Doesn’t look good, some packs have a thin aluminum plate, I hope that’s not the exposed lipo cell… the impact probably hurt the internal structure badly, I bet the internal resistance of that cell is slightly different from the others now

throw it in a ziplock then see if it has a "sweet" odour. If it does, that means it's leaking electrolyte. You can save the pack by de soldering a cell

If you have to ask no.

I know a guy with a pack that looked perfect after some training. Rental car started on fire. Luckily it was only the back seat ruined and they got the batteries and other stuff out before it got out of control.
