January 30, 2025: The Sunlight Group said it aims to make waves in the maritime battery market by acquiring a 51% stake in Lehmann Marine in a “multi-million euro” deal.

The lead and lithium battery manufacturer said on January 20 it had signed the investment agreement with Lehmann, a member of Germany-based family-owned holding company Höpen. Financial details were not disclosed.

Sunlight said the deal came amidst increasing demand for sustainable shipping, including electric and hybrid propulsion systems.

Lehmann is a pioneer in development of LFP battery systems. The firms said their R&D teams will work together closely, with joint activities including shared procurement of lithium cells, production line automation, and cost optimization in design to boost competitiveness and accelerate production.

Sunlight CEO Labros Bisalas said: “By combining our expertise with Lehmann Marine’s, we are positioning ourselves at the forefront of the rapidly growing maritime battery market.”

Lehmann MD Alexander Lehmann said the move gave his company a powerful ally in the market, including opportunities to expand sales of its Cube and Cobra battery systems.
