In this case from a longevity of use standpoint, the 6V outshines even two G27s.
Yes, but you STILL need 2 batteries.
Remember AH does not double with two 6volt batteries in series; just the voltage. AH does double with 2 - 12 volt batteries in parallel.
So 2 - 6V batteries above = 12 volts at 474RC minutes (197AH at 25A)
or 2 - 12V batteries above = 12 Volts at 360RC minutes (150 AH at 25A)
Check the difference in weight and cost of the bank as well.
The attachment shows how to convert RC to AH
