E-Bike Battery
E-bike batteries follow the standard lithium watt-hour limits, but most exceed the 160 Wh ceiling in practice and can't fly on a passenger aircraft at all.

Carry-on details
Allowed with conditions — but rarely in practice. An e-bike battery is a spare lithium battery and follows the same tiered rule as any other: up to 100 Wh unrestricted, 100–160 Wh with airline approval, over 160 Wh banned outright. The problem is that typical e-bike batteries run 300–600 Wh, several times the absolute ceiling — most e-bike owners will find their battery simply isn't allowed on a passenger flight, full stop, regardless of approval requests.
Checked-bag details
Not allowed. Like any spare lithium battery, an e-bike battery can never go in checked baggage.
Quantity limit
100 wh (per item)
Special instructions
If you need your e-bike at your destination, common alternatives are shipping the battery separately via a hazmat-certified carrier, renting a compliant battery locally, or checking whether your specific model has an optional smaller, travel-compliant battery under 160 Wh.

FAQ
- Can I get airline approval for my e-bike battery?
- Only if it's 160 Wh or under. Most e-bike batteries run 300-600 Wh, well past the ceiling airlines can approve — there's no approval pathway for batteries over 160 Wh on passenger aircraft.
- How do I fly with my e-bike if the battery can't come?
- Common options are shipping the battery separately through a hazmat-certified freight carrier, renting a battery at your destination, or checking if a smaller, travel-compliant battery is available for your model.
