Is this Pack still good?

It now has a close friendship with rocks :/

I wouldn't risk it. The two times a battery is under the most stress is during charging and discharging. Thats either going to fail indoors or in the air. And Murphys law doesn't wait till you're ready.

That does look like it pierced the cells.

Electrolyte smells sweet. If your pack does too then its time to retire it.

Give it a sniff if it's sweet you need to either remove the bad cell or put a nail through the hole pack 🔥😢😂
