You can get better range by NOT using regen or brakes so much.
EDIT: Since some people decided to disagree since they may not understand physics, let me rephrase and expand my above original comment
Brakes < Regen < Coasting
From a strictly technical standpoint, if you coast to a stop, this is the most efficient. Also, coasting down a hill and burning off the gained speed(from gravity) going back up the next incline, this is also the most efficient. From an energy efficiency standpoint using regen is ALWAYS worse than just coasting, and using brakes is ALWAYS the worst option.
Regen is a great thing for the final few feet(could be a hundred-ish) when coming to a stop. It is also great for sudden slowdowns due to traffic conditions. Maximizing your coasting is best.
