1. 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
▪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 - 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.

User manual PowerXtreme X20/X30
E18-X20X30-EN00 www.emergoplus.com Page 5of 25
▪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 is equipped with Bluetooth technology that allows
monitoring of the battery and switching it on and off via an App.
The PowerXtreme X30 does not have Bluetooth technology, but has a
capacity indication by means of LEDs on the housing.

3. Description and Operation
3.1 LiFePO4 battery for caravan mover
The battery has more than enough capacity to carry out 2 normal
displacement operations of a caravan. With heavy use (35 A continuous)
you can use the mover for up to 60 (X20) or 75 (X30) minutes. With extreme
use (100 A) you can use the mover for approx. 18 (X20) or 24 (X30) minutes.
After each operation, it is recommended that you charge the battery for
another operation.
The battery is suitable for briefly (approx. 10 sec) delivering very high
currents to overcome a threshold or other obstacle. If you try to do this for
a longer period of time, the battery will switch off automatically and you
should wait until the battery resets itself.
3.2 Charging
When the battery runs out, it must be recharged. Connect the charger to the
battery and then plug it into the 230V socket. The charger now starts
charging with a charging current of 2A.
During charging, the LED lights red.
At the end of the charging cycle the LED lights green.
The battery capacity can be read by pressing the thickener in the foil. One,
two or three green LEDs will light up as a rough indication of the charge
status. When the battery is empty, a small red LED lights up.
Figure 1. SOC Indication on battery

User manual PowerXtreme X20/X30
E18-X20X30-EN00 www.emergoplus.com Page 10 of 25
The charging time depends on the charging status at the start of the
charging cycle. If the capacity is still 40%, 6Ah must be charged. The
charging time is then around 3 hours x 2A + around 1 hour = around 4 hours.
The charger can be continuously connected to 230V, even after the battery
is fully charged. Never charge the battery pack at temperatures below 0°C.
At -10°C, a protection device is activated which makes charging impossible.
The battery can be discharged or used up to a temperature of -20°C.
The battery can also be charged by solar panels if they are connected to a
charger that is suitable for charging LiFePO4 batteries. We have the
XS20/XS20s MPPT Solar charger in our program. Because of the MPPT
technique this charger gets the maximum efficiency from your Solar
panels.
You can also charge the battery while driving. For this you need to use a so-
called charge booster, see paragraph 3.4.
3.3 PowerXtreme App
Via the Apple store (suitable for iPhone 4S with IOS 6 or higher) or the
Google Play store (suitable for Android 4.3 or higher) you can download the
PowerXtreme App and use it to read the status and health of your battery.
When you open the APP a dialog box appears where you can see all
Bluetooth devices within the range (< 5.0 metres). You can recognise your
battery by the serial number that starts with EP..... Select your battery, then
connect via Bluetooth and you will see all the information about the battery.
The following data is displayed in the APP:

PAY ATTENTION!
It is possible that the app displays a value that is
too low for the SOC (charge status) when the
battery has not been used for a longer period of
time. Once you have charged the battery, the SOC
display will be correct again.

right charging voltage for the PowerXtreme battery. Due to the limited
charging current, there is no need to install thick wiring. The XC3 also acts
as a battery guard. If the terminal voltage of the starter battery is too low,
the XC3 switches the battery off so that the starter battery does not
discharge further. Charging with a solar panel is also possible. However, a
suitable charge regulator must be used for this.
3.5 Storage
If you want to store the battery for a longer period of time, disconnect the
battery terminals. This will prevent the battery from being discharged by
slumber consumption. Also disconnect the charging current connector
from the battery. The battery has a very low self-discharge and can be
stored for up to half a year without any problems. Charge the battery after
half a year.
3.6 Installation
The following is important for the installation of the battery:
▪In the box, you will find the following parts:
-Battery with charger mounted inside
-Battery terminals + and –
-Mounting plate with Velcro and 4 self-tapping screws

▪Use proper cabling of sufficient cross-section and correctly
dimensioned terminals and battery terminals. Tighten all
connections securely. Recommended tightening torque for M6 is
9.9 - 14 Nm. Do not use too great a tightening torque, as this can
lead to irreparable damage to the LiFePO4 battery.
▪If you use screws to connect consumers instead of the supplied
battery terminals, make sure that these screws are not longer than
10mm.
CAREFUL!
If bolts that are too long are used, the connections
will not get stuck! This leads to large contact
resistances and can cause the battery or equipment
to spark or switch off.
