Adding two 6v to two 12v?
Hi All, We just moved from a 5th wheel toy hauler to a new class A motorhome. I'm not sure if I should do another set of 12's or add 6's in series. In an ideal world I would swap out all to 6v's bu...

Since the 12s are new, you can get new 6s or new 12s to go with them.
If you choose 6s, the way I bank them is as two big 12s instead of as three 12s. That is, first put the two 12s in parallel then parallel that pair with the two 6s (in series) Now put your load/ charging wires on so that the pos go on one pair and the neg on the other pair.
You can parallel different AH size batteries with no issues at all. What counts is if they are in different conditions as with an old worn battery and a new one.
If you don't find it convenient to bank them all for loading and charging, you can have more battery by using a separate bank for your inverter and another bank to run the rest of the rig.
That way you can have two banks in different conditions and they won't be in parallel. You just need a way to charge each bank, which is not rocket science to arrange.
