Blue Seas Add-A-Battery Kit 65A

The ADD-A-BATTERY is as simple to operate as an ON-OFF switch, yet effectively manages the switching and charging of two batteries from a single charge source

The Add-A-Battery includes a Dual Circuit Plus™ Battery Switch and an Automatic Charging Relay. These components simplify switching and automate charging, so that all you have to do is turn the battery switch ON when you arrive and OFF when you leave.

Dual Circuit Plus™ Battery Switch

Simplifies switching

Isolates engine and house circuits

Combines batteries for emergency starting

Tin-plated copper studs for maximum conductivity and corrosion resistance

ACR Automatic Charging Relay

Automatically combines batteries during charging

Isolates batteries during engine cranking and when not charging

Shares the charge between two batteries more efficiently than a battery isolator

7601 Charging Relay:

• The Mini Automatic Charging Relay (M-ACR) is designed to manage the charging current from alternators up to 65 Amps found on most outboards and many inboard engines.
• Start Isolation (SI) protects sensitive electronics by temporarily isolating house loads from the engine circuit during engine cranking, protecting the house circuit from voltage sags and spikes.
• The compact design allows for three mounting styles: surface, rear, or panel mount. The M-ACR is also available as a module in a Custom 360 Panel.
• Features

Frequently Asked Questions

• What is the Blue Sea Systems ADD-A-BATTERY kit used for? The Blue Sea Systems ADD-A-BATTERY kit manages the switching and charging of two batteries from a single charge source. It includes a Dual Circuit Plus Battery Switch and an Automatic Charging Relay to simplify battery switching and automate charging.
• How does the Dual Circuit Plus Battery Switch work in the ADD-A-BATTERY system? The Dual Circuit Plus Battery Switch isolates the engine and house circuits, combines batteries for emergency starting, and simplifies battery switching. Its make-before-break contact design allows switching between battery banks without power interruption.
• How does the Automatic Charging Relay manage two batteries? The Automatic Charging Relay automatically combines batteries during charging and isolates them during engine cranking and when they are not charging. It is designed to share charging between two batteries more efficiently than a battery isolator.
• What is the Blue Sea Systems 7601 Mini Automatic Charging Relay designed for? The 7601 Mini Automatic Charging Relay is designed to manage charging current from alternators up to 65 amps found on most outboards and many inboard engines. It senses charging on two battery banks and includes an LED to indicate ACR status.
• What is the Start Isolation feature on the Mini Automatic Charging Relay? Start Isolation temporarily isolates house loads from the engine circuit during engine cranking. According to the product description, this protects the house circuit from voltage sags and spikes during engine starting.
• What mounting and environmental features does the Mini Automatic Charging Relay have? The Mini Automatic Charging Relay supports surface, rear, or panel mounting. It has a pull-off and snap-on insulating cover, a 1/4-inch x .032-inch male quick-connect ground terminal, and an IP67 waterproof rating for temporary immersion.
