Lehmann Marine

Lehmann Marine is a global leader in delivering innovative solutions for the electrification and decarbonization of the maritime sector.
Based in Germany, the company develops cutting-edge products such as the water-cooled COBRA and the air-cooled CUBE.
Both systems are modular lithium-ion battery solutions, offering flexible options depending on vessel requirements.
These systems deliver high performance, certified safety, and exceptional installation flexibility, enabling vessels to reduce emissions and improve operational efficiency.

All Lehmann Marine battery systems are based exclusively on inherently safe LFP (lithium iron phosphate) cell chemistry, ensuring maximum safety, long cycle life, and environmental compatibility.
Lehmann Marine’s portfolio of safe, compact energy systems is well established in the maritime industry. The bestselling product remains the CUBE, which is now type-approved by BV, DNV, Lloyd’s Register, and RINA.
A fully electric ferry, several fish farm support vessels, river cruise ships, and crew transfer vessels are just a few of the recently commissioned references using CUBE power systems. Safe and compact LFP battery systems are in high demand, and Lehmann Marine is well positioned to meet this demand with the next step in its product evolution: high-power 2C LFP battery systems, offering even greater performance while maintaining the company’s commitment to safety and reliability.

The company stands out for its customer-centric approach and technical expertise, supporting integrators, shipowners and shipyards in the energy transition process.
Its team of experts ensures continuous assistance, from the initial design phase to after-sales service, guaranteeing that each project is carried out according to the highest standards of quality and safety.

Starting in May 2025, Stelio Bardi Marine Technologies has been appointed as the official agent of Lehmann Marine for Italy and Monaco, strengthening the brand’s presence in these strategic markets and ensuring even more direct and tailored support.
Lehmann Marine is committed to contributing to a more sustainable future for the maritime industry by delivering solutions that combine technological innovation, reliability, and environmental responsibility.
