One month ago I built my first electric skateboard. Decided to change my ESC for a VESC. After trying to run it in FOC mode the motor started jittering at startup. So I put it back in BLDC mode. Pulled the trigger. And BAM. Big spark from my DRV8302. See the pictures for the burned spots on my VESC. What went wrong? Is it my fault by setting some wrong parameters? Or is it just a faulty VESC? I assume this is not repairable, so what do I have to do so this does not happen again if I buy a new VESC?
It is a 12s setup with a 230kv.

esk8.de says this on their website:
“WARNING: FOC is still in deveolpment, therefor we recommend using the VESC in BLDC mode only! Using FOC happens on your own responsibility and risk!”
Well it is hard to find proper reviews of the VESC-X since it is not officially released yet. They claim it is 12s compatible, so it should be fine. But what is wrong with a 230kv motor?
Thank you all for answering my questions.
Well I first started out with a complete kit from which included a 12s torqueboards ESC and a 230kv motor. But then I wanted something more programmable. And blindly assumed that a VESC would fit my needs. But lesson learned, I need to do better research next time.
I feel your pain brother. I just learned this five days ago. I stumbled across this forum because I couldn’t get any response from Tb. I didn’t even ask them to pay for it I just wanted to know was it something I did
So, I don’t know if I’m the only one that noticed…but your screenshot of settings shows your battery cutoff start and end at 36V and 33V respectively. Those are good settings, for a 10s setup. But if you’re running 12s it should be 43.2V start cutoff and 42V end cutoff.
I actually have been running the TB VESC and 230KV on my board for over a month. Over 200 problem free miles so far.
You can run 12s in FOC. I have 8 VESC 4.12s in FOC at 12s, hummie runs at 12s in FOC, and same with chaka with chaka vescs.
What you can’t do is run 12s FOC with a standard enertion VESC and not expect problems…
I have also switched between FOC to BDLC and back to FOC before with no issues… It’s where you choose to buy your vesc from that determines what you can do with it…
I hope the vesc-x fixes these issues. I will let you know when I beta test one if you can run 12s in FOC, since that’s pretty much the only way I run…
you can’t even run 10S in FOC with Enerton-VESCs but they are cheap: 1 Enertion Vesc + 1 DRV-Repair is still cheaper than 1 Chaka or 1 esk8.de-Vesc which can blow up too
