If you use 6 volt batteries which are the size of the golf cart type, you should be able to get them in the standard battery box under the quarter berth. If you decide to move them, I would suggest that you keep them in the center of the vessel and away from the ends of the boat. I removed the drawer and the alcohol tank in the main saloon settee and made a battery box which is large enough to hold six golf cart batteries or two 8D 12 volt batteries.
<div>Robert, In around 1990, I installed four 6-volt golf cart batteries as my house battery bank, and one 12 volt starting battery as the engine battery. The golf cart batteries were rated at 220 amp hours each or 220 amp hours at 12 volts for two wire in series. With two sets of two batteries wired in series and wired together in parallel, I get 440 amp hours out of the house bank. This is quite sufficient to operate our refrigeration and inverter for the length of time that we need to anchor out. Initially we had quite a time charging this set up, though. Since then I am contemplating, although I have yet to install, a higher amperage alternator (say 100 amps) and a three step, higher capacity regulator! I have the entire set up in the original battery box area under the quarter berth. That's five batteries total! It's a tight fit and the 6 volt batteries need to be on the inboard side due to their height. Good luck. Mick MacMullan

Robert,
I just had Jack Rabbit install 4 125ah type 31 batteries in the larger compartment under the quarter berth. Thats 500ah as the house bank. Aft of that compartment is a smaller compartment. They installed a 125ah starter battery there. Grand total of 625ah plus 125ah alt/reg & link system. It all fits just fine.

Robert,
Good question. I don't remember. I had it done in late December. I was aboard the end of January, and charged the system through the onboard charger. I did not take note of the layout of the batteries, other then they looked impressive and were nicely installed.
Not being a gadget person I went for the Link 10 plus a toggle switch to check the starter battery. It may have been a mistake. My only purpose for the extra amp hrs. and the 125 ah alt/reg was to be able to run my Adler Barber refridgeration, and not have to run my engine for two or three hours to replace the amp hrs. I don't want to be a slave to the batteries, and I am not going to change the way I cruise. If there is wind I am going sailing (without running the engine). If I am not treating the batteries right, I will replace them more often. The important thing for me is not loading 100lbs or 150lbs of ice in the box, which is what I have been doing.
Southerly is located at Orienta YC, in Mamaroneck, NY. If you are in driving distance I would be glad to show you the installation.

Bob,
My M382 came from the factory with four standard 12V batteries (group 27?), and they all fit just fine -- 3 side by side (inboard) and one across the ends (outboard). I believe the total capacity was somewhat less than 300 A-h. Since the practical useable capacity of such a bank is in the neighborhood of 90 A-h, like you, I opted for a larger house bank.
As an aside, one limiting factor for installing larger capacity batteries is their height. I added six, 6-Volt, AGM type, golf cart batteries in this same area, but I first had to raise the bottom of the quarterberth. In hindsight, I probably should have looked for a better location since the batteries weigh 75 pounds each and "Aurora" now has a 2 degree list to starboard. I have two more of these same batteries to install as a starting battery, but they now must go as far to port as possible so the lever arm can help fix the trim. It should all work out OK, but it's a nuisance. The 600 A-h house bank is fed by a new 150 Amp Balmar that is controlled/monitored by a Link 2000-R. The engine battery will be maintained by the engine's original alternator. I found a really slick "DC Parallel Panel" by Blue sea to distribute the power. Besides providing an on/off switch for the engine battery and a 100 Amp breaker for the DC house panel, this nifty little panel also has a paralleling switch to join the two banks.
With all this weight and capacity, "Aurora" is obviously a long range cruising boat. IMHO, the battery location suggested by Jay seems like a good one and is well worth considering. Wish I would have thought of it!
Good luck with your upgrade.

Xanadu is a 384 hull #49 I have 4 Trojan T-105's( 6 volt) installed under the quarterberth, I put in 4 small battery trays to position them, the aft two athwartships and the forward two fore and aft. The front athwartship battery has to come out first or go in last to make it work. I have 1/8th inch clearance on top . Good luck Ron
