121 ft Yacht with 478 kWh COBRA Battery System
Compact 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.
Introducing the COBRA battery system
COBRA is an advanced and DNV type approved battery system employing inherently safe lithium iron phosphate (LFP) cell technology and taking the special requirements of maritime operation and classification into account. 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. The COBRA Battery System from Lehmann Marine is type approved by DNV and complies with the European Standard of Technical Requirements for Inland Navigation Vessels (ESTRIN).
