replace 8 8 volt batteries for 50' Convertible w/ 8v92TI

If possible I would like to hear from anyone familiar with replacing the Rolls or comparable large 8 volt battery banks on 50' sport fish. I have heard golf cart batteries can work, but are they not deep cycle? and not capable of starting the 92's? Any info, suggestions, view points etc will be much appreciated andf thanks in advance

The standard flooded 19", 8V battery is no longer made by any mfg.
They still make the flooded 23" battery. If 8 of these will fit, problem solved in a most cost reduced purchase.

Once your heart starts beating normally from that cost estimate and still want to spend more money on maybe better quality batteries, then just go with the Rolls.

On a warm day, I would think 700 CCA per starter would be a good spec to start shopping with.

This post should be in the tech section but I used US. Batteries great service made in USA and a family owned company. They are made to compete with the Rolls only a lot less money and more available

The cost for eight 8v batteries is high enough that they should include a defibrillator at no extra charge.

You get that when you cross the wires. Lol

I think Fisheries Supply sells the US Battery but they are branded DYNO. If I recall, the battery factory is just down the street from them.

Their M13 provides 1000CCA.

You kids have been here before.

I usually start off numb (86 min proof) before I sign the credit card.
Then a pile of stuff from the wife for a while.

So far, my Frankenstein battery experiment (stage two) has been working. Some hick-ups but positive. More on this later when stage three is implemented later this year.
PM me if anybody wants any more details on these ideas.

Check my post in the Tech Talk Forum on Full River 8 V AGM batteries. I just did this on an LRC and did quite a bit of research.

I would recommend calling DC Batteries in Miami, they were a GREAT resource for me.

Do they have big flag terminals on them like the Rolls, US Battery, and Dyno? If not, you risk melting the terminals with the high amp loads of starting.

Anyone have experience with these:
