@vitormhenrique I don’t understand this; wouldn’t there be a spark on connection with or without the capacitor functioning?
A while back @lowGuido taught me that capacitors slowly age and need to eventually be replaced. If someone has a recommendation for their lifespan, or how to test them, that would be helpful!
While this thread is about VESC issues, I often hear from vendors that no one weighs in when their VESC is working well, so I’m gonna share my good experience:
I have a VESC from Enertion, the HW4.7 batch from September 2015. It was manufactured to spec (as far as I am able to tell) and has been working great for 125 miles on my esk8. I soldered the connection wires and cap myself, added a cap to C18 to improve FOC performance, soldered the cable for my GT2B receiver to the board, used an ST-LinkV2 to install a bootloader, and covered it in heat-shrink. I’ve updated the firmware several times with Ubuntu and run in FOC mode with no issues, but there was a learning curve to figure out how to configure it, especially with regard to voltage cutoff and braking. It’s mounted in my enclosure using velcro and is wrapped in foam to minimize vibration.
There are so many things that can go wrong with VESC, my good experience is 80% luck and 20% practice. I would feel disappointed if I received a DOA VESC or near-DOA. Hopefully all that we do as a community can help the vendors to learn and improve.
