those are huge... definitely not meant for a normal bike... more like for motorbikes xD

I think, the chances a controller breaks are high, this is why I hesitate to buy a really expensive one like ASI or Phaserunner or something like that... I had plenty KT controllers, they are fine, but they have no FOC, and only up to 13S. Also the 6 fets one is only good to 1000w or something...

I am surprised nobody mentioned VESC, now that they have native support for Pas, for me it is the way to go. Check Flipsky 75100

I bought them in a Taobao agent... lets see... Does anyone know the big SMD capacitor value right on top? I have also fried it.

But the UART has a 5V line as well right? Thanks for your support. Do you know where to buy a good PAS that works? I am having some problems finding one actually. It is not clear to me by reading the PR in GitHub if 3 pin PAS will work on 5.3. I guess it is better to just find one quadratic one.

has anyone tried this with a normal 5V PAS ? how are you suppose to connect it to the controller? Also, I am wondering, what screen options exist? How do you adjust the power, and turn it on etc? sorry if it sounds a bit noob, but these VESC controllers always confused me... I am still however...

Thanks guys, I decided to queue up for a Nucular 6F controller, and a Puma/Mac 8T. I will try to fix the q128c in the future and use it in another setup, thanks a lot for the suggestions. It actually surprised me this thing with the q128c, I have two q100h pulling 1000w and they keep up strong...

I have made the layout smaller, and put both negatives to one side and holes for 8awg. Size: 51.8 x 23.2 mm, smaller than this with 6 fets... and heatsink.... gets complicated. In between the mosfet, there is enough gap to put a screw, since I am planning with a small plate to press the...

thanks man, will try to squeeze an 8awg, and make those holes with pads slightly bigger. The current to the gates and Zener is minimal right? I mean, less than 1mA probably right?

6mm2 = 10awg. I think it should be fine right? Length is not going to be much (it is for a rc boat). Would you use thicker cable?

drains an sources traces (60mil now), I was thinking to reinforce them with 10-12awg cable afterwards. Rest (15mil) I think are ok right? what do you think?

I am designing a PCB for 6 mosfet version, from 3b version from fetcher. Here comes the board: What do you think? In between the mosfet, I left the perfect space for this heatsink (40x25mm version): https://www.aliexpress.com/item/4001107677711.html?spm=a2g0s.9042311.0.0.5d4d4c4d1fNezv The...

guys, what is the preferred dashboard interface for this controller? eggrider, apt, or ca v3? Thank you!

My q128c (9rpm/v) mounted in a folding bike with 20 inches wheel is trashed. It just stopped running and it is making strange mechanical noises even unplugged. I was powering it with a KT controller that I adapted for 52V/20A (14S battery). It did not last long, maybe 1000-2000km.... So I am...

I am looking for a downtube battery case to host my new 13s3p pack (with Samsung 40T 21700 cells). So far, Nick from Reention told me of a new model 4C-21700, but I can't find it anywhere. Also I know there is another one from Hailong, but to be honest they look a bit too plastic and shit, am I...
