Cole Hersee’s Smart Battery Isolator 48525 and 48530 prevents loads on the auxiliary battery from draining the starting battery, the company says. The smart battery isolator provides a more flexible solution than traditional isolators, as it is not specific to an alternator type. Also, Cole Hersee’s smart battery isolator is smaller, lighter and generates less heat than competitive products, the company says.
