Simply put higher voltage equals higher speed, coupled with lower current equals longer range. am i right about that, or does it work a different way??
There's no free lunch, or everything would be run at super-high voltages. If you set a pack up for higher voltage, the amperage goes down. The available watt-hours remain the same, but higher speeds use them up faster, so range goes down more than travel time.
