Do you want to bring the battery from your e-bike or cargo bike on a plane? Don’t just assume that’s allowed. Strict aviation regulations apply to lithium batteries. Therefore, before booking, check with your airline to see if they accept your specific battery under their terms and conditions. The situation is different when traveling by car: if you’re transporting the battery yourself for personal use, the ILT regulations for the transport of hazardous materials by road do not apply. In this article, you’ll learn why that’s the case and what you can do if your battery isn’t allowed on board.
Are you mainly concerned with transporting the bike itself? If so, read our article about Taking your cargo bike on vacation by car or trailer. This is purely about the battery.
Why are the rules for lithium batteries on airplanes so strict?
The short answer: a lithium-ion battery can overheat, and you don't want that to happen at an altitude of 10,000 meters.
The U.S. Federal Aviation Administration (FAA) explains that all lithium-ion batteries can overheat and enter a state known as “thermal runaway.” According to the FAA (accessed on October 21, 2026) This can happen without warning, for example, if a battery is damaged, has become too hot, has gotten wet, has been overcharged, or has been packaged incorrectly. A manufacturing defect can also be the cause.
That same source notes that lithium batteries must pass safety tests and that cabin crew are trained to respond to a battery fire. That says it all: aviation organizations take this risk seriously.
An e-bike battery is not a cell phone battery. For example, the STOER CargoX battery has a capacity of 960 Wh. Be sure to provide that capacity when you contact a carrier to find out what rules apply to your battery.
Car Battery or Airplane Battery: What's the Difference?
When traveling by car for personal use, different rules apply than when traveling by air. Check with your airline to see if you’re allowed to bring your battery on the plane.
The Human Environment and Transport Inspectorate (ILT) states that, when it comes to the transport of hazardous substances by road, private individuals must adhere to the same rules as businesses when having such substances transported, including for return shipments. If you transport hazardous substances yourself for your own use, the rules for parcel transport apply in accordance with the ILT (accessed on October 21, 2026) no.
The bar is set higher for air freight. Packaging instructions apply to the shipment of loose lithium batteries by air, and according to the ILT (accessed on October 21, 2026) You need approval from the ILT aviation authority to do so. This approval does not apply to batteries shipped in or with devices, such as laptops and phones, if this is permitted under the conditions of so-called Section II.
| Situation | What do you know? | What do you do? |
|---|---|---|
| Bring your own battery in your own car, for your own use | In that case, the ILT regulations governing the transport of hazardous materials by road do not apply. | Transport the battery safely in the car, and be mindful of temperature and damage. |
| Have a battery shipped as a package (even as a private individual) | According to the ILT, the same rules apply as for businesses. | Ask the supplier or carrier how to do it correctly. |
| Shipping a loose battery as air cargo | Packaging instructions and approval from the ILT aviation authority are required. | Don't count on being able to handle this on your own. |
| Bringing a battery as checked luggage on a plane | Based on the sources cited in this article, it has not been determined whether you are allowed to carry your battery as checked baggage. | Before booking, check with your airline to see if they accept your battery. |
Where can you check the current rules for your battery?
Always start with the party that is actually transporting your battery. Rules can change, so don't rely on what an acquaintance experienced last year.
- Your airline. Check to see if they allow your specific battery in the cabin or as checked baggage under their terms and conditions. Do this before you book, not at the airport.
- Your carrier or freight forwarder. Would you like to have the battery or bike shipped? Ask what their policies are for lithium batteries.
- The supplier or manufacturer of your battery. They know the specifications of your battery and how to return it or ship it safely, if necessary. The ILT also recommends asking the supplier for instructions when returning items.
When asking your question, please include the capacity of your battery (in Wh). That way, you'll get an answer that's specific to your battery.
Are you traveling by car through multiple countries? If so, be sure to check the rules for your destination and the countries you’ll be driving through in advance. This article does not cover foreign regulations, so please check those yourself using an official source.
What do you do if you're not allowed to bring your battery?
Can't take your battery on the plane? Then you have a few realistic options.
Choose road transport
If you're driving a car, you can keep an eye on the battery yourself. To find out how to transport the bike yourself, read our vacation article about cars and trailers.
Do not simply send the battery by mail
Putting a battery in a box and sending it by mail seems easy. But according to the ILT, the same rules apply to individuals as to businesses. So first ask the supplier or carrier how to do it correctly.
Leave your own bike at home
Sometimes the simplest solution is to leave your bike at home and rent one at your destination. That way, you don't have to worry about transporting the battery. Just be sure to carefully review the rental company's terms and conditions when you get there.
Here's how to prepare your battery if you do decide to bring it along
Are you bringing the battery with you in the car? If so, treat it with care. Damage, overheating, and contact with water are factors that the FAA cites as possible causes of thermal runaway.
- Remove the battery from the bike before riding. The CargoX's battery is removable.
- Transport the battery in the car, not separately on a trailer.
- Never leave the battery in a hot car.
- Protect the contact points, for example, with tape.
- Bring the battery inside during breaks and store it at room temperature.
- Check the battery for dents, cracks, or water damage. If you're not sure, don't bring it with you.

Your next step
Are you planning to fly with your bike? If so, first check the capacity of your battery and provide that information to your airline before you book. If the airline doesn’t allow you to bring the battery, you’ll still have time to consider traveling by car or renting a bike at your destination.
