Additional Information
The Add-A-Battery System comes with a Dual Circuit Plus Battery Switch and 120 Amp Automatic Charging Relay. The Dual Circuit Plus Battery Switch switches two battery banks simultaneously with one simple on/off switch, while still maintaining battery bank isolation and minimizing the risk of a dead start battery. The "Combine Batteries" function offers the ability to combine two battery banks in the event of a low start battery. Case can be surface or rear panel mount. Features 3/8" 16 tin-plated copper studs for maximum conductivity and corrosion resistance. The "Starting Isolation" Automatic Relay allows temporary isolation of house loads from engine circuit during engine cranking to protect sensitive electronics. Supports high-output alternators up to 120 amps. Built-in LED light indicates when batteries are combined. Waterproof rated IP67.

Rated 4 out of 5 by from looks to be good quality Looks to be a good product from initial un boxing. You will need to get ss screws to install the switch as they are not provided. I am familiar with dc circuits but someone who is not may want to have someone explain it to them. not to difficult buy applications may differ from the provided diagram.You also have to factor in the cost of new battery cables.

Rated 5 out of 5 by from Worked as advertised Have to understand that you only get the part. We had to design and install a support board so that we could mount this on the boat. Eeded a "few" other parts (wires cables etc) to complete the installation
