Introducing the FireSak Flame-Retardant Battery Storage Bag – a small, high‑protection bag designed specifically for lithium batteries. Built with four layers of flame-retardant material, this battery storage bag helps contain heat and flames if a lithium‑ion battery overheats or enters thermal runaway, keeping your home, garage, and charging area safer.

Use this FireSak as a fire resistant storage solution for removable e‑bike batteries from Surron, Super 73, Rad Power Bikes, Hey Bike, TurboAnt, Lectric, and more. As well as laptop batteries, drones batteries, or other Li-Po or Li-ion batteries. The FireSak comes in 4 sizes, Compact, Small, Medium, and Large. Regardless of your battery size, we offer a FireSak with enough space to still allow room for ventilation and safe handling.

The FireSak bag includes side pressure‑release vents to help vent gasses more safely in case of an explosion, plus double‑stitched, kevlar-fiber reinforced handles and shoulder straps rated to support up to 70 lbs, so you can quickly move a burning battery outdoors without the bag failing. Whether you’re storing your e‑bike battery overnight or transporting it on a trip, this flame-retardant storage bag adds a critical layer of defense against lithium battery fires.
