Humm ok I think I understand. He's including the energy needed to accelerate from 0-50 every 500m BUT he's assuming that it gets to 50 so quickly that for most of the distance it's doing close to 50?

That's my understanding; and, correspondingly, coming to a sudden stop at the end of each 500m.
The main issue in the post is that the calculated range seemed to go down when the battery size was increased. Using the same data and equations, I was not able to reproduce that, but I don't seem to be able to get Bianca to post the details of the second calculation.

CWatters

His equation shows both power consumption and battery capacity are proportional to mass so not possible for range to go down.

Only way for it to go down would be if power consumption was proportional to mass squared or something like that.
