By the end of 2022, the management team of the former COBRA battery division of Becker Marine System took the opportunity to enter the maritime market under the new name Lehmann Marine. The water-cooled COBRA system was well received by first customers, and the market asked for further developments. In 2023, the product range was extended by the air-cooled battery system CUBE, and the company resettled in larger facilities by moving from Winsen to Seevetal–Hittfeld.

Lehmann Marine provides all-in-one development, design, and production services, proudly carrying the "Made in Germany" seal of quality. The company's location in Seevetal-Hittfeld, just south of Hamburg, offers excellent transportation connections and ideal conditions for meeting the high standards required to supply innovative, emission-free battery systems for clean shipping.

The company provides a range of exciting opportunities for new employees and seeks dedicated, passionate individuals with innovative ideas to help steer the maritime industry towards a more sustainable, environmentally friendly direction.
