctly. AGM batteries need little maintenance, while lithium systems are often smart-monitored.
