voltage verses current
Interesting thought. I think just regulating voltage from a series string of batteries might help keep the car runnng at a constant speed for a longer time. What if you have 120 volts to start and the motor only needs 96v. If you can use a regulator to hold the output at 96 you can discharge 24 volts before the car slows down. Changeing from series to parralled or vice versa will not change available watts but you can choose either higher current or higher voltage.
