    (39)94 2452 Battery Charger-gctid358066

    Looking for best and easiest location for the charger, boat doesn't have one now. Pics if you have them. 3 Bank system. Thanks, Dave

    I had installed a Guest waterproof charger (2 banks, 20 amps) on my 2452 right above the batteries in the port side lazarette. My kicker bracket mounting plate is just above the scuppers, so the 6 bolts were protruding about 1.5" through the transom and backing plate into the lazarette space. I had mounted two aluminum channels to these bolts, drilled the holes for the charger, and mounted it to the channels. Works great, it is close to the batteries, and I can see the led lights on the charger when I open the lazarette.

      Thanks fishaman, How did or where did you run the power to the charger?

        Dave, why a 3 bank charger on this size boat?

        You really need a only a single dedicated cranking battery (#1 MBSS position) and a HLBB (#2 MBSS position).

        Just curious.

        Assuming that your boat is equipped with S/P, I'd suggest using an open circuit in your panel making this a permanent A/C connection.

        Take the charge leads to the rear #1 and #2 terminals of your MBSS, also making these permanent connections, avoiding the Rat's Nest and small terminal corrosion potential at your batteries.

        Take the charger Negative lead to a system negative engine connection.

        This not only avoids the Rat's Nest, but without these making direct battery connections, R&R'ing batteries will pose less confusion as to what's this/where does this go?

          on my 93 it is installed under the port cockpit seat, the same side has the shore power plug, just under the port cockpit/hardtop window, makes a run to the breaker panel in the cabin then back to the charger

            3 bank because, 1 start and 2 house batteries. Boat does not have factory fuse box. If it doesn't work out I'll stick with just 2. I know what your saying on rat's nest but the house are not in the same compartment as start battery. Do have shore power but only a dealer set up. At least this gives me some good ideas. Won't be able to get to the boat for another 1month or so. Will entertain all suggestions, keep them coming. Thanks, to everyone. Dave

              Dave, IMO, two House Batteries will not serve you as well as if this was one large House Bank of "like" batteries.

              When you divide these, you'll very likely find yourself drawing them each down below 50% much sooner than if it were one large bank.

              By increasing the depth of each cycle, you will inadvertently shorten their life span.

              A good 2 bank O/B smart charger will do you just fine.

              You may even find that the savings from the 3 bank to a 2 bank, will allow for a higher amp 2 bank charger.

              Just say'n!

              Your call!

                Originally, I did not have the shorepower on my boat. So, before the charger, I have installed the receptacle, and a 125 v panel with breakers for fridge, stove, outlets, etc. One of the circuits is used only for charger, I run the wire along the port side to the lazarette, and connect the charger to batteries via MBSS the way Rick says.

                  I understand now what you are saying on a larger house battery. Wish I had my 28 or 32 Bay back. I think I'll go that way. Thanks again, Dave

                    Just wire your 2 house batteries in parallel and bingo... 1 big house battery. Then wire your switch and charger for the 2 banks. No need to separate the house batteries...

                      That was what I was going to do. Maybe I didn't explain it well. Still deciding.

                        Dave, one of us can explain the Amp Hour capacity issue (2 separate banks -vs- 1 large bank) if need be.

                        But both you and you House Bank will be much happier if you group the two together (making one larger bank), and then use a 2 bank charger.

                          Just talked to a fellow who distributes batteries in my area. He said do a large house or parrallel 2. You are right Rick to use a 2 bank charger. Taking 3 bank back today and going with a 20 amp 10/10 2 stage. Thanks,Dave

                            Read the data carefully. Some chargers that advertise 20 amp 10/10 2, are actually only 10 amp per bank. 10 amps is not very much.

                              Be a little careful here. They should be the same type, size and age if you are going to parallel them. A new battery with an old battery should not be connected together.
