A DAME Award Winning marine battery that delivers extreme Lithium-ion performance even in the harshest conditions, by combining Lithium-Iron Phosphate (LiFePO4) cells with a proprietary Battery Management System (BMS) inside a sturdy, waterproof housing.

Mastervolt's sophisticated battery management system ensures optimal use of each cell, providing you with accurate and up-to-date information on the state of your battery. Furthermore, integrated NMEA2000, CZone and MasterBus communication allows complete system integration to ensure the best possible charging, whilst maximizing the lifespan of your battery.

The marine battery is equipped with a self-learning balancing algorithm that predicts the behaviour of each individual battery cell and balances proactively, resulting in a faster and more efficient charge cycle. The system eliminates unnecessary stress on the cells, further extending the Battery Cycle Life.

Mastervolt MLI battery has an integrated head-pad and sophisticated low temperature control, ensuring maximum charging performance, even at freezing temperatures. In cold weather, the marine battery uses the connected charger to power the heat-pad and keep the battery cell temperatures above freezing point. This ensures the fastest possible charging and full power capabilities, even on the coldest days.

An integrated battery switch safely disconnects the battery cells in case of any abnormalities. This is based on smart algorithms analysing all the details of the battery condition such as charge current, temperature, cell details and more. Where other integrated switches have current limitations, Mastervolt's MLI Ultra battery will keep providing continuous energy.

Installing a Lithium-ion battery has never been easier. Wire the marine battery to any supported Mastervolt charger, connect the communication cable, and the battery automatically fully configures the charger to match the battery. This way, a smooth and worry-free charging experience is ensured, without the need of any configuration tools.
