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.
