Obviously you can offer for sale whatever you want. But why would you think this capacitor would have any value to an EV system?I'm not really that much into how capacitors work and what the ratings are, so I probably couldn't answer that correctly. I remember the shop that built it said they were very high quality capacitors and they were made by Philips.... I believe they are electrolytic capacitors, if that sounds right.
I know it has three capacitors inside and I was going to open up the box and take some pictures, but the box has a water-tight seal and I didn't want to break the seal.
They charged me almost $200 for it, so I was assuming it's worth at least $60, but if not, you can offer me what you think it's worth -- you probably have a better idea what it's worth than I do.
