Dual Battery Systems

A dual battery system lets you run a fridge, lights, a compressor and charging gear at camp without draining the battery you need to start your vehicle. It's the foundation of any serious touring setup and one of the most popular upgrades for utes and 4WDs.
A typical setup includes an auxiliary battery, a way to charge it while you drive (such as a DC-DC charger), a battery tray or box, and the cabling and connectors to tie it all together. Browse the range below and check each listing for specifications and compatibility, or pair your system with one of our lithium batteries.
