Power = speed/acceleration
Range = energy stored
Does not matter how you arrange the cells. If a battery can do 1Kw(power) and store 1Kw/hr(energy) does not matter how you arrange them.
Only thing volts gets you is smaller connectors and better use of DC fast charge systems, but a boost converter from vicor get you 4:1 voltage conversion have over 1kw per 1inch^2 density, so you could go easy 400v to 100v for charging.
If you have winding control over the motor, the total current in the tooth is the same if you have one set of wires with 100amps on it or 100wires with 1 amp on it, the trq will be the same. The total amount of copper the electrons are pushing though is the same.
