Amps and amp-hours alone tell you nothing about energy usage.
Do you relize that at 72 volts or 36 volts you can go the same distance with the same watt hours and speed ? Or you can go faster at 72 volts if you wish and
use twice the watt hours with the same amp hours ? LOL Or as you say you can paralel two 36 volt packs and go 40 miles on 6 amp hours at this pace.
