Overheated LiPO battery venting twice

A 7.4 Volts LiPO battery was destroyed by overheating it with a coil of resistance wire wrapped around it.
The two cell battery vented twice which can be clearly seen and heard in this video.
This LiPO was electrically abused last week prior, but the leads melted off. ( still took 20 Amps !! ) hence this destructive option was chosen instead of puncturing it.
