That's a pretty bold statement.

There's a much more comprehensive article on this issue now, pretty much confirming that legitimate EAPC are near zero risk:

Stupid people buying cheap batteries and not keeping an eye on them
Agree rhey are stupid but how do you keep an eye on a charging battery? Even if you see the instant that it explodes there is nothing that can be done
My bike whilst stored in the hallway is taken into the living room and charged there where I can keep an eye on it. Once in a while I put my hand on it to see if it's getting warm.

You might not feel any heat and once that thing starts burning you're too late cos pulling out the charger or pouring water on it won't stop the process. You won't get the bike out you'll just have to get out of the house and get everyone else out too and maybe all your neighbors if your property is attached.

It's a straight run from the living room to the front door. Trust me, if it ever started smoking, the bikes out of the house.
We're not insured so to hell with taking that risk.
Having said that.....yesterday I started a complete strip and rebuild of the bike without all the ebike gubbins. I'm trying to go unpowered. I hate the weight of epower.

Mm vantage.
I fear if it starts smoking it may well be too late.
I wouldn't fancy running anywhere with an unstable about to blow lithium battery.
You have seen the vids?
Personally i wouldn't touch a "third party" ebike battery with a bargepole. Three bargepoles lashed together wouldn't be enough.
I'd check out the incidence of fires with these things in London. Several fatal. London a good test bed for these things, lots of people. Lots of users of the things - particularly amongst the young and the delivery community.
London fire brigade has figures and has expressed serious concern. To put it mildly.

You'd think they would mention the brand of battery so people can avoid it, or maybe mention the amps he was charging at. Without knowing any of those details, it's a useless news story.
We'll always be together, together on electric bikes.

Willing to bet the customer doesn't know any of that. If I asked you what battery your mobile phone or laptop (or any other cordless appliance for that matter) had, how many Ah it was, charging rate... Would you know?
Also, there are 1001 random brands that pop up, produce some cheap crap for a while, disappear and reappear as some other brand, repeat...

There's an argument that maybe, if it's a self-build, the customer should have done some research, ensured they matched the charger with the battery but again, if someone is going off what they're reading on AliExpress, it's probably wrong and they probably don't understand half of it anyway.

Which is the point I made about legitimate e-bikes from reputable brands being near zero risk and everything else being the problem.

So the ebike ( which you've said is heavy and maybe already going off like a flare ) is blocking an exit?

It's in the living room with you who has to get it down the hall and out through the front door --- before or after getting everyone else down the hall and out first ?

Is something picking at you?

The only other person in this house is my daughter who works and the dog.
The chances of this battery going wonky are slim at best.
Trust me, I'm no idiot. Every risk has been taken into account and if I thought for one split second that my battery would put my daughter, dog or I at risk, it wouldn't be in the house.
Lets leave it there shall we?

Just trying to make you aware of the danger -- you may not feel any heat before it explodes -- you may only have 10 or 20 sec to clock what's happening and make a decision on a course of action ie do I get everyone out first or take the chance I can move the burning battery / bike ( which has jets of flame and noxious gases spurting all directions ) out the living room down the hall and out through a locked front door first.

Personally if the battery was in the living room by itself I'd have it with a breeze block with some high temp gauntlets or a shovel in the room. If the battery goes up I'd throw the breeze block out through the window ( to smash it ) followed quickly by the battery picked up by me with the gauntlets on or with a shovel. If it's a double glazed window the breeze block can bounce off it so you'd need to be sure it goes through. Or keep a window big enough open.
