Our advanced marine battery systems are powering the next generation of electric and hybrid maritime vessels, helping to reduce their environmental impact and improving sustainability, while also assisting with regulatory requirement compliance. On port-side, our charging and battery energy storage systems (BESS) enable fast charging whilst also reducing the demand on the harbour grid by acting as a buffer.

    Navius MRS-3 Marine Rack System

    The Navius MRS-3, is Leclanché latest generation of marine battery system, specifically designed for the supply of on-board energy storage in marine applications.

    It comprises the latest generation Leclanché M3 Energy battery modules fitted with our proprietary high energy G/NMC cells, a Functionally Safe Battery Management system and is assembled into a scalable and modular rack system. This new design enables the Navius MRS-3 to be configured to fit efficiently into the available space on nearly any vessel.

    It is an evolution of the successful and well proven Leclanché MRS-2 system
    which is powering vessels around the world.

    The Navius MRS-3 battery system utilises liquid-cooling for more efficient
    thermal management, a longer system lifetime and high performance in
    a compact footprint.
