Battery Switches by KanSmart. Details:What Is A Battery Isolator? Battery isolator systems allow you to charge the secondary batteries in your van when the motor is running. There are many variations of hooking a system up, but they all share one common goal: to “isolate” your secondary battery so that when you’re running all of your electronics you don’t drain the starter battery. Lengthen the Life your Batteries When two vehicle batteries are wired in parallel they have a tendency to charge and drain one another. Installing a relay that disconnects the batteries when the engine is off prevents excessive wear and lengthens the life of the batteries.
