I think I may have fried my Pint…

I received an OG pint from a friend that would turn on. I took it apart, found a tutorial on YouTube on how to trickle charge the battery to get the charger to recognize it. It ended up working and I rode it around for a few weeks. I started to get overcharging notifications on the light bar and if I started uphill I could get the battery down to around 98% and then the error code would disappear. Well yesterday, I was riding it the code popped up and I got a pretty heavy pushback so I jumped off and the wheel was still running, so I picked it up from the front like a dummy and was holding the sensors. The wheel was running super fast and I couldn’t set it down because it was like holding a giant gyroscope. I reached over Turned it off from the button and now it won’t turn back on. Did I fry my controller from letting the wheel spin while it was off? The wheel has resistance, even though the board won’t turn on.
