Important information on air transportation of lithium-ion batteries:
V-MAX², SOLO, SOLO+ and SERVO

22.10.2025

We would like to inform you of an important, short-term change to the air transportation of our V-MAX², SOLO, SOLO+ and SERVO lithium-ion batteries.

Previous regulation: The batteries mentioned contain several cells that are separated from each other by setting the flight mode. As a result, they were regarded as individual batteries, which may be transported in the aircraft below the permitted limit of 300 Wh. Based on this assessment, we had provided corresponding declarations of no objection (UBE) and letters of confirmation from the German Federal Aviation Authority (LBA) on our website.

Current situation: The LBA has withdrawn this decision with immediate effect. As the individual battery cells can be switched off separately, but are installed next to each other in a housing, the LBA has safety concerns, which is why the letter of confirmation is no longer valid. This also applies to devices that are in the field. Declarations of no objection that have already been downloaded lose their validity.


Important information for end customers:

  • No clearance declarations or LBA confirmation letters can currently be provided for the simplified transport approval route for the batteries mentioned.

  • However, this does not mean that the batteries may no longer be transported. The decision on transportation lies with the respective airline.

  • Nothing has changed with regard to the batteries themselves. They are still the proven, safe lithium-ion batteries, including the option of putting them into flight mode.

The BAM (Federal Institute for Materials Research and Testing) is currently working with the UN/IATA to examine whether the current power limit for these batteries can be adjusted. Unfortunately, a date for a change is not foreseeable.

We are actively working on finding a solution and positively influencing the regulation in the interests of our end customers.

If you have any questions or require further information, please do not hesitate to contact us at any time.
