The Cole Hersee Smart Battery Isolator 48525 and 48530 prevents loads on the auxiliary battery from draining the starting battery. The smart battery isolator reduces charging system workload by not connecting to the auxiliary battery until the primary battery is charged to 13.2 V. A benefit of that reduction is lower strain on charging components. No diode efficiency losses occur when using the battery isolator, and it also allows bi-directional charging from alternator or from other power chargers/converters. The smart battery isolator features an LED status indicator and operational start assist.
