MLI Ultra 12/1250
Heavy Duty, Extreme Performance
The MLI series deliver extreme Lithium Ion performance even under the harshest conditions, such as high charge and discharge currents, wet environments, mechanical shocks or vibrations. This is realized by combining our best Lithium-Iron Phosphate (LiFePO4) cells with a proprietary Battery Management System (BMS) inside a sturdy, waterproof housing.
The sophisticated Mastervolt BMS ensures optimal use of each individual cell. Integrated battery monitoring provides you with accurate and up-to-date information on the state of your battery. Integrated NMEA2000, CZone and MasterBus communication allows complete system integration, to ensure the best possible charging, while maximizing the lifetime of your battery.
Self-learning balancing algorithm
The MLI Ultra batteries are equipped with a self-learning balancing algorithm that predicts the behavior of each individual battery cell and balances proactively, resulting in a faster and more efficient charge cycle. The self-learning system eliminates unnecessary stress on the cells, resulting in an even longer Battery Cycle Life.
Freezing cold weather performance
The MLI Ultra 1250 comes with integrated thermal heat-pad and sophisticated low-temperature control to ensure maximum charging performance at freezing temperatures. In cold weathers it uses the connected charger to power the heat-pad and keep the battery cell temperatures above freezing point. This assures the fastest possible charging and full power capabilities even on the coldest days.
Integrated battery switch
The integrated battery safety switch disconnects the battery cells in case of abnormalities. This is based on smart algorithms analyzing all details of the battery condition such as charge current, temperature, cell details and more. Where other integrated switches have current limitations, the MLI Ultra 1250 will keep providing energy up to 200 Amps continuously.
Plug-and-play by Auto Configuration
Installing a Lithium Ion battery has never been easier. Wire the MLI Ultra 1250 to any supported Mastervolt charger, connect the communication cable and the battery automatically fully configures the charger to match the battery. In this way a smooth and worry-free charging experience is ensured without the need of any configuration tools.
