The reason I suggested going to the battery switch for NOW is that I assume for your future needs you will want to simply wire ONLY to the house bank which requires a charger with ONLY one output. MOST chargers have only one output and it is WRONG to buy one with more outputs than you need especially since many multiple output units will DIVIDE the total amps between the outputs so that one set of batteries will never get the full amperage you paid for. A 20 amp dual output charger may thus only give 10 amps max to each of two banks. Not what YOU want or need.
Thus...if you get a single output unit for your future needs...you must hook it up temporarily to the battery switch to be able to charge both batts you now have until you get the echo charge.
Thanks Cam, that makes a lot of sense. I'm still just scoping out chargers. It seemed that most chargers that have multi-stage charging and the ability to select the battery type also had multiple outputs. I will keep looking though. I don't want to spend any more $ than I have to.

By the way, is it totally weird that this boat doesn't have a battery charger? My surveyor said it's not THAT strange, and certainly possible it was an "option" back in 1984. I'm just curious.

Here's my $.02.

I used a ProMariner dual bank charger. You can pick them up for under $200 at Bass Pro Shops. They also make a 3 bank if you prefer to put your starter battery on a 3rd bank instead of combining it on one of the existing ones.

Here's the link:

Jos—

Highly recommend you replace the AC panel with this one, shown below. You want an Shorepower AC panel that has a dual breaker so that it breaks both the hot and neutral lines. If you don't do this, and your boat is plugged into a shorepower post that has reversed polarity, you can end up dead, cause you think you shut the AC off, but the AC will still be hot.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Good point, sailingdog. For now, I'll be sticking with the standard stuff on the boat, but I do see your point re: safety. Eventually we may end up replacing several of the electrical panels. For now, I'll be sure to consider the "MAIN BREAKER" off switch to simply mean that nothing is turned on, but that there is STILL POWER.
Thanks!

What happens when you only have all you batteries connected in one bank and one of them is weaker or fails. Doesnt that drag down the whole bank. Isnt that people use the mutiple bank method?

True, but that is why you're supposed to replace the entire bank at a single time. You really shouldn't split the house battery bank, since that makes the house bank effectively smaller. Two 200 amp-hour banks don't last as long as a single 400 amp-hour battery bank due to the Peukert factor.

Yeah, our main thing is that we do not feel the need to carry twice as many batteries as needed, just so each bank can be the same. We need one big house bank, and one battery to start. We may use the same type of battery for starting as well as house, but the number of them will be different. Minimum two for house (right now I only have one), and perhaps more if I can figure out where to put them.

We are seperated into two banks. Small charging one with a sealed group 31 glassmat and a large house bank with 4 105 trojan 6 volts. Yes Saildog, that old Peurkeut factor. Sorry I didnt mean to imply to set up two equal banks,,that would be a waste. That why we still have that other in reserve to start the motor or to limp home on.

That's more along the lines of what we'd be looking to do. Single battery in one bank for starting, then a "pile o'batteries" in the other for house. I don't know if we'd have room for 4 trojans, so we might have to stick with 2 12v batteries for house. In fact, I'm not even sure where we'll add the starting battery--right now, there's only room in the battery compartment for the 2 batteries we have now. Hmmmm....We'll figure that one out, I'm sure. We can't be the only people in the world to add a 3rd battery to a Sabre 34 Mk I!

Chef...you never want to combine an AGM starter with Flooded House. One or the other will be getting the wrong charging regimen. Are your 6V's also AGM???
