Outstanding battery properties in series production

As a leading manufacturer with sites in Tübingen and Itzehoe, Germany, we produce battery cells with outstanding properties for the advanced air mobility sector.

They meet the highest requirements and have a high energy density, which makes them the central building block of the electrical transformation in the aviation sector.

Whether eVTOL, eCTOL or eSTOL, our batteries are paving the way for safe and certified applications in future aviation.

Battery cell supplier for well-known companies

Development of pouch and round cells

We are developing both: pouch and cylindrical cells for use in the eAviation sector.

Our commitment to safety and certification

Providing airworthy cells for eAviation

Exceptional standards
Qualitative workmanship
State of the art technologies

We meet the highest standards of quality and traceability with our production of lithium-ion batteries. We target design, product and manufacturing approval for eAviation.

As a premium brand, we guarantee battery cells with exceptional performance characteristics that also impress with a premium quality of workmanship.

CustomCells has established quality assurance processes along the entire supply chain, using the latest technologies to ensure the high quality of our work at every stage of production.

Digital technologies for safety and innovation

We are more than just a leading developer and manufacturer of lithium-ion batteries. CustomCells is also a digital pioneer and technological trailblazer in the battery industry. When it comes to high-performance cells, we are defining and shaping a completely new segment – today and in the future.

With the help of technologies such as machine learning, digital twins and artificial intelligence, we are continuously developing our processes and changing the boundaries of what is possible. Smart cell technology provides us with unique data directly from real-world cells, ensuring maximum safety and data-driven innovation.

Holistic approach for more sustainability

The ecological transformation of the aviation industry is one of the greatest challenges of our time. With our lithium-ion battery cells, we are paving the way for an era of sustainable and advanced air mobility.

We think of sustainability holistically – along the entire value chain. For us, this includes not only the sustainable use of materials, but also taking into account recycling and second-life approaches right from the development stage.
