Converted to Lithium-Ion be careful.

There is no evidence that lithium batteries caused or were a part of that fire. What a bad headline. The actual bulletin referenced did, however, focus on a major issue, lack of exit routes. Incredibly sad story, can you imagine being blocked in below deck on a boat during a fire?

It very well may have been battery related, but no one knows. If so, seems much more likely to be a house battery and wiring issue than a customers plugged in device.
