I started my build at end of November as I wanted to upgrade from Meepo but Evolve’s disconnection issues and their battery sag just wasn’t appealing. I did wane evolves trucks though, So I decided to do a clone build with some changes. Did my first test ride today and it was awesome! Here are some photos to start!
Spot welded packs. I used 3 strips of 0.15mmx 7mm for parallel connections. For series connections I used 10Awg wire, which was a overkill but that’s all i had. This was incredibly hard to do. I don’t think I would ever use solder in a pack again. Definitely spot welding the whole thing next time. Shrink wrapping it all. Ready to test ride!More updated photos
Have to say this took incredible amounts of commitment, work and research. I don’t think i have taken a more ambitious project as of yet.
Now for the performance, this is running in FOC mode on Ackmaniac’s firmware and the torque on this thing is just INSANE! Coming from a Meepo I had no idea DIY boards are so savage. This thing just pulls and pulls. The first time I rode it I thought to myself “I have created a monster that wants to kill me”. I can imagine what the torque on this thing would be when I increase VESC settings to max. Getting hella more protective stuff soon.
Top Speed 30 Mph Range 32-34 Miles Pully Configuration 15/36
VESC settings Max motor 40A Min Motor -25A Max Bat 25A MinBatt -12A
And finally I can say that the reason I built this board was because I need bigger wheels and more thane. This board delivers on both as I can ride sort of comfortably in Oakland where the roads are just utter shit. I am also adding my complete parts list in case anyone want’s to replicate.

As you can see board is cheaper and better in performance than evolve’s carbon GT. So maybe this was a really good decision after all.
This is still a work in progress. So planning to update this thread as I finish.
