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.

Hi Michael,
For 11 years I've been in the Li battery business. We formerly designed
and installed over a hundred Li battery based systems, mostly mobile
installations but UPS and off-grid as well. Since 2018, we no longer do
installations. Currently we sell our own Li-ion brand with many
thousands sold and in use. We have not had any fire or explosion
claims.
Most Li batteries sold in the US are not UL1973 or ETL certified. Many
batteries are very cheaply made to have the lowest price. Based on my
experience I consider any battery not certified as potentially
dangerous. I don't know if Discover is certified and make no statement
about them.
An important question is what will an insurance company do if there is
a claim and the product you install is not certified to these high
safety standards? Worth considering.

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 and it smoldered for a day. 199
degrees fahrenheit after 18 hours. Discover is taking this seriously
and their response has been great. They are in contact with the cell
manufacturer to find a "best practices" for the clean up of the room.
They also have said that this is a first for them (lucky me).
I'm just curious how rare or common LiFePO 4 explosions are? I've never
heard of one in the context of residential storage. This has me pretty
freaked out.
