Should i use this lipo ?

Hello , i crashed my quadcopter badly and my lipo got a dent .. when i checked the voltage it was 8.0v (its a 3S lipo :/ )

4 hours later , like you see in the video the voltage is much higher 11v and constantly changing ... I don't know whats happening . I'm keeping the lipo on my balcony in case it catches fire .

Im afraid to recharge it .. What should i do ? should i give it a try or no ?
Here is the video :

Discharge and trash it. There's likely internal damage which could lead to a problem you won't like.

If it REALLY was 8.0v after the charge you either SERIOUSLY over discharged it, which may have caused your crash, or the damage did something to short a cell out.
Shorted cell > very bad.

I think my voltage meter was wrong or something because my battery voltage has been at a constant 11.74 v for 2 days since the crash ..

Here are some photos ( i cut the yellow cover myself to see the damage )
There is a dent but no holes in it .. i dont know should i try to fly with this ? the shipping costs 3x more than the battery in my country ...

If it had a hole it wouldn't hold voltage at all.

That's pretty dented. Dented = damage. Damage increases the possibility of a serious problem happening.
Will it? Maybe not.
But if it does what's your plane, house, and/or car worth? More than shipping? Your choice.
