Alex,
You are correct, he will end up with 12v at the same number of amp hours but if measured as Watt hours it will end up being 12x420.
The number of amp hours supplied by each "cell" does not change, only the voltage if sequential. If parallel then he will have 2v @ 6x420 amp hours.

His view is that he will have 6 x 2 volts to make up 12 volts and 6 x 420 amp hours or 2520 amp hours
with the 12 volts system.
My thoughts is that the amp hours will be 420 amp hours at 12 volts.
He is a lawyer so please cite your qualifications and reference something that sets out the science.
Thank you.
