Going from 2/12v to 2/6V battiers - will cables work?

I'm upgrading from 2/12v to 2/6V battiers will the same cables work.

I know I need a larger box for the 6Vs.

As long as the cables are a decent gauge for your loads, you should be fine. Do remember that you will be going from parallel to series connection (you will end up with a spare cable). I used a red cable for the pos->neg connection between the batteries and gave it a spiral wrap of black tape; it helps to remind that it's not really a pos or neg cable in the 12v sense.

Not really sure that it is an upgrade or not.

You can also buy batteries in 2 volts. Just connect 6 together to make 12 volts.

Is this an upgrade over 2 each x 6 volt wired in series ?

I think of it as a way to have less mass per battery package vs upgrade.

You can use the same jumpers. Some will put both of the jumpers in place between the 2 6V batts. If they are red & black it's a visual reminder they connect neg & pos terminals.
If you ever want or need to switch back to 12V for any reason you have enough cables to do it that way.
6V GCs are the way to go for house use.
It's not whether they are 2, 6, or 12V it's that GC batts are made different and serve much better for house use.
Read thru this link for a very good summary of deep cycle batty
Also lots of other great electrical info from a knowledgable source.
