    Super Capacitors for "Burst Mode"?

    Thanks guys, you are right. I never calculated it with the size and weight of the caps. And indeed, the promised farads are from 100v to 1v orso And not in a range between 100v to 90v for example. So there goes one of my fantasy balloons :mrgreen:

    Super Capacitors for "Burst Mode"?

    What about supercapacitors for just a 5 sec burst. I was just brainstorming about building a really fast E motor scooter. A big QS motor that can handle 30kw peak in the rear and one in the front. 2 big controllers, a simple 4kwh 100v 18650 pack for cruising around town at max 8kw of power...

    Build my own winch for watersport. Broke my controller?

    I ran 80a battery current with an 18 fet at 18s lipo The 24 fet can run 150a If you ask them. They can program it. A 36 fet greentime is even stronger. That would be overkill. Those controllers can run with hall sensors and also sensorless

    The gasoline jetboard makes almost the same sound as the electric version in your video's :mrgreen: I can imagine that trouble after trouble is demotivating you. I also stopped for the same reason with my electric jetboard, but now my electric hydrofoil is almost finished. It has so many...

    Electric Hydrofoil/E-Foil

    Yes ! Congratulations . The foil etc looks great, you just miss some surfing experience. I kitesurf for about 20 years, but foiling took me a few days to learn it. Keep trying and keep the board flat directly when it will come up, lean forward. And try standing with knees bending. But first...

    Electric Hydrofoil/E-Foil

    About the trolling motor. If you replace the prop with a higher pitch prop you increase the watt also. So maybe you can reach 2000watt. You only need this higher power for just a few seconds?

    Electric Hydrofoil/E-Foil

    In the past i have used a turnigy c80100 rewind to 45kv and had sync issues. Also used a revolt 10 motor i believe 45kv with ceramic bearings and epoxied stator. Also sync issues with different controllers. A direct drive under water was not so easy. Torqeedo proofed itself and uses a gearbox...

    Electric Surf Board

    I also spend a whole lot of money to build an electric outboard that can get a boat in plane. Than i spend a lot for the electric surfboard. The final stage would have been a wider board with flat bottom, almost no rocker line. They dont exist i think so you need to have it custom build. Or...

    Electric Surf Board

    Hi, I think it is a bit too small, you do need about 11kw to get a board on plane. Maybe a wider board and light person it is ok. Kv and voltage is ok. But i think you need watercooling also

    Electric Surf Board

    325 euro for the jet free shipping. The motor was running fine letting go of throttle and controller died. At least, some kind of timing error. And i also think why, battery wires were pretty long and motor/esc wires were very short. I found this...
