About this product :

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). To do this the 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 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.
