trading out 6 v for 12v
I know this has been beat to death here but before I fry something I would like some help. After looking at RoyB's diagrams I see that when going from 12v to 6v batteries that the 6v batteries should ...

When using six volt pairs there are just two things you need to know, JUST 2
The first is this: The jumper wire that connects the two needs to be the LARGEST wire connected to them. Generally the same size as the NEgative wire unless there are more than one on that terminal then combine them and make it that size.
4GA is common, simply because it is easy to get ready made 4GA jumpers, Every auto parts place has them, commmon starter cable.
Next: There are no six volt batteries in RVs.. Only 12 volt.. (Yes I know I have a pair of Deka G-20's six volt 230 amp hour)
Here is why I say that.
Once you hook up that jumper... Those two six volt batteries, Magically (Well there is not any magic involved) become one BIG 12 volt battery, treat the pair exactly as you would an 4-D 12 volt battery,, BOTH are 12 volts at 230 amp hours.
ALL questions regarding the care and feeding and more are easily answered by thinking of the PAIR as a single 12 volt battery.
How do I charge (Feed) them (Same as a 12 volt size 4D)
and here are some other questions I've seen:
Can one be old and one new
Can one be big and one be small (See footnote)
Can one be Flooded and one AGM
Can one be Excide and one Deka (Different brands)
All those can be answered by asking "Would you want a 12 volt battery that was half and half?)

There was a thread on one of the forums about someone who DID want to mix a small and a large six volt.. This is the one time where you can not mix batteries of different size.
You can mix a pair of Deka G-2 (210 amp hours) with a pair of G-20 (230)
You can also mix a pair of Six volt (See above and pick one) with a group 27 (100 amp hour give or take) or even a 24 (75 amp hour)
But only if you think of the six volt pair as a single 12 volt
Batteries in parallel Add amp hours (Like the G-27, 24 and 4D (Pair of sixes))
Batteires in series MUST be identical and you add voltage
