Mastervolt MLI Ultra 12/2500 Rechargeable Lithium Ion Battery

MLI Ultra 12/2500

The MLI series is designed to be able to enjoy all the best
properties of Lithium Ion technology in the harshest conditions
(high charge/discharge currents, flooded environment, mechanical
shock or vibrations). To do this, the MLI batteries bring two
things on top of Lithium-iron phosphate cells: a sturdy, waterproof
housing and the best Battery Management System (BMS). The BMS
ensures optimal use of each individual cell, even during fast
charge and discharge, and has integrated battery monitoring to
always have the best information on the state of your battery. Last
but not least, it has MasterBus/CAN communication to the Mastervolt
battery charger to ensure the best possible recharging and lifetime
of the battery.

Features:

• Top performance, heavy duty Lithium Ion batteries.
• Ideal for running heavy loads for long periods and short charge
  times.
• Saves up to 70 % in space and weight.
• Three times the lifespan of traditional batteries.
• High cycle efficiency.
• Fast charging up to half an hour.
• High discharge rate up to 3C.
• MasterBus/CAN communication with every Mastervolt battery
  charger.
• Integrated Battery Management System (BMS).
• Integrated battery monitoring (Ah consumed, state of
  charge).
• Series connection up to 10 batteries possible.
• Waterproof electronics cabinet.
• Extremely safe LiFePO4 chemistry.
• Tested and certified according to UN38.3.

         

CAUTION!
For additional safety, Mastervolt
stipulates the use of a safety relay as mandatory part of the
battery installation. Mastervolt provides 12- and 24-volt models,
so you can always opt the correct voltage.
