Smart battery isolator


Prevents loads on auxiliary battery from draining the starting battery

Ideal for dual battery applications, Cole Hersee’s Smart Battery Isolator prevents loads on the auxiliary battery from draining the starting battery.

The Smart Battery Isolator provides a more flexible solution than traditional isolators, as it is not specific to an alternator type. It’s also smaller, lighter and generates less heat than competitive products.

Because 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, there is lower strain on expensive charging components, extending the product life.

No diode efficiency losses occur when using Cole Hersee’s smart battery isolator, and it also allows bi-directional charging from alternator or from other power chargers/converters.

Easy to install, the smart battery isolator also features an LED status indicator and operational start assist.

The Smart Battery Isolator is available in 85A (48525) and 200A (48530) versions.
