Hi marcoluz, your “max current ramp step” value is 40000. I think it should be 0.04. Could be that you have this…

Good eye @catweazle I can’t see how his Vesc isn’t dead already.

is this the reason why? Cables too thin?

:scream: that solder job looks really bad - you are lucky the batteries are still alive.

how did you get the idea that using like 16AWG cable on the battery is a good idea? I mean you are using 10AWG on the connector so why not everywhere?

The setting should be changed to 0.04. Set it to 0.004 and write config…then it should be at 0.04 if you have this bug in your firmware(what version do you have?). You can double-check it when you read the configuration, after you saved. You could give it a try then…after looking at your batteries I think there could be more problems.

Here is a post of someone who had this Problem, too. His value was 50000:
