    Comments about Blue Sea Systems Add-A-Battery" Dual Circuit Syste:

    I am so glad I purchased the Add-a-battery. I can sit out on the lake and play my stereo and have the cockpit lights on and not worry about my boat not starting. It was really easy to install. I did it all myself and just read the manual. Pretty simple. I had to make a couple trips to west marina to get the right cables and terminal adapters but that's typical for me. I tend to not look over everything before I dig in. If you're smart you'll assess everything first and then buy what you need to save yourself an extra trip or two.

    Good Concept But...

        Comments about Blue Sea Systems Add-A-Battery" Dual Circuit Syste:

        This is a good concept but it is still lacking. I will say that it does warn of the potential problem that it will create. In my case I have a 21 foot center console. I rewired the entire boat, relocated the batteries, install new lights, stereo, VHF radio, switch panel, circuit breakers, etc, etc, etc. I found this battery switch and thought it would be a good idea, keep the batteries separate and it charges based on priority and needs. The problem is that the little brain box of this thing draws enough current, even though everything else is shut off, to drain a new fully charged Group 31 battery in about a month. It does warn of this and says that you may install a special switch to shut the brain box off completely but who wants to have to remember another switch. I removed this and just installed a good old fashioned two battery switch. If they could design it so that when you switch it to off that it kills everything then it would probably be great but as it is, not so much. I can remember to switch my batteries back and forth to keep them charged.

          Comments about Blue Sea Systems Add-A-Battery" Dual Circuit Syste:

          I really belive everyone should have one of these on their boat. This is priced well below other battery isolation products and is a quality product. The instructions are probably not specific enough for someone with no knowledge of circuits to understand as they are somewhat generic.

          Pictured on the photo is how I mounted the batter switch, I couldn't find a picture of one flush mounted on the net, I was really pleased with how this came out versus miunting it on the surface.

          A tip that I used: The instructions tell you to run the postive (B) cable from the Relay to the house battery. Being as my switch and relay were mounted very close to each other and my battery was approx 6 feet away, I chose to use the "power-in" post on the battery switch as a junction connecting the B side of the relay to the "power-in" side of the battery switch for the house battery, so I only had to run 1 cable from the battery to the switch. This saved me from having to buy a $30 cable.

              Comments about Blue Sea Systems Add-A-Battery" Dual Circuit Syste:

              Don't let the higher rice steer you away, these devices work and have saved several batteries in boats I take care of. Example: Auto bilge pump runs the house battery until dead, start battery is protected. Allows you to wire the entire system so that all devices are on bus bars and the batteries have just cables. Off is really off.

              Comments about Blue Sea Systems Add-A-Battery" Dual Circuit Syste:

              This product ends the worry about draining your battery with radios, sounders, etc while fishing. It isolates the "house" battery from the "start" battery but keeps them both charged from a single engine.

              It does require some knowledge of DC circuits to install, but a careful reading of the instructions and some help from the West Advisor will get the job done.
