Yes that's what I feared. So by the time I rewire 6volts together and make a sealed box, plus add ventilation (regulated extractor fan?) it's probably a zero sum gain....Back to 12v AGM's for me!

Sorry for the delay.............

Yes..... 6v golf cart batteries. Trojan T-125. Four of them wired up in series/parallel which gives us 12V and 480AH of storage.

They weigh in at about 66 pounds each (I think). Its a good point others have made. It was a bit of work lugging the batteries aboard and positioning them. Definitely doable tho. Anything much heavier would be......... well a big time pain in the hinder.

Cheers.

Re: Golf Carts vs Deep Cycle Marine Batteries

We have 10-6v golf cart batt's for our house bank with pretty hefty loads. 150 amp/hrs/day sitting at anchor, 300 amp/hrs/day under way. Our Trojan T-125's lasted 5 yrs cruising 99% of the time, no marinas and never letting the bank go below 50% discharge or 12v. Replaced them in Aus. for 10 Exide brand golf cart batt's for $2200au!! I used to pay $52 ea , for Exide's here in So Cal as we are close to the manufacturer. Had 4 on a friends boat for 14 years!
If you call around, you can find good prices on 6 or more batteries.

Cheers, Greg

Re: Golf Carts vs Deep Cycle Marine Batteries

Is there not hydro caps available that will lessen water loss and reduce gassing for these types of batterys or are they only for some other type?

Hi embla,

I wonder why your AGM's lasted only 2 years. I just replaced my house bank (two 12V group 31 Deka AGM's) after 11 years. Inadequate size? Wiring or charging issues? Might be well to resolve this before installing another pair of expensive batteries.

Well to be honest I took the cheap route - the AGM's were allegedly Lucas BAGM100's but were only around £100 each at the time. I since learned (from the original supplier!) that they were Chinese batteries labelled as Lucas and no longer in business... Also I did note that my DuoGen charger was sometimes pushing out 15v at higher boat speeds, and so I am replacing the regulator. I had heard that these LVM regulators had been causing problems. So this time I am going for a better batteries - haven't quite decided between LifeLine and Elecsol and replacing the regulator with a Karasoul ICC50
