Lithium ion batteries have a high energy density and are perfect for cyclic applications. They offer savings of up to 70% in volume and weight compared to traditional lead-acid batteries, with three times as many charging cycles (2000 full cycles).
Another major benefit of the Mastervolt Li-ion battery is that it is equipped with a Battery Management System (BMS), which automatically compensates for any imbalance between the cells. This guarantees you a constant high capacity and longer battery lifespan. The Lithium Ion Ultra series includes integrated battery monitoring.
Having perfected the legendary Lithium Ion battery in a few key areas, Mastervolt has developed an unrivalled 2500 or 5000 Wh powerhouse.
The MLI Ultra has an ultra-long lifespan that offers over 2000 cycles at 80% DOD; a potential recharge time of less than an hour; active cell balancing for efficient and safe use of the Li-ion cells; and integrated battery monitoring to further simplify your system.
What’s more, the Ultra communicates directly with your Mastervolt battery charger via MasterBus to ensure the best possible recharging. Add in the fact that it takes up 70% less space and weight compared to lead acid batteries, and you’ll see why this battery is the best choice.
The Mastervolt Li-ion battery is equipped with an integrated Battery Management System with active cell balancing. Ensuring that the available energy is automatically divided between cells guarantees efficient and safe functioning of the battery.
As speed and performance are crucial aspects, a Lithium Ion battery – which takes up 70% less weight than similar lead acid batteries – offers considerable benefits. A vessel or vehicle with a capacity of 20 kWh on board, can easily save up to 500 kg and achieve a substantially better performance.
Mastervolt Lithium Ion batteries have a realistic lifespan of over 2000 cycles at a depth of discharge (DOD) of 80%. This is three times longer than lead acid batteries thanks to features such as battery management, the almost complete absence of self-discharge and the minimal build-up of the infamous ‘memory effect’.
The Lithium Ion Ultra batteries are ideal for electric and hybrid applications, and can be connected in parallel unlimited. The built-in common-rail technology offers an easy series connection of multiple batteries.
The elegant design of the Li-ion Ultra in the characteristic Mastervolt colours includes two integrated handles with a recess for the correct and practical installation of the cables. As the battery poles are easily accessible and completely protected, extra isolation covers are not needed.
