Note that two 6-volt batteries in series (12 V) often provide more amp-hours
than a single 12-volt battery without having to worry about wiring up second
batteries (etc). I know a guy with two 6-volt golf-cart batteries in his
boat, put in for this reason (golf cart batteries appear to withstand
bouncing around a lot in a boat.)

Just got the latest Surplus Center catalog. If anyone wants a really
big bank they have a bunch of new Tyco rack mounted deep cycle gel
cells. 6V and 1450 AH for $300 each. They are built for large UPS
systems so I don't know how they would work in marine use and at 1500
lb. for a 12V bank you would need a pretty big boat but you would only
need to charge once every couple of weeks. :-)
