Well, in theory, if you just stayed at the higher voltage all the time and just limited the throttle in one mode, it should perform almost exactly the same as running at a lower voltage. In fact, if you limited the throttle on a 72v pack so that the top speed was the same as a 36v pack, you would have even more torque available since the current limiter is measuring the battery current.

So there is no need for a 2 mode switch then, since the throttle constitute a dimmer switch.
Like I said before, AMPS = Torque
Voltage = Speed POTENTIAL
"Each cell has to carry the same load either way."
This is where we differ.
The equalizer in your " Specific " situation is that your motor runs better at higher voltage.... 5 amps at 80v.. or 10 amps at 40v... equals things out.. so the amp load on each cell is the same..
You either have a magic motor or a magic controller.
Now tell me about your magic motor and magic controller.
There is a tiny advantage to running a lower voltage if you're going slow. The greater the difference between the pack voltage and what the motor's getting, the more losses there are in the inductor (controller).
I don't think the difference is very big, and usually not worth the bother of a dual voltage switch.
