The Imperium Lithium 105Ah is a Lithium-iron phosphate (LiFePO4) battery. This is the safest of
the most important lithium-ion battery types. Besides safety, the LiFePO4 technology is charac-
terized by:
•
Minimal weight
•
Small dimensions
•
Low internal resistance
•
High efficiency
•
Excellent cycle performance
•
Large permitted temperature range
•
Almost constant Voltage throughout the entire discharge cycle
•
It is possible to use 100% of the capacity before the battery is empty and switches itself off.
This is in contrast to lead-acid batteries where usually 50 - 60% of the capacity can be used
before the battery needs to be recharged.
Which makes the battery the right choice for a wide range of applications. Another big ad-
vantage compared to lead-acid batteries is that the LiFePO4 battery does not need to be fully
charged. A lead-acid battery will fail due to sulphating if it is not fully charged for a longer peri-
od of time. The Imperium Lithium battery consists of 4 cells connected in series with a nominal
voltage of 3.2V which together form 12.8V.
Essential part of the LiFePO4 battery is its Battery Management System (BMS). The BMS moni-
tors the cells that make up the battery for the following risks:
• Too deep discharge - A LiFePO4 cell will fail if the voltage is less than 2.5V. The BMS discon-
nects the battery before the cell voltage reaches this point.
• Overvoltage - If the cell voltage exceeds 3.65V during charging, the BMS will stop the higher
voltage. The BMS stops the charging process before the cell voltage becomes too high.
