I crashed on battery and now the battery shape is weird

Checked the voltage is normal

Will it effect the battery?

ouch!
it's a tough call.
I've seen people carry on using batteries that are deformed form crashes. It might not be an issue, but it might affect the performance of the battery a bit. If the inside is damaged it can also cause shorts and fire... I personally would just dispose it for safety, but it's your call. (or just remove the damaged cell and keep the good cells)

I have a few badly deform lipos. So far, they have been fine. Knock on wood. Like Oscar said, it is your call. If you keep using it, I would be extremely careful when charging. Maybe charge it a few times outside.

Here is a tip. If you have lipo with thin shrink wrap, I usually put an additional thick shrink wrap over. This has virtually eliminated my lipo from puffing and deformed from crashes.
