I built an electric longboard two years ago using the following parts:
2 - 5000mah 11.1v 3 cell lipo in series to make 6s 5000mah battery
90mm wheels 16 tooth motor gear 40 tooth wheel gear
rider weight + board weight - 165
the cruising speed was only about 12 mph, with the top speed being only 13mph. The range was about 5 miles and crapped out then because of the voltage cutoff on the esc, and the bluetooth phone app I was running with an rfduino and a regular arduino running off of a 9 volt battery drained it.
Did i do something wrong? why was the speed so low? was it the high kv rating and a low torque(and large wheels)/low number of cells?
Now I know more and am building a V2. The parts I bought are listed below, they are shipping right now:
4 - 5000mah 3 cell 11.1v lipo high discharge batteries in series to make a 44.4v 5000mah battery.
Same trucks and wheels and gears/belt: 90mm wheels 16 tooth motor gear 40 tooth wheel gear
rider weight + board weight - 175
Assuming i set the vesc up correctly, what should be the top speed and range(assuming I run it around 15-20 mph for its full battery life(assuming the 80% rule as to not damage the lipo’s)).
Thanks in advance!
