Is it possible to drill a small hole to get rid of a puffed battery? Can you drill a hole, relieve the air pressure, and then seal the hole?

Not on a Lipo. That's a fire in the making!!!!!

The case is swelled because the lipo cells inside are swelled, drilling a hole in the case would do nothing which is what I think your asking.

Yes, thank you for the answer. I will not be trying that then, thanks again.

Please dont try that...bad idea...❌❌❌😵

Not a good idea!

Oh man, I got to try that at my local indoor track, I am sure to impress!

It could be a 10.000 dollar winner at funny home video's, please make a movie of it!

Better soak your bad LiPo batterie in a bucket of salt water. It helps stop the electrolytes chemical reaction. Then dispose of it in a proper manner (dangerous waste).
