There’s nothing quite like a flat battery to put a damper on your off grid adventure. That’s where a dual battery isolator, kit or relay comes into play. These units are designed to separate your starter battery and auxiliary battery to prevent your starter battery from being drained when your vehicle engine is off.

Should I Buy A Dual Battery Isolator Or A Combiner?

Choosing between a dual battery isolator and a combiner depends on the application. An isolator is used for allowing one charge source to charge multiple batteries at once without connecting the batteries together. A combiner on the other is ideal for powering a critical load from two batteries in the chance one fails.
