Cheap scooters charging in dorms..

Like a few others here I store several ebike packs and tool packs in large ammo cans (mortar ammo cans). I lined the interior with a fire blanket and drilled holes to vent the pressure.

I wanted something for convenient charging, travel and use while in a hotel. The bags for $40 on Amazon gave me little confidence. I couldn't find any real testing. In 2025 I found Vlitex, they started selling in the US. Vlitex is a German company, in the business of manufacturing textiles for fire protection. They've been in business for more than 25 years, serving business, industry and government.

They make several size ebike battery bags. Price range is $106.00 to $136.00 depending on size. All made the same way.

This is a 740 Wh battery pack at 95% charged.

The one I purchased is very heavy and made extremely well.

I believe lithium ion batteries bring their own oxidizers to a fire. Is smothering all that helpful?

Containment is the aim of the product. When a battery catches fire, everything around it will ignite.

Those bags tend to be useless, they are up against ferocious energy

Looks interesting. Certainly better than nothing. Too bad they don't make a size for rear rack batteries.

Containment can be an advantage if used with a way to move the container away from combustibles.

Right now, I'm using ammo cans on a cart that can be pulled or pushed out a door.

They are bulky though, and I like the idea of a lightweight bag as a replacement.

Ammo cans lined with high-temp ceramic panels work for me.
Users should be sure to remove the rubber gasket!
