Manual says to use a diode on pin 26 to battery positive, anyone know what diode to use?

My controller came with a short wiring that had it built in.

How much current can the 12v output on the cl350 put out safely?

The 700-1000 show 5 amps for the 12V but I don't know if the 350 is the same.

I just checked it with a mutltimeter and mine has it too.

Why does he set it up not using the hall sensors?

Not too relevant in that video I guess, haven't even used Halls yet with this controller.
If you have Halls connected it should auto-detect them.

I think he mentioned it was a QS 138 so should have hall sensors, is there a reason to set it up as sensor-less if it has sensors? Will it respond the same either way?

Depends on the motor, I am in the process of adding an encoder to a high voltage motor since it won't run well under load.
I do have a qs138 that I could test just sensorless, it would take a while though to set up though.

I have a QS 138 4kW that I'll be setting up that's why I was asking.

I would be using the halls for sure.
On one motor it took me lots of trial and error just to get the motor to spin.
With halls you are tracking of the rotor position so it'll tolerate incorrect parameters better.
I like sensorless (in theory) because if you lose halls during a drive you can change it to sensorless to get you home.
But you have to get it to work first, otherwise the motor will just be all over the place.

That's what I figured and wondered why they did sensorless on a motor that had sensors, seems weird.

VESC Tool app, (Android), sees my controller, asks for a PIN to connect, shows examples of 0000 or 1234, but I get a timeout error with both. Any ideas?

Yes, try 147258

Thanks, that did it. Where did you find that number?

The app worked well, got it spinning after a few tries and it seems smooth. The PC software not so much, I'm not sure why it behaves differently when controlling it from the PC vs the app, I wonder if there may be a communication issue with the USB cable even though it's the one they sent me with the controller. I first tried setting up the motor with my laptop and had time out and disconnect issues, then when I finally got it the motor was really jerky and didn't sound good. Then I used the app and did it again, as I said it runs smooth on the app and now better with the laptop but not as smooth as the app. This is on the laptop:

Mine had an issue with the USB connection disconnecting intermittently. I determined it was a bad connection on the controller's 3 pin connector for USB. Try enabling TCP bridge from the app and then connect from your PC using tcp (mobile app and pc have to be on the same subnet) instead of USB.

Seems as if that's an important data point they should include in documentation.

Yes, absolutely.
I think there is a lot that should be included in vesc documentation as well. If you find something it is 5years old, and 10 updates ago and not relevant any more.

Yeah it's a bit of an adventure figuring it all out.

I also had to disable the temperature sensor in the setup to get the motor to work, it was reporting over temp
