Germany-based Lehmann Marine, a market leader in maritime lithium ferrophosphate battery systems, proudly announces that its safe and compact energy storage solution, CUBE, has been type-approved by Lloyd’s Register. This prestigious certification marks the fourth major classification society to approve the CUBE battery system, following Bureau Veritas, DNV, and RINA approvals.

The Lloyd’s Register type approval further underlines Lehmann Marine‘s flexible battery modules‘ reliability, safety, and quality, paving the way for broader adoption across the maritime industry. With this latest certification, shipbuilders, operators, and integrators are set to have even greater confidence in the CUBE system’s compliance with stringent industry standards.

“We are honoured to receive this recognition from Lloyd’s Register,” said Alexander Lehmann, Managing Director of Lehmann Marine. “This next milestone underscores our commitment to delivering high-quality, safe, and sustainable battery solutions to the maritime sector. We want to express our gratitude to the experts of Lloyd‘s Register for the smooth cooperation they have shown during the certification process.”

CUBE provides a modular lithium iron phosphate (LFP) battery design with superior energy density. Any power storage scale 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 and pre-charge functionality. The battery system excels with a superior energy density, being able by design to be stacked flexibly for optimum use of space. CUBE is a modular system with a very compact design and incorporates an innovative air-cooling technology that ensures uniform cooling of all cells for the highest cycle life.

With type approvals granted by BV, DNV, LR, and RINA, alongside the expansion of production facilities due to a strategic partnership with the Sunlight Group, Lehmann Marine’s CUBE is exceptionally well positioned to meet the strong demand from the shipping industry for safe and compact energy storage solutions.

New goals are established and clearly visible for the CUBE battery system. Lehmann Marine’s project team is endeavouring to secure additional type approvals from international classification societies like the Japanese ClassNK certification to unlock even more market opportunities.
