Morp and I discussed this in another thread, I copied this from there.
So by that formula we are not that different.
The longer, not too many stops, some pedalling:
8.78AH / 22.5M = 0.390 AH/M x 40V = 15.6 WH/M (40volts being that actual voltage of the 36v cells)
The work run with lots of stops and minimal pedaling:
1.88AH / 4M = 0.47 AH/M X 40V = 18.8 WH/M
So I'm running 0.4-0.5 ah per mile at 36v pack. I have an amped rear kit which only draws 15 amps max at 20 mph
