Blue Sea Dual Circuit Add A Battery Kit

Don't get strandard, add a battery! Adding a second battery to the electrical system prevents the unintended discharge of the engine start battery. Blue Sea Systems Add-A-Battery Kit 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 Kit includes a Dual Circuit Plus Battery Switch and an Automartic Charging Relay. These two components simplify switching and automate charging, so all you have to do is turn the battery switch on when you arrive, and turn it off when you leave.

Dual Circuit Plus Battery Switch Features:
Combines batteries for emergency starting.
Isolates engine and house circuits.
Simplifies switching.
Tin-plated copper studs for maximum conductivity and corrosion resistance.

ACR Automatic Charging Relay:
Allows efficient dual battery charging without the need for regular adjustment or rewiring.
Automatically combines batteries during charging.
Isolates batteries during engine cranking and when they're not charging.
Shares the charge between two batteries more efficiently than a battery isolator.
