The Smart Battery Isolator prevents loads on the auxiliary battery from draining the starting battery. Available in 85A and 200A versions, the isolator is smaller, lighter and generates less heat than other isolators, the company says. The device connects to the auxiliary battery after the primary battery is charged to 13.2 volts. It also allows bi-directional charging from the alternator or from other power chargers or converters and features an LED status indicator and operational start assist.
