I'm running the motor in FOC so it doesn't have a huge starting torque, rather it's pretty weak feeling compared to a square wave. However once it gets moving it takes off like a rocket. I would like to find a higher torque setting to help with take off starts. I wanted to build this scooter to be as light as possible with nothing added to the steering post. The most cells I could fit worked out to be 20s4p and with 10 amp cells I'm not even using half of what the controller can output. So my options are to either build a new pack with higher output cells or add another pack in parallel and mount it to the steering post. Guess another option could be to extend the base and figure out how to fit more cells in there. However 40 mph on a stick with wheels already feels like possible death if something bad happens, so maybe I should just leave it alone and call this one DONE!
