After weeks of riding trough salty weather the first VESC died 
. I used it for at least a year in FOC, no problems at all. As you can see it went trough a lot…

Wow look like a nice challenge 
… And hope there is not so much of corrosion under this salty crust… The last one I have seen with these kind of damage was damage beyond repair (well, it as also pass a few hour submerge in salty water).
Edit: here a picture of it
Wow, I can imagine the challenge :P.
Are you still driving with Encoders?Oh my heart bleeds when I see this kind of stuff 
btw: the big tht diode is new, right ? Is it some kind of reverse polarity protection ?
It is a tvs diode, to protect the curcuit against overvoltage.

After some cleaning:
Note the wear on the FET
.
Some possible issues:
Current sense vias are almost completely gone.
Metal plating on the caps almost completely gone.

Is this a long term solution for upgrading to direct fet 
Just wondering,
……how?! 
I’ve never seen an epoxy case worn in that bad- Or at all, for that matter.
