According to the ebikes.ca motor simulator lower voltage at higher amps makes more power than higher volts at lower amps at low wheel speed.
Now try getting that same low speed power (for climbing) with a single voltage while maintaining the same moped top speed as the higher voltage at lower amps. This while using a battery pack with the same number of cells (at the same stress per cell). You won't be able to do it. The stress per cell will always be higher and that is why you will always need a bigger battery pack when using a single voltage.
Are you ready to throw in the towel yet and admit I am right about this?
