Product description
The PowerXtreme X20/X30 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:
Minimal weight
Small dimensions
Low internal resistance
High efficiency
Excellent cycle performance
Large permitted temperature range
Almost constant Voltage throughout the entire discharge cycle
Full capacity is usable
It is possible to use 100% of the capacity before the battery is empty and switches itself off. On the PowerXtreme
X20 this is 20Ah and on the PowerXtreme X30 is this 30Ah. 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 X20/X30 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 X20/X30 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
–
If the cells get under a certain voltage, the BMS will stop the discharging. You have to
recharge the battery as soon as possible.
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.
Too low temperature - The BMS prevents the battery from being charged at temperatures below -10°C.
Short circuit - The BMS switches the battery off if the terminals are shorted.
Our batteries have a cell balancing function built into the BMS. Because the cells are never 100% identical,
this system ensures that the cells remain balanced and that no major differences in cell voltages can arise
due to the discharge and charging.
The PowerXtreme X20 & X30 are equipped with a smart BMS with Bluetooth technology. After installing the
PowerXtreme app on your smartphone, you can read the state of charge, the status, the voltage, the number of
cycles, the temperature and the condition of your battery. It is also possible to turn your battery on and off via this
app.
