Lehmann Marine has introduced AQUBE, a marine battery system based on lithium-iron-phosphate(LFP) cells. This technology is designed to offer a continuous charge and discharge rate of 2C, enabling high-power applications on large vessels.
The LFP AQUBE battery with better performance and liquid cooling
With the backing of the Greek Sunlight Group, Lehmann Marine strengthens its global production capacity, projected to reach 300 MWh per year. This alliance also provides access to an international technical support network with more than 200 specialized engineers.
Derived from the CUBE and COBRA models, AQUBE integrates an adaptable modular format with proven cooling technology. In addition, its design allows for easy integration into confined spaces, facilitating its use on ferries, OSV ferries, OSVs and river vessels. The system supports scalable configurations up to 1000 VDC, with an architecture that includes BMS, precharge and custom switching.
The LFP cells cells offer advantages over chemistries such as NMC, especially in terms of thermal safety. In the event of a leak, the system releases gas without generating a fire, making it an ideal choice for offshore applications where reliability is critical.
AQUBE is designed under DNV and ESTRIN standards, allowing to create a reliable option for marine electrification projects. Delivery of the first systems is scheduled for mid-2026, elevating Lehmann Marine’s offering in the segment of safe and compact batteries for the marine sector.
