Ok I am thinking of adding two 6 volt batteries for my stereo. My question is has anyone ever ran 8 volt batteries? Most stereo equipment is rated at 14.6 volts so I don't think that it would hurt.

Two 8 volts would give you 16 volts and would cause all kinds of electrical problems. I'm not sure how your alternator would react either, my guess would be...not good. Stick with the 6v.
I think the 8v's are for 24v systems.

I was thinking a completely isolated bank just for the stereo.

You really can't do the 8 volt batteries because you have no practical way to charge them up to or maintain them at 16 plus volts. If you do not charge the batteries fully, then degradation will be accelerated.

IMO, the golf cart batteries are the way to go if you don't mind the weight. I've used them in my motor home for years and they will easy outlast any deep cycle battery. They like to be discharged slow and recharged slow. Costco has golf cart batteries for $90.

I know i was so pissed when i saw Costco had them, but to my surprise they only stock one at my costco and they wouldn't order me 2? WTH?

So fare i really like the batteries, as you mentioned on weight, yea they weigh a ton, Soo much so between the 3 batteries i have and my 4 amps, the boat is 300 lbs heavier on my Port side and actually leans a little in the water, so i have to compensate this weight when people want to wake board.

Its also messing more with the Goofy side surf because Goofy side doesnt like any counter weight at all.
Reguar side is slamming though LOL

Each Costco has different inventories on those batteries so you need to check other stores. I don't think they are as good as the Trojan batteries I used but they jumped in price a lot.

I'm not sure if mine are the same size as the Costco ones eigher, these ones are pretty big.

This is the specs on them. Mine are the 2400

I just use the Pro Sport 20 hooked up as a 12v. I get home and at the advise of Dave with Earmark, i turn my ACR system to OFF and plug in the charger, this way it charges the 2 6V batteris <as 12v> and then the house seperate.

When running the boat i let the ACR do the work.

Just remember hook 1 positive term of 1 battery to the Negative of the other battery, and then pretend those two posts don't exist. Don't hook anything else to those 2 posts.

Then your golden LOL

Ok I am going to run them completely independent of the boats charging system and just charge them while at home.

That works too, i"d suggest just making sure the home charger has a computer to sense the voltage/amperage requirements, and slow charge them. I tend to just leave the boat plugged in as much as possible at home but sometimes i get lazy and forget for a few days LOL

Just ordered a ProMariner 20 - amp ProSport Gen 2 Battery Charger (2 - bank; 12/24V) I want to make the batteries and charger removable in case I buy a new boat in the near future.

This what i got off the internet for the Costco GC2 that are made by Johnson Controls.
GC2 US Battery Red Top:
Amp-Hour at the 20 hour rate: 220 Ah
Minutes at 75 amps: 110 minutes
Minutes at 25 amps: 425 minutes

I also like "Battery Tender" chargers and use them for my smaller batteries. They don't overcharge.

Buy the $5 handle to move 6v batteries around if they don't come with one!
