Dual Battery Isolator Installation Options
We supply and fit Dual Battery Isolators for 4×4’s, commercial vehicles, caravans and campervans.
Get the most out of your batteries with our state of the art dual battery isolators. Used primarily in 4WD and commercial vehicles, our dual battery isolators are designed to significantly extend battery life and safely charge your auxiliary battery. A good dual battery isolator works as a kind of rule-enforcer for battery systems. They allow DC power to flow through the isolator while forcing electricity to flow in only one direction. That way, when one battery in your bank is drained, it won’t end up pulling current from another.
