If you mean are the motors actually hot, then yes. Is there a chance the temp sensor would somehow not be calibrated correctly? Is there a chance that doing the motor detection at around 25c is causing an intolerance in the resistance and causing them to overheat? Should I try a motor detection while they are warmed up at all?

Hmm. Thats less than ideal dude, i think you need bigger motors.
Regarding the detections and inductance and all that other fancy shit, thats way over my head

The real question is “do I want to sand it down?”
Cosmetically, it’ll cause a bump in your griptape. You can sand it but if your wires weren’t tucked in far enough, you risk sanding the cable’s insulation. Proceed with caution imo

Okay, it mostly pretty flat and even, except the excess epoxy on the sides, so I will see what I can do
Different resistors used as temp sensors do have different “base” resistance at room temp (in marlin config for 3d printers need to tell it which thermistor is being used 10k 100k and like 20 options for different resistance to temp tables for different sensors I think). Unfortunately don’t know if you can somehow adjust what the vesc does with regard to the resistance to temp conversion.
What epoxy did you use?
I’m planning to do something similar but with tinned braided copper cable

terminologiy question.
what’s nominally mean here? my understanding is just meant “in name”. or “as it’s labeled” or “as it’s called”. so… I thought it had very little technical distinction and couldn’t be closer to any particular number.

So I sanded it down and the bumps are smoother and not as obvious so should I be fine with the griptape?
It depends on your cutoff settings. LiPo cells get angry if you discharge them below about ~3v/cell, whereas a lot of li-ion cells are rated to be discharged al the way down to 2.5v/cell. That lower discharge cutoff voltage lowers the average or nominal voltage.
Similarly the “HV” lipos and li-ions that have a 4.25, 4.3 or 4.35v maximum voltage end up with a higher nominal voltage like 3.65, 3.75 or 3.8v/cell.
The nominal voltage is basically the average voltage across your discharge. So if you only go from 4v to 3v, then your nominal is more like 3.5, or if you go from 4.2 to 3.5, your nominal would be something like 3.8 or 3.9.
I don’t think this is right.
motor current depends on load. ie the motor will draw more current if it can’t hit the RPM targeted by the input voltage ( batt voltage x duty cycle ) until it hits that RPM or maxes out the battery current available.

I was just trying to replicate a graph I saw before, I think it assumes that it is accelerating at max current and has the perfect load throughout that acceleration.
hmm. I think max acceleration would be battery amps flat across the whole graph. it’s not a function of duty cycle.
If you pulled maximum battery amps at 0.1 rpm though, due to the lack of BEMF from the motor you’d have to step the motor voltage WAY down (and the current WAY up to match), which would far exceed the motor current limit.
Basically at low speed you’re limited by motor current, and at high speed you’re limited by battery current.

that’s right. thanks.
what about the curve at the end of the graph in the motor current line? shouldn’t that be linear?
Bump to my question from earlier: what’s the spacer size on 6x2 wheels? The one between the 2 bearings
