One thing that puzzles me is the worry about the gauge of the wire that connects two 6V batteries in series. The length would be 1 to 1 1/2 feet and the load about 30 amp. Charts tell me that 12 or 10 gauge would be sufficient.
But people are talking about fabrication 1/0 gauge connectors. I may be not understanding something or perhaps my memory of a 30 amp fuse on my positive lead to the battery bank is wrong.
What is wrong with just getting a short 4 or 6 gauge connector from the auto store?
Were you checking a table for 12V?
The wire gauge that's needed is dependent on both the voltage, amps and the wire resistance which is dependent upon length and gauge.
The wire gauge you suggest is OK for some 12V applications.
Example: A 8A AC appliance would with an inverter will draw about 90A from a 12V battery and small wire would quickly melt.
Yes it was a 12V table and if my memory of a 30 amp fuse at my battery is correct then a 12 gauge would be recommended.
Of course higher amps require a lower gauge. The chart indicates that a 90 amp draw requires 8 gauge.
In either case it would seem prudent to go a little lower in gauge for a safety margin.
This is all for 0-4 feet.
