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.
