Electric Mountainboard V2 by Fjederhaek

Last crawled date: 3 years, 1 month ago

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.

Battery: (I think my battery pack is kind of a mess so I'd recommend you design something yourself)
30x 18650 samsung 25r cells

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.
There will be a video at some point, but not before 2019.
