but presumably it takes more energy to get up to speed.
IE you will pull lots of power accelerating to a higher speed (with more 
aero losses) then decelerate at 0 power, then pull lots of power again 
to maintain a speed.
You would be best off accelerating at the peak efficiency of the motor. 
Then perhaps optimize the motor selection to have an efficient cruse 
speed. Your batteries etc will provide much more energy at lower current 
draw to boot. Especially with lead acids.
