Sorry for the delay. I promise to get back to this. Here is what I learned this far. I suck at programming really fancy ESCs. The one I have is more complicated than a standard VESC 6. Working with the guys that made it, I was able to get rolling but not optimally. The 1600w motor went dangerously fast on concrete, but could hardly get rolling on dirt. This could definitely be something that might be fixed with better programming. I haven’t tested the 3600w motor.
Does anybody know of an ESC that might work with this other than MakerX’s imaginary product? I haven’t really checked in a while.
When I get back to 3sk8 design, one of my first projects will be to make a really durable bracket for the axle. There is a lot of torque at the axle. On my street decks the axle wears at the bracket and with time it spins free. I’ve been using basic steel that can be found at any hardware store. It isn’t that durable. I’d like to do a CAD rendering to send off to a machinist, so that I can have it milled from some invincible shit. This is going to be very important for AT success. Most scooter hubs use the same universal axle as ebike hubs. So one bracket would work for many wheels.
This 16s compatible ESC based on VESC recently popped up at ebmakers.com. There is a 200A version and a 100A version. The 100A version might be a perfect match for the 3200w motor and at $195 it isn’t absurdly priced.
Maybe it’s time to get back to this project. The deck will be a breeze. Integrated with interior room for a multitude of cells. The brackets are something that I need some help from people on the forum that have metal working and machining knowledge. I can make the CAD rendering and a prototype form soft materials, but the bracket really needs to be machined from some serious shit. There is a ton of torque happening at the axle and if the material is too soft, the axle will spin free with time.
This one is different. They still have the pre-order 200A VESC6 listed as sold-out on the site. I haven’t seen this one yet. This one is available. The 200A version ships now. The 100A version ships in a week.
The 100A is kind of exciting. If that esc were to work, a person could put together a robust motor/drive-system and ESC for $450 delivered.
I’m going to make a custom battery for the upcoming version of this. The one I used was a bit of a mystery. I don’t think that it had enough nickle strip to carry the amps.
I bet I could make a deck that could hold a few more cells than that. It would be nice to have the batteries in the core of the deck. The giant pelican case felt wonky, but it was also a 16s5p.
