Blue Sea 7649 Mini Add-A-Battery Kit - 65A 

 
Don’t get stranded – Add a Battery! Adding a second battery to the electrical system prevents the unintended discharge of the engine start battery. 
 
Blue Sea Systems smaller, more compact version of the popular Add-A-Battery kit was primarily designed for outboard powered boats with alternator output of 65A or less. 
 
When installed, the Mini Add-A-Battery isolates the start battery from the house loads which prevents the discharge of the start battery. The Mini Add-A-Battery offers a simple way to control the charging and battery switching of two battery banks. The M-Series Dual Circuit Plus™ Battery Switch simplifies the switching while the M-ACR automates charging between two batteries.

Included: m-Series Automatic Charging Relay - 12/24V DC 65A and m-Series Mini Dual Circuit Plus Battery Switch - Red

  • 65 Amp continuous rating manages the charging current from alternators up to 65 Amps found on most outboards and many inboard engines
