Agreed, I am waiting for a response from Enertion to see if the VESCs are covered under any sort of warranty. It is a hard pill to swallow when you spent $240 on speed controllers that lasted you two weeks…
If I could do it over again I would use high strand silicone coated wire, heat sinks, and lower the temperature cutoff range so I could be confident that the VESCs will run nicely for a very long time.
The VESC default temp settings are fine. I have been trying to burn one up with heavy use and have not had any success. I have even gone as far as intentionally overheating it repeatedly and haven’t been able to produce a hardware failure.
