What worries me about that is that the blanket will hinder my ability to haul the bike the hell out the door as fast as possible. For a bike like this, with the battery permanently enclosed under the floor inside the box (it would take a good 10-15 minutes to take the floor off) I don't see a fire blanket having any positive impact wrapped around the whole bike or somesuch.
I actually do the same as removing my battery is a little tedious and cycling connectors does have a downside.
Good videos.. And you can see the amount of venting on the Bat Safe box so there is a real concern. But it doesn't address that you may be adding to the fire hazard by trapping heat to begin with and actually contributing to causing a runaway event . Additionally that looked like a total of less than 16 cells..not your typical ebike battery that has a lot more potential. I think an ammo can is safe storage, not sure I'd use it to charge.
I suggest that you read it again as it was not limited passenger aircraft.
This is pretty much where my mind goes regarding how much to fear battery fires. Of course it's just something I read on the internet, so I'll take it with a grain of salt, but really, 49 battery fires or even 4900 battery fires out of how many ebikes in the world? Not to mention smart phones and drones and myriad other battery-using-devices??? People post the horror stories, but the internet would bog down and die if the same percentage of people who don't have battery fires posted their "nothing happened today" stories. No kidding, the internet would go down in flames!
I think you'd be better with individual ammo cans for storage.

What does that mean? "Two battery makers having catastrophic failures"? Who were these battery makers? Were they top-tier battery makers? What was your experience with them?

That's my point about spending a lot of money on trying to contain battery fires. Statistically, what fire?
I'm sure I don't understand all that, but it says in 2019 there were 119 ebike fires among about 250,000,000 ebikes in China. Thats one fire for every two million one hundred thousand ebikes. Of course nobody wants to be that one, but the odds are extremely good you won't be. And I don't know, but how good do you think the batteries are in all 250 million of those bikes? Now I'm being silly, but out of all of those bikes it seems possible at least one of the fires could have been due to a lightning strike.
