OK Here's a stupid question.

When using multiple 6 volt bats they are series-wired in pairs for 12 volts
then the pairs are parallel wired to build the bank. Would that be correct?
Do you use isolation switches within the bank?

What is the gain? I have not researched the amperage of the 6 volt bats
ver's size. Is there truly an advantage to doing this?

Jim, We have been using standard 6 volt golf cart batteries that we
bought from a golf cart service guy in Marathon Florida on both of our
house banks. Cost was around 60 or 70 dollars each. We do a lot of
cruising and the batteries are discharged and recharged quite a bit via
the engine, solar panels and wind generator. Batteries last and average
of seven years before they start to wind down and we replace them. be
sure and use all of the same batteries. Don't mix and match different
manufacturers. Chuck

On my trawler my present house battery bank consists of two 8Ds, my
starting battery is a 4D.

The 8Ds are ready for replacement. I'd like to go with golf cart
batteries.

Costco has them for $62 each. No real information on the card in the
store. West marine has them for $127. There is not enough information in
either place to compare them to each other.

Several sites on the Internet have Trojan golf cart batteries, and there
are many choices, for prices that look like $200 and up.

I have a lot to learn about batteries. I don't have enough information,
yet, to compare what I'm seeing.

Then there's the issue of a new "Smart" charger. My 20 year old charger
probably needs to be upgraded with the batteries.

Your input would be appreciated.
