Automotive

An automotive battery isolator is a device used in vehicles to manage multiple batteries, typically by isolating the starter battery from auxiliary batteries. Its main purpose is to ensure that the starter battery is never drained by accessories or additional loads, like lights, fridges, or inverters, which are connected to auxiliary batteries.

  • RVs & campers: Powering lights, fridges, and other devices off an auxiliary battery without draining the starting battery.
  • Boats: Running electronics and bilge pumps separately.
  • Off-road/4WD vehicles: Supporting winches, compressors, or camping gear.

Overall, it enhances battery performance, extends battery life, and provides peace of mind when using electrical accessories away from a power source.
