Battery drain and speed

Hello I have a bafang bb02 which I must say is great. However I'm trying to solve the following issue.

  • In the morning on the way to work, with a full battery, the top speed is 24mph
  • I use about 1/4 of the battery (max) to get to work, where I park and turn off the battery
  • On the way back, the top is 22
  • I end up with 1/2-3/4 of the battery remaining for the round trip.
  • The route is perfectly flat so no terrain assistance
  • I keep the same gear the whole time and use the throttle
It feels like as the battery decharges it does not put out the same power?

Any thoughts on programming or settings to maintain the max speed? I'm not worried about draining the battery since the round trip is short enough.

Thanks!
 
The rate of electric flow decreases as the battery’s charge decreases.
 
That's what I figured, but is there a setting to keep it maximized at the expense of battery life?

In other words, I'd be happy holding top speed for a shorter time frame than it decreasing.
