Mini Automatic Charging Relay – 7601
This Automatic Charging Relay (ACR) by Blue Sea, keeps allows automatic battery management through intelligent voltage sensing.
When connected our ACR will insure the start battery is completely topped off, and only then will allow the alternator to begin charging the house battery.
It features automatic under voltage lockout and start isolation to protect your boat’s electrical system.
With the installation of this device you’ll no longer have to constantly be tinkering with the battery switch to select which battery your alternator is charging.
