BLUE SEA MINI ADD A BATTERY KIT 65A
These include a Dual Circuit Plus™ Battery Switch and an Automatic Charging Relay simplifying switching & automate charging, so that you just turn the battery switch ON when you board and OFF when you leave.
Adding a second battery prevents getting stranded with a dead battery by isolating the start battery from the house loads that can quickly discharge a battery. The Add-A-Battery offers a simple way to control switching with the Dual Circuit Plus™ Battery Switch and automatically share a single source of charging between two batteries with the ACR.
