DEFINITELY DON'T BUY cheap Li-ion batteries! They have horrible QA/QC and are much more poorly/inconsistently made than the name brands, and many/most/all of them DO NOT HAVE SAFETY features that the name brands have.
the report is here.

Adam Savage talks to the people that made the report

They attributed a battery related fire that occurred on the dive boat that killed many divers at the Channel Islands several years ago.
Thermal runaway is a real threat. It’s amazing how large of a chemical fire footprint a AA Li-ion battery causes when it blows.
