To better understand the capacity of a battery, it is easier to speak in Amperes.
On the standard boat there are no lithium batteries but 3 gel batteries of 220 ah for a total of 660ah. You should not discharge gel batteries below 60%, beyond that it damages the batteries irreversibly. In the end, the usable amperes on the standard gel batteries of the boat is about : 660Ah x 0.4 = 264Ah
The battery option includes two lithium batteries of 3,000W (=230Ah), so a total of 460Ah. The lithium batteries can be discharged up to 10%. In the end, the usable amperes on this battery pack is 460 x 0.9 = 414Ah
It is possible to add a third lithium battery of 3000W (230A), which finally gives 690 x 0.9 = 621Ah
Finally, we can also install 2 batteries of 6,000W (460Ah) for a total usable ampere of 920 x 0.9 = 828Ah.
MLI Ultra 12/6000
Heavy Duty, Ultimate Performance
The MLI series delivers ultimate 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 NMEA 2000, CZone or MasterBus communication allows complete system integration, to ensure the best possible recharging, 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.
