Hello electric skateboard builders! I have recently finished my very first esk8 build and have now taken it out for a few runs, however I am running into a couple of problems.
The first problem i’d like to address is the acceleration from a full stop. I have noticed that my (dual) motors (sk3 260kv brushless-outrunners) jutter or stall when i try to slowly accelerate from a complete stop. I am not sure weather this is due to the (kv) of the motors being too high or something to do with my vesc settings. Heres a video
The second problem i have noticed is that whenever i connect the circuit in the board to turn it on, a blinding spark goes off. this is kind of discomforting, and i was wondering what could be causing the problem and if there are any solutions. Here is a video My hypothesis is that the voltage stored at the end of the connector is built up and when the connection is made, such a small surface area is initially touching, the electricity has nowhere else to go but out. using a volt meter i noticed that the energy at the connection is something like 30V and maybe it is because of the large amount of energy? I have no clue, this is my first time doing this…
Here is a picture of my circuit diagram and the actual circuit
On the bright side, i have achieved a top speed somewhere between 35 and 40km/h, and got a time of roughly 61 seconds for a full lap of a 400 meter track.
