1. Product description
The PowerXtreme X10 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 characterized by:
▪Low internal resistance
▪High efficiency
▪Small dimensions
▪Minimal weight
▪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. On the PowerXtreme X10 this is
10Ah. 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 this battery the right choice for a wide range of applications.
Another big advantage 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 period of time.
The PowerXtreme X10 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 monitors 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 disconnects 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.
▪Too high temperature - The BMS will turn off the battery if the
system temperature becomes too high.
