Michael, it is super scary to hear these stories and they are a good reminder that Li-ion technology still has risks. I am glad the manufacturer is taking care of you, but it is concerning to see that the battery safety systems allowed the thermal runaway event. Hopefully, the fire department code

The 6650 definitely meets all the UL's, ETLs, and UN's. Probably the first one to do this and since Michael said that it is a first for Discover, the jury is out until an FA is complete. Good points by you Larry, but not valid for many thousands of Discover AES 6650s. Dave Angelini Offgrid S

Never heard of one with LFP. The cobalt and Magnesium Lions are definitely out there. Was this a 6650 model Michael? Going to be fun times doing a failure analysis on this one. Dave Angelini Offgrid Solar "we go where powerlines don't" [1]https://offgridsolar1.com/ [2] [1] e-mail offgridso.

Two days ago, one of my clients came home to find the door of his powershed blown off its hinges and a smoldering Discover AES. The case was still intact and the entire room is coated with a fine graphite-like powder. The fire department was unable/unwilling to do anything to cool the battery down
