An automatic charge relay designed for boats with outboards and small inboard engines.

If you are adding a second battery to support a larger stereo, a trolling motor or a new fishfinder, an automatic charge relay (ACR) is a great way to manage the additional battery and protect the equipment it powers.

The Blue Sea Systems mini ACR is designed to be used with alternators commonly installed on outboard engines and smaller inboard engines equipped with 65 amp or less alternators.

The ACR combines the two batteries while charging, and isolates the house battery to protect sensitive electronics while starting the engine. It will share the charging source more efficiently than a battery isolator without creating a voltage drop.

Additional wiring or an external regulator is not required and makes installation straightforward. Because the ACR is ignition protected, it can be installed within the engine room.
