Compact and safe marine LFP battery systems
Marine batteries as energy storage and power supply for propulsion significantly reduce fuel consumption, maintenance costs and emissions. With improved capacity-to-weight ratio from lithium-ion technology and growing demand for lower emissions, batteries have become an ever-increasingly attractive option for the large-scale supply of energy in the maritime sector.
The compact COBRA battery system
COBRA is an advanced battery system employing inherently safe lithium iron phosphate (LFP) cell technology and considering the special requirements of maritime operation and classification. Any scale of power storage is available by freely configuring modular units in standardised racks of up to 1,000 V DC including efficient water or air-cooling and a battery management system. COBRA is type-approved by Bureau Veritas, DNV and RINA and complies with the European Standard of Technical Requirements for Inland Navigation Vessels (ESTRIN).
The flexible CUBE battery system
CUBE provides a modular design with superior energy density. The flexible energy storage is scalable from a few kWh to several MWh and allows for optimal use of room space. Any scale of power storage is available by freely configuring modular units in strings of up to 1,000 VDC. They include an integrated Battery Management System (BMS), gas exhaust, pre-charge functionality and sophisticated air cooling technology for safe and reliable operation.

About Lehmann Marine and battery systems made in Germany
With the founding of Lehmann Marine a new supplier of innovative maritime energy solutions such as the well-known COBRA and the new CUBE battery systems entered the maritime market in 2023. COBRA was developed by Becker Marine Systems and has now been incorporated into Lehmann Marine. The company is a subsidiary of the Family Office Höpen GmbH, which continues to be a shareholder in Becker and eCap Marine.
„After we pushed ahead with the development of COBRA at Becker over the past six years, the product stands on its own two feet,“ says technical director Godehard Gauf. And the demand in the maritime market for battery solutions is growing. „We are looking for more staff, especially for production at our location just south of Hamburg,“ says Alexander Lehmann, managing director of Lehmann Marine.
