Using round numbers, two 12 volt 100 amp batteries in parallel gives 200 amps capability at 12 volts. Two 12 volt 100 amp batteries in series gives 100 amps at 24 volts.

I understand the result of series and parallel.
What I don’t quite understand is two 6volt in series is 12 volts and amps only what one 6 volt offers.
Is there any advantage adding a 12volt battery with 80 amp at 20 hr in parallel to the two 6volt in series that equal 225 amps at 20 hrs?
