@shaman What is the max voltage for the on/off switch? Can I switch it directly off my 20s battery positive/ground?

All you do is hook up a switch that either bridges the connector pins to each other or opens. Closed is off and open is on. It’s not in any way dependent on the battery voltage

For fitting a “stock” FOCer into one of these boxes with a 20S1P module, the heat sink needs a 12mm chamfer.

I guess the battery module in the front should be flipped so the clearance corner is on the same side of the board
uh I could also do a funky split battery in the front if I wanted.

So you’re planning on 3d printing these boxes? I think you kinda still need some heat outlet, mounting the FOCer’s heatsink to plastic is not good?
I’m also planning on 3d printing a box sometime for an XR build (first FOCer attempt will be in my Pint though). And likely a funky battery split, as doing this in a clean P split you need two BMSes…
Have you considered starting a thread for your build?

I am the only person I know of that has designed a OW box around being CNC cut from a block, but I was planning on using plastic.
here I flipped it. In the previous picture the space under the ESC’s heatsink could have had some kind of thermal coupling to outside the case. Now the lid would need to be at least partially metal.
What do you mean this is my build thread. 
JK I can make one for my progress but I am trying to figure everything out that relates to the FOCer and the ideal configuration for upgrading a Funking wheel, or at least what to try first.
Right now I am trying to figure out if @shaman planned for this thing to fit in so perfectly or it was just magic.

I’m looking to max out a QS 205 50h v3 hub motor around 100-150A battery current and 20s, should I wait for the bigger FOCer’s?

well I guess so if you want to max it out.

But the Big FOCer is posed to be in this league. I just ran a prototype of it on my ebike with a MXUS V3. It’s similar to that QS 205. Went up to 250A motor phase. Though I was gunna tear the frame apart with all that torque…
No more details on that until its further in development though

Ahhh that sounds mental!
I might just give the Smol FOCer a go and maybe upgrade down the road

Yeah the little one does very well for its class. I’ve run it extensively on my ebike. Still has enough speed and torque to keep up with traffic on 45mph roads with a 16S battery. Would be faster with 20S but I’m too scared to go faster on a bike frame.

I’ve done motor amps of 140ish. Seems ok so far but I can lower it if the shaman says so

Me and @Zippy are having it sent from the US to Europe this week. Hopefully we’ll be able to give feedback sooner than later

Just made a little test setup with a 15s onewheel pint pack and a Funwheel hub, works great on the bench!
