The MLI Ultra series is designed to be able to enjoy all the best properties of Lithium Ion technology in the harshest conditions (high charge/discharge currents, wet environment, mechanical shock or vibrations).

All the advantages and integrated safety

MLI Ultra batteries bring two things on top of a selection of the finest Lithium-iron phosphate cells: a sturdy, waterproof housing and the best Battery Management System (BMS). The BMS includes active cell balancing for optimal use of each individual cell, even during fast charge and discharge, integrated battery monitoring to always have the best information on the state of your battery. Last but not least, it has MasterBus communication to the Mastervolt battery charger to ensure the best possible recharging and lifetime of the battery.

Lithium Ion has many advantages over lead acid, meaning the MLS series can fast recharge in an hour, and deep cycle (up to 80 % discharge) 2000 times without damage, which is three times longer than lead acid.

• Saves up to 70 % in space and weight.
• Three times the lifespan of traditional batteries (2000 cycles).
• Fast charging up to half an hour.
• High discharge rate up to 3C.
• MasterBus communication with every Mastervolt battery charger.
• Integrated Battery Management System (BMS) with active balancing.
• Integrated battery monitoring (Ah consumed, state of charge).
• Series balancing technology optimizes string connection.
• Tested and certified according to UN38.3.
