Fire-resistant storage bags

Built to store and charge lithium batteries with less mess when things go wrong. Did you know: Lithium batteries in our favorite toys can, and do, explode for various reasons at ANY time? Lithium batteries cause hundreds of house fires in the USA every year.

Intentional Design

We tested our bags in-house. Enough to learn that exhaust ports are necessary when dealing with large battery fires. Large FireSak has two of them. Cheaper bags have none, and explode.

    Really cool idea, not as good as a steel vault or anything, but the material is thick and probably a lot better than nothing!

    I got one for my e-bike battery but then my Inmotion v9 to haha. I like the straps and also if i don’t ride for a while it keeps them clean in the bag.
