Warning: My backup battery pack almost caught fire on a 737 tail repair

Was working on a 737's HF antenna last Thursday and my spare lithium battery pack swelled up real bad in my tool bag. I had to toss it in a fire bucket out on the ramp before it went up. Has anyone else had issues with those high-capacity packs under the tarmac heat?

Swelled up real bad" sounds like you just left it in the sun too long.

Read a similar story on an aviation tech forum last month actually.
