Ebike Battery Bag - Waterproof and flame resistant (Size Large)

Introducing our high-performance large ebike battery bag, built for the bigger and longer battery packs that will not fit a standard bag. With its easy-to-use hook and loop straps, it mounts to any bike rack for a secure, hassle-free, tool-free attachment.

This large-size bag is engineered to accommodate oversized and extended-range batteries, including larger packs like the new Juiced Scrambler HT and Scrambler FS batteries, plus many fat-tire and dual-battery ebikes. Not sure which size you need? If your battery fits within 3.5" x 3.5" x 22", our standard (small) battery bag may be the better fit.

Safety and protection are our top priorities, which is why our battery bag is meticulously crafted with a waterproof and flame-resistant inner liner. It has successfully passed the FMVSS 302 Flame Test, providing you with the assurance that your battery is shielded from potential hazards.

The bag features a sealed construction, combined with a convenient roll-up closure and reliable buckles. This design ensures a watertight and secure enclosure, safeguarding your battery during your cycling adventures, traveling or long-term storage.

How to choose the right size battery bag

• Go large for oversized packs. This bag is made for longer, thicker, and extended-range batteries, including many fat-tire and dual-battery ebikes.
• Choose small for standard packs. If your battery fits within 3.5" x 3.5" x 22", the standard (small) bag is the better match.
• When in doubt, measure. Note your battery's length, width, and height and compare to the bag before ordering.

Ebike battery bag FAQ

Is this ebike battery bag fireproof?

It uses a flame-resistant inner liner that passed the FMVSS 302 flame test, so it resists ignition and slows flame spread. No bag makes a lithium battery fully fireproof, but the liner adds a meaningful layer of protection for riding, transport, and storage.

Will my battery fit the large bag?

The large bag is built for oversized and extended-range packs. Check the tested list above, or measure your battery and compare before ordering. Standard-size batteries fit the small bag.

Can I use it for storage and transport, not just riding?

Yes. The waterproof, roll-up sealed construction makes it well suited to daily riding, travel, and long-term battery storage.

How does it mount to my ebike?

Hook-and-loop straps wrap around most bike racks, so it installs and removes in seconds without any tools.
