14 mile drive

It was the longest any vehicle ever went on a single battery. Set it to 6mph. Had the headlights off. Speed was somewhat variable because of the low accuracy of the inverter. Not sure driving the ESC using I2C would make the speed more accurate, since the bottom line is the number of bits in the 8khz waveform.

This achievement took 4Ah or 90% of the remaning capacity in the last full discharge. It would have a hard time going any farther or any faster. A fresh 5Ah battery would probably go 17 miles.

Did you have to carry it back 14 miles?
Or, was it 7.x there and back?

It looks like you have clearly confirmed that moving to brushless is far more efficient.
If we could get the electric car conversion folk to develop cheaper conversions, we might make a dent in the dependency on fossil fuels.

'Current' amateur conversion of passengers cars is still dependant on brushed DC motors, essentially not much different than Edison technology.
