Fire and explosion proof bags for batteries?

[AlanW]

As a newcomer to the world of e-bikes, well my wife is should I say, but I was wondering about the perils and pitfalls with the storage and charging of e-bike batteries. Firstly, I would never leave my battery on charge if I wasn't in the house, nor would I charge it in the shed out of sight of the house.
But I've just watched a rather alarming You Tube clip of a lithium e-bike battery catching fire whilst in a supposedly "fire proof" bag, it wasn't pretty to say the least!!!
So, who keeps an e-bike battery in a fire and explosion proof bag, and if so, what make is it

Best thing you can do really is to charge and store your ebike battery in a neighbours garage.......

I wonder how long it will be until house insurers start asking if you have an ebike at the property?

Not an ebike but as a racer of RC cars I have to charge my race packs in lipo bags 👍

I run an extension lead out of my garage to the charger and charge the e bike battery outside well away from any structure.

I don't have an e-bike!

I wouldn't use a 'fireproof' bag in a milion years and I just follow the manufacturers instructions when charging my battery.

Buy reputable brands of bike or at least battery and charger, not aliexpress specials or home made batteries, take reasonable precautions like not leaving it on charge overnight, and stop worrying.

It's not just eBike batteries. There is a risk from any battery as trips through airports with laptops will show.

Managed to lose my Varia today. Fell off while going over some of the many pothole we have around here. It didn't survive 20 minutes in the traffic though I was quick to retrace my route.

Found it and wondered why it was warm so opened it up to see the warning inside. Will put it somewhere safe until I can get it to the local dump which has containers of the stuff - beside the waste oil.

I hadn't heard of fireproof bags, but you can get fireproof boxes that work:

This is a good question ... but I guess we could to countriles like NED & GER to see what their experience is?

With the amount of rechargable batterys one has at home they would have to include that at well
not forgetting the EV out on the drive or in garage

Some years ago there was a lot of dramatic articles in the papers about laptop battery fires.

Then ecig battery fires

now ebikes and e-scooter fire are in vogue so we get articles on them

same batteries - same problems
buy cheap and buy low quality - including the bits that prevent fires!

A fire proof bag… that’s hilarious! Have you ever seen a battery go up?

I spent a bit of my career in materials testing and I can offer the following:

-failures involving chemical fires are the most entertaining and the hardest to control.
-the hardware containing a runaway chemical correction of the size crated by a battery pack costs more than the e-bike is worth.
-destructive testing is a lot of fun.


funfact: you can make a substantial hole in a parking lot with about 500 grams of powdered magnesium and the right oxidizer.
