    Electric Mountainboard V2

    I thought i wanted to share my latest design improvements for my electric mountainboard.

    Although probably not necessary, I used 100% infill for mount body and 20% for the rest.

    What's new?
    I changed from chain to htd5 belts. This makes the board more silent, slightly more efficient and easier to built. Another thing is that the new pully is 3d-printed and designed to fit the wheels and trucks perfectly making it much easier to center (this was a minor problem with the old board. at high speeds it would create speed wobbles).
    The new design is also a lot prettier in my opinion.

    • 30x 18650 samsung 25r cells
    • 10x 18650 Cell Battery Holder Box from ebay (3 slots)

    Remember to get wires, charger and connectors for the batteries if you don't have any.
    I also recommend an antispark xt90 between the batteries and electronics or as a loop key.
