Never knew that. I'll have to research to satisfy my knowledge needs.
Well that was a very easy search. I guess 6V has higher AH and when in series to get 12V they retain that AH rating. Two 6V deep cycle batteries is $270 each and have 230AH which is significantly higher than my 1 12V at I think 120AH

It is really not that uncommon for boats to use golf cart batteries for inverter banks of storage. Tie them together, put an inverter on it, and then you have plenty of AC power without having to run the generator. Some of these boats actually have separate outlets marked as off of the inverter. It actually works quite well.

Rinker is the perfect boat for that. You could repurpose one of the “it’s shore choice” on the panel for the inverter/house battery bank. Very little reworking and fully integrated.
I had to do some reading to understand the pros and cons. IMHO the cons outweigh the pros. From what i read equivalent 6V vs 12 V setups will have the 6V setups weighing more and costing more. The kicker for me was that if one battery goes out you are dead in the water. if one of my 12v batteries goes out i can still work off of the other one. Costs more, weighs more for minimal increase in AH.
@davidbrooks not true if you lose one battery you are dead in the water. You move either the positive or negative cable to the 2 batteries that are connected in series and still working

How do you figure out which battery is dead? Wouldn’t you need to load test to know for sure?
Can't you do the terminals by the battery switch with 12v and open the hatch? The motor works right, just no power to it? Guess I'm missing something...
@Grahamu yes that works when you have 4. But if you only have 2 6 v batteries and not 4 for two fully redundant banks then you only have 6 volts. I think you have a very workable solution. It is just more expensive and heavier. However from what i read is more durable. This has just been an interesting post to follow for me because it was a new spin on a old topic.
Susan had four 6v batteries on the house side and two 6v batteries on the starting side of her boat. She ended up having 4 dead 6v batteries on the house side. If I had a bigger boat, like a 342 up to a 420, I would go the 6v battery route. With a 280EC, I will stick with my two 12V deep cycle batteries on the house and one starting battery.
