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 easily fits batteries measuring 3 7/8" x 4 5/8" x 14" long, such as a 48V 20Ah pack, with room to spare to still fold the top closed, so it can handle even larger packs. A good rule of thumb: if you are storing anything bigger than a 48V 20Ah battery, the large bag is the safe bet, and if you are running a 52V pack, you should almost certainly go large. Those higher-capacity packs, like the 52V 19.2Ah battery in the Juiced Scrambler HT and Scrambler FS, are physically bigger and need the extra room. It is built for the wider and thicker packs found on many fat-tire and dual-battery ebikes. Not sure which size you need? If your battery is skinnier, up to about 3.5" x 3.5" in cross-section, 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.

Tested ebike large size battery bag compatibility

Below are batteries we have confirmed fit our large battery bag. If your battery is not listed, measure it (length x width x height) and compare before ordering.

• Lectric XP Trike battery
• Juiced Scrambler HT battery (52V 19.2Ah — requires the large bag)
• Juiced Scrambler FS battery (52V 19.2Ah — requires the large bag)

How to choose the right size battery bag

• Go large for wider, thicker packs. This bag easily fits batteries around 3 7/8" x 4 5/8" x 14" long, such as a 48V 20Ah pack, with room for even larger packs, and still folds the top closed. Great for many fat-tire and dual-battery ebikes.
• Bigger than a 48V 20Ah pack? Go large. Anything above that is a safe bet for this bag, and 52V batteries (like the 52V 19.2Ah in the Juiced Scrambler HT and FS) should almost certainly use the large size.
• Choose small for skinnier packs. If your battery is around 3.5" x 3.5" in cross-section, 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.

Do I need the large bag for a 52V battery?

Almost certainly, yes. 52V packs such as the 52V 19.2Ah battery in the Juiced Scrambler HT and Scrambler FS are physically larger, and in general anything bigger than a 48V 20Ah battery is a safe bet for the large 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.
