Not sure which type of Dual Battery System is going to suit your vehicle? 

Your vehicle is one of the main factors when deciding what type of dual battery systems to get.  Some of our most popular options include: 

We can also install custom systems into caravans, camper trailers and motor homes to suit a wide range of applications, including free camping, off-grid travel and full-time touring.

There are also different levels of systems available. The simplest system usually includes a battery isolator to protect the starting battery from being drained.

The next level up is usually a DC-DC charger which handles the charging of the auxiliary battery while also protecting your starting battery. This is also commonly used on vehicles that have an electronically regulated alternator.

At the top end of the scale is systems that include a battery management system. These are most commonly found in caravans and larger battery systems but they can also be modified to suit vehicle setups as well.
