Mastervolt introduces the new MLI Ultra 12/1250 Lithium-Ion Battery.

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.

Mastervolt Reaches A Safety And Performance Milestone With UL 1973 Compliance

With an unwavering commitment to safety, quality, and performance, Mastervolt, an industry leader in
Lithium Ion Battery Systems for the Marine and Mobile markets, is proud to announce that it has
completed testing with the RVIA approved test lab, Testing Engineers International (TEI) to meet UL 1973
standards. This new certification, along with the long-standing ISO 9001 certification that Mastervolt
diligently maintains is evidence to Mastervolt’s dedication to the highest standards of safety and

With the growing popularity of lithium batteries, they were added to the 2020 edition of RV Industry’s
adopted American National Standards Institute (ANSI) Low-Voltage Standard. To be included in RV
products, lithium batteries must be listed by a third-party listing agency recognized by the RV Industry
Association. The TEI UL1973 compliance confirms that Mastervolt lithium ion batteries are compliant with
all of the RVIA requirements and with that the preferred customers choice.

“Continuous improvement and safety are the mainstays of our culture” stated Mara White, Senior Product
Manager. “Meeting the UL 1973 standard is an important milestone in the global development of our
industry leading energy storage systems”.

Mastervolt worked directly with accredited third-party testing group TEI to complete testing and achieve
TEI listing to meet UL 1973 standards. TEI’s certification confirms that Mastervolt’s MLI series of Lithium Ion
batteries meet or exceed important safety standards, as well as meeting the needs of end users.

“Optimizing the end-user experience and ensuring their safety is what drives us” stated White. “As we
continue to evolve our integrated power technology, maintaining critical standards is vital. This is why the
new certification mark is important, and will support our commitment to provide a friction-less end user
experience across all markets.”
