I am curious as what makes two 6 volt golf cart batteries better than one 12 volt battery?

I may need to replace my 5th wheel 12 volt battery and want to know what the benefit is of the two 6 volt batteries?

Thanks!

Well first in the sizes we use in RV's it is hard to find 12 volt DEEP CYCLE..
A deep cycle battery can be run down to 50% before serious damage starts happening. but the more common MARINE/deep cycle should be kept 75% or 80% full and STARTING batteries 80-90 percent minimum charge.

GC-2 are DEEP CYCLE (6 volt)

Second. they are a very popular battery.. Sold by the pallet load to golf courses all over the USA.. So they are cheaper (Economy of scale) Making them the most "Bang" for your "Buck".

Put 2 of them in series and you basically have a 12 volt 4D (220 amp hours at 12 volts) but it is like 4 times easier to install cause each "Half" of the 12 volt battery weighs only half as much as the 4D.
