THOR battery Isolators can be used as a battery or circuit isolator to allow your alternator to charge more than one battery but keep your starting battery from being drained when the vehicle is not running. Isolate with Confidence.

The THOR battery Isolator is the perfect solution when adding a secondary battery to your vehicles electrical system. It allows the second battery to be fully dedicated to the power inverter. It does not create a voltage drop like common isolators tend to do. The isolator will draw less than 1 amp when your vehicle is powered On. All of this will ensure that your battery will be isolated with confidence!
