For future rants: mAh is a measure of charge, not current. And batteries don’t have “power stored” — they have “energy stored”.

When you make a statement like “A 2000mAh hour battery at 2 volts has half the power of a 2000mAh battery at 4 volts,” it’s a bit nonsensical — a battery does have a certain amount of power available, but that amount is not charge * voltage, nor is it even necessarily proportional to the energy stored.
