The PowerXtreme X75/X125 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 X75/X125 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 X75/X125 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.

User manual PowerXtreme X75/X125
E18-X75X125-EN00 www.emergoplus.com Page 5of 25
▪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 X75/X125 are equipped with Bluetooth technology that
allows monitoring of the battery and switching it on and off via an App.

contact with the electrolyte, rinse it immediately with plenty of water.
After this, consult a doctor.
▪Use cables of the correct cross-section and keep the cable connections
as short as possible. Use reliable cable clamps and tighten the bolts
firmly.
▪Never short-circuit the + and - poles. The internal BMS is protected
against short circuits, but to prevent dangerous sparks this is strongly
discouraged.
▪Never connect the battery pack in series or in parallel with any other type
of battery pack.
▪Do not use the battery as a starter battery.
▪Do not open the battery pack. The guarantee is void if the battery is
opened.
▪Do not place the battery pack in a high temperature environment or in
direct sunlight or near a heat source >45°C.
▪Never install the battery in rain or damp conditions with RV>80%.
▪Avoid damage to the battery and/or charger housing.
▪Do not store the battery in discharged condition (< 11.5V) for a longer
period of time.
▪If the battery is stored for a longer period of time without use, we
recommend that you charge it once every six months. Don't forget to
disconnect the battery terminals or turn off the ground switch when you
don't use the battery for a longer period of time.
▪Never charge the battery pack at temperatures below 0 °C.
▪Always use the supplied charger. This charger is suitable for LiFePO4
cell chemistry with the corresponding charging voltage.
▪Never use a damaged battery pack.
▪Make sure that the battery and charger are never covered with clothing
or other materials! This can lead to overheating!
CAREFUL!
Using a charger that is not suitable for LiFePO4
chemicals can damage the battery because it is not
properly charged.

2.3 Transport alert
▪The Li-ion battery must be transported in its original packaging.
▪The X75/X125 batteries have been tested according to the UN handbook
for tests and criteria, part III, paragraph 38.3 (ST/SG/AC.10/11/Rev.5).
During transport, the battery falls under category UN3480 class 9,
packing group II and must be transported in accordance with these
regulations. This means that the battery must be packed in accordance
with the packaging instruction P903 for transport over land or sea (ADR,
RID & IMDG) and in the case of air transport (IATA) in accordance with
the packaging instruction P965. The original packaging complies with
these instructions.
▪Make sure that the battery is properly secured during transport. The
battery can become a projectile if a vehicle is involved in an accident.

3. Description and Operation
3.1 LiFePO4 battery for camper use
The X75 and X125 are excellent for use as a household battery in your
motorhome. As mentioned before, the capacity can be used for 100%,
which saves you the necessary space and weight compared to a lead-acid
battery.
The X75 and X125 are completely maintenance-free. You do not need to
keep the battery powered during the winter months. The self-discharge of
the battery is so low that it can be stored for at least 6 months without
recharging.
The battery can be connected to the EBL of the camper, provided that it has
a connection option for this. Make sure that the battery has the correct
charging voltage, see next section on charging.
3.2 Charging
When the battery runs out, it must be recharged. Use a charger with a
lithium charging characteristic (CC-CV). 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 XS20s
MPPT Solar charger in our program. Because of the MPPT technique this
charger gets the maximum efficiency from your Solar panels.
CAREFUL!
Stop the charging process if the battery becomes
too hot during charging (> 45
°C –50 °C).

User manual PowerXtreme X75/X125
E18-X75X125-EN00 www.emergoplus.com Page 10 of 25
You can also charge the battery while driving. For this you need to use a so-
called charge booster. The charging booster converts the available
charging voltage into the 14.6V required for the LiFePO4 battery. This
charging voltage is necessary because at lower voltages¹ the battery will
not be charged to 100%. We recommend installing the Xenteq Inverter 12-
12VDC 20A/40A Charge booster.
You can also charge with a 230VAC charger when using the mains. We
recommend for the X75 a charger with a charging current of 10 - 15A and
for the X125 a charger with a charging current of 15 - 20A.
Note 1:
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
PAY ATTENTION!
The charging voltage of the vehicle alternator
for Euro5 and Euro6 engines is often lower than
12V. This is done deliberately to ensure that the
charging status of the starter battery does not
exceed about 80%. The reason for this is that
the starter battery must always have charging
capacity available to store the energy
generated during regenerative braking.
This explains the need for a charging booster in
order to charge the household battery
optimally.

3.4 PowerXCharger XC3 (OPTIONAL)
To charge the battery while driving, the PowerXCharger XC3 is available as
an option. This converts the charging voltage of the car alternator into the
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
-Battery terminals + and –

▪Switch off all loads and charging equipment before you start
connecting.
▪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.
