Adding a second battery to the electrical system prevents the unintended discharge of the engine start battery. Blue Sea Systems popular Add-A-Battery kit was primarily designed for boats with alternator output of 120A or less. When installed, the Add-A-Battery isolates the start battery from the house loads which prevents the discharge of the start battery. The Add-A-Battery offers a simple way to control the charging and battery switching of two battery banks. The E-Series Dual Circuit Plus Battery Switch simplifies the switching while the SI-ACR automates charging between two batteries.

Allows two batteries to be efficiently charged from a single charging source without external regulators or isolators
Automatically isolates house battery during starts to protect electronics
Provides an emergency combine feature to draw power from both batteries
Simplifies switching for two battery systems
Tin plated copper studs on the battery switch provide maximum conductivity and corrosion resistance
