12V Battery Isolators

A 12V battery isolator is an electrical device designed to manage multiple batteries in a vehicle’s electrical system. 12V battery isolators serve the purpose of preventing the discharge of one battery into another, ensuring that the starter battery remains isolated from any auxiliary batteries used to power additional accessories.
A 12V battery isolator becomes especially valuable in camping, caravanning and 4WD applications, because it allows the user to run accessories like 12V fridges, lights and other camping gear from the auxiliary batteries without the risk of flattening the vehicle’s starting battery. Many KickAss 12V battery isolators also come with integrated features such as automatic voltage sensing and smart charging capabilities, optimising the overall efficiency of your power setup.
