Times are changing and obviously so is Technology.

20 yrs ago when I had a 28 ft. Chris Craft Cavalier, I had 4-8D's for
all accessories, and a cheap car battery for starting, down in the
belly of the beast., I made my own battery isolator, adn the starting
bat. was independant. the 4 Cat 8D's did all the acessory power. We
spent weekends on the boat without firing up for recharge.

I didn't have any complaints with the system, and would do it again if
I had a similar craft. BUT, your situation is obviously different.

I wasn't aware that some companies made individual cell batteries, but
that makes sense, and is good to know that you can make your own custom
charging system to fit your needs, PLUS, be able to stuff individual
cells in empty space.

Good idea.

Whats the matter with going back to 8-D's?

Golf cart batteries should/might be cheaper, easier to handle, take less
room, have more amps, and be better suited to the task.

That's why.





That's why....Rolls offers the single cell configuration. You bolt 6
(nominally) 2-volt
batteries (cells) together in an 8D case. Each cell weighs something
around 30 pounds, so that's all you need to handle at a any one time.
If the battery appears to fail, it will very likely be just a single
cell that has gone bad so instead of buying a whole new battery you
only have to buy one cell. Of course you won't have to buy anything for
7 years, as the first 7 years of the 10-year warranty are full
replacement coverage without any pro-rated adjustments.

Have you checked the ratings of a Rolls 8D vs. a pair of Walmart golf
cart batteries?
You might be surprised.

We have four battery systems on our boat, and one of them powers an AC
inverter. We do use golf cart batteries for that application, but only
because of a lack of available space to use an Rolls 8D.
