I know FSESCs don’t have a great reputation but this is getting out of hand. I have now fried my 4th FSESC from normal benchtop testing. No motor connected. Literally just configuring some of the application settings for my DIY one wheel. Luckily I buy them with Amazon so I send it back and they send me a new one a few days later but it’s getting quite annoying.
I know I should buy a brandname VESC but I’m too cheap for that. Is there any reason this could be happening? It usually occurs 5-10 minutes into normal testing. I have the Flipsky anti-spark switch in line as well as a 30A fuse. This has happened to 2 4.20 FSESCs and 2 6.7 FSESCs.
I’ve turned off the phase filter in settings which I’ve heard is problematic. I am also updating my firmware when I first get it. Should I keep it at the stock firmware?
Shall do. My battery is 13S so nominal voltage of 48V but around 54V when charged. The old FSESCs I was using were rated up to 60V. Since they’re crappy ESCs it was probably lower so it’s likely a small voltage spike was frying it. Hopefully the 75V rated ESCs will work.
I must be the outliar because I currently use 5 different FSESC’s and they all worked great. The website states 8V-60V but they also state very loudly that it is a 12S max. I run 10s and 12s batteries and have thousands of miles on each board from daily commute each year.
If you buy a 75100 I would open it and pot the capacitors. I rode mine about 300 miles before the capacitor leads broke from vibrations and started getting really sketch. Ive since repaired with new caps but i epoxy potted right after.
