3. INTRODUCTION
3Lion is the innovative NDS battery, built with the reliable Lithium Ferro Phosphate
Technology (LiFePO4) , which combined with the integrated BMS and 3Link system
(BMS Manager), delivers the best per ormance in the services ield due to the
advanced energy system.
Lithium technology provides signi icant advantages over traditional lead batteries
(AGM, GEL, Free Acid). For example, it can withstand high charging currents, with
a very high e iciency (or very low current dissipated during that phase), which
implies a much better charging speed. It does not su er rom the typical sul ation
o lead batteries, it has a very low sel -discharge rate (less than 3%/month), which,
combined with a 60% weight reduction and a large number o cycles (over 2500), it
guarantees more autonomy and remarkable savings in various areas.
The 3Lion dialogues only with the 3Link , which becomes the heart o the energy
system. All the positive aspects o the vehicle's system: Engine Battery, 3Lion
battery and all electrical equipment, so as not to strain the electrical system, are
connected to the 3Link which acts as a BMS manager. This allows or a better
charge management while driving by the alternator, achieving maximum current up
to 75A (depending on the alternator), reducing charging times, and thus achieving
greater autonomy during stops. Once the engine is turned o , the 3Lion service
battery is able, via the BMS manager ( 3Link ), to deliver current or all on board
electrical equipment: lights, heating, co ee machines, etc ... The LiFePO4
technology used or the 3Lion , unlike the traditional Li-Ion or LiPO, is extremely
sa e and reliable over time due to its special eatures. The BMS Manager ( 3Link )
dialogues with the touch screen display that shows all available in ormation about
the state o the battery, the charging system and on-board power consumption
systems.

4. INSTALLATION
To properly install the device, follow the instructions below.
4.1 INSTALLATION OF 3 Link
The 3Lion-3Link system o ers maximum per ormance i supported by a suitable
capacity alternator. It is recommended that the alternator be greater than or equal to
120A with an no-load voltage between 13.8V and 14.7V . No-load measurement means
the voltage measured at the terminals o the engine battery, when the engine is on, the
engine battery is charged or partially charged when all the electrical equipment on
the vehicle is o (lights, conditioner, etc.) and when the services battery is
disconnected rom the system.
Prepare an area for housing the 3Link box , as close as possible to the 3Lion , and to the
engine battery, but never in the engine compartment or in compartments that are not
protected from atmospheric agents . Remove the two screws in the front (highlighted in red
in the following figure), lift the cover and pull it out to allow convenient access to the
connection points.
Attach the base of the 3Link to a wall or floor of the housing selected for installation; use
the 4 self-tapping screws in the appropriate holes on the bottom of the base (highlighted in
yellow in the following figure).
4.2 MOUNTING SCHEME:
Be ore installing, make sure the vehicle engine and the battery charger are o . Do not
make junctions on the cables, make direct connections.

6Connection with display
The original, electrical system of the motorhome can be represented in a basic manner by a
relay that connects the engine battery (and thus the alternator) to the service battery when
the vehicle has the engine switched on (i.e. the alternator is in operation and signal D+ is
active). Below is a representation:
The installation of the 3Lion + 3Link is very simple, just intercept in the original system
of the vehicle, the cable that goes from the service battery to the control unit or to the
battery combining relay which in the figure " Original system of the camper " is identified
by number 05. Disconnect cable 05 from the service battery positive terminal, and connect
it to pin 2 of the 3Link .
Make other connections, as shown below.

For connecting the cables to pins 1, 2 and 3 of the 3Link, it is strongly recommended that
you use the terminals for M8 screws (DO NOT use the "fork" type) to ensure a perfect and
secure connection between the cable and the contact of the 3link, as in the following
figure.
1233 4

For connexions 01, 02 and 08, it is recommended the use 35mm 2 cross-section cables, if
the length of the connexion is less than or equal to 1 meter. If the length of the connexion
exceeds 1 meter, it is recommended the use of cables with a cross-section of 50mm2. It is
also advisable to install a 200A fuse on cables 01 and 08.
Tighten the terminals firmly to screws 1, 2, and 3 of the 3Link , with the supplied nuts
and washers.
Connections 03, 04, 05 and 06 are usually already present within the vehicle. If not present,
it is recommended to use cables with a section greater than or equal to 10mm 2 .
Connection 07 can be done with cable the cross-section of which is between 1mm 2 and
2.5mm 2 .
As soon as the ground cable is connected to the 3Link, the system becomes operational.
Charge completely just after installing the system or after doing any maintenance on
it. When it is fully charged, the display will show 100% on the battery state of
charge (SOC) display.
Close the 3Link cover by threading the two tabs on the back into the appropriate base
seats; tighten the 2 screws supplied into the holes at the front corners of the cover.

5. Attach the display to the back cover:
The 3Link touch screen allows you to interact with the device by easily selecting various
functions.
To properly use the touch screen, follow the instructions below:
Do not exert too much pressure on the surface of the display with your fingers and
do not use sharp objects. Doing so may damage the device or cause it to
malfunction.
Do not put the display in contact with other electrical devices.
Electrostatic discharges can cause malfunction.
Do not put the surface of the display in contact with water. The touch screen may
not work properly in the presence of moisture or if exposed to water and other
liquids.
For best performance, touch the touch screen with your fingertip.
You can use plastic stylus pens or a more accurate touch on the display, but it
is important that they do not have a sharp tip which can damage the sur ace.
5. OPERATION
The 3Lion + 3Link system allows for the automatic management and display of the
battery status. By means of the display, you can interact with the system and show all the
information such as voltage, current (charging with positive "+" sign, and discharging with
negative sign "-"), and state of charge. The state of charge (SOC) is indicated with coloured
lines ranging from red, indicating that the battery is low, to green, indicating that the
battery is charged.
The advanced 3Link BMS, when it becomes aware that the alternator is operating, it
activates the battery charge intelligently, obtaining maximum current up to 75A (depending
on the alternator characteristics), resulting in a reduction of charging times, and therefore,
greater autonomy during stops. All without overloading the cell system, which is actually

excluded when it is charging, from the passing of current to the 3Lion.
The amount of current that can be charged to the battery is closely related to the type of
alternator installed on the vehicle. The higher its power, the greater the amount of current
that the 3Link can draw from it. Alternator powers below 120A are not recommended, as
the battery's fast charge capacity will not be fully exploited.
Immediately a ter per orming all connexions, the system starts up and several
screens or setting the system parameters appear on the display as shown below.

The system settings screens are displayed at start-up and each time you press
and hold or at least 3 seconds the "Setting" key.
Once the key has been pressed, the main screen appears as shown below.
The state of charge (or SOC) indication as soon as the system is installed is purely
indicative, it becomes operational as soon as a full charge of 3Lion is performed.
When it is fully charged, the display will show 100% on the battery state of charge
(SOC) display.
In the lower left part of the screen, information about the 3Lion battery is shown.
Specifically, the battery state of charge is reported in 2 modes: textual, by means of the
percent value of the SOC, and graphically by the colouring of the notches inside the battery
symbol. The notches are coloured red, orange and green indicating respectively a fully
discharged, a partially charged or a fully charged battery. When the 3Lion is at the
charging phase, a thunderbolt is displayed overlapping the coloured notches.

Pressing inside the battery symbol, the 3Lion battery indications change shape as shown in
the following example.
In fact, the voltage and current values for the 3Lion are displayed. The current can take
negative values, that is, battery discharging, and positive values, that is, battery charging. In
the latter case, the thunderbolt symbol is displayed, overlapping the notches of the battery.
You can keep this view active by clicking on the "Setting" button and then checking the
following phrase: " Always show V and I ".
The engine battery indicator box always shows the voltage value of the battery, and if the
system is being charged by the alternator, the icon of the arrow turns red.
Below is a summary of the icons shown on the display:

Ah of the 3Lion, language.
In order to preserve battery from discharging, after 2 minutes of inactivity the display will
decrease its brightness. After 15 minutes, it will shut off. Just touch it to turn it on and
resume normal use.
The system is protected against excessive discharge or overload, however, it is
recommended that the battery voltage does not fall below 10.5V and does not exceed 15V.
If the 3Lion voltage is less than 11.5V, charge the battery immediately.
Before storing the 3Lion, it is recommended that you turn off the display. It is also
recommended to leave the battery fully charged. If the 3Lion is not used for a long time,
even if the self-discharge is very low (less than 3%/month), it is advisable to check at least
once every two months that the remaining amount of charge is greater than 0% and that
the voltage is greater than 12.8V. Otherwise, fully charge the battery.

5.1 CHARGE
It is recommended to use LiFePo4 lithium battery chargers. However, you can use a mains
battery charger for AGM/GEL batteries, checking that the maximum voltage supplied by it
does not exceed 14.5V. The charger must NOT perform any desulfation action. The use of
battery chargers for flooded lead acid batteries , although they can completely charge 3lion
batteries, they can reduce their life. If you have a configurable charger, set the CC/CV
(constant current/constant voltage) option, by setting the current value equal to or less than
0.5C, or 50A for the 3L-100, 3L-100B, 3L-100-P models, and 75A for the 3L-150-P model,
and the end--of-charge voltage value to 14.4V.
When the battery is fully charged (the display shows 100%), it is recommended that you
disconnect or turn off the charger. In the case of alternator charge, this is automatically
managed by the 3Link. In fact, 3lion batteries do not need maintenance like lead-acid
batteries.
.52 DISCHARGE

Discharge at constant current o 200A: 20 seconds maximum*;
* Measurements performed at an ambient temperature of 20 °C, and starting temperature of
the lithium battery of 20 °C.

6. OPERATION CHECK
Once the system is installed, you can test its functionality by performing the following
tests:
1) With the engine switched off, and with all the equipment powered off, check that the
voltage shown on the display relative to the 3Lion battery, is equal to the voltage
measured with the tester positioned on the 3lion poles (tolerance of ± 0.15V).
2) With the engine switched off, and with all the equipment powered off, check that the
voltage shown on the display relative to the engine is equal to the voltage measured
with the tester positioned on the engine battery poles (tolerance ± 0.15V).
3) With the engine switched off, turn on some pieces of equipment on the vehicle, and
check that a negative current is displayed on the display. With the ammeter clamp,
placing it on the wire out of pole 3 of the 3Link, it is also possible to verify that the
current shown on the display is the same as the current displayed on the instrument
(tolerance ± 10%).
4) With all equipment powered off, turn on the engine and verify that the engine battery
voltage rises to between 13.8V and 14.8V. If voltage remains below 13.8V, the engine
battery is likely to be discharged and/or the alternator has an abnormality or, if a
positive current is shown on the display, it indicates that the 3Lion battery is charging
and, in this case, skip to step 5.
5) If the 3Lion battery is not fully charged, and if the check in step 4 has been
successful, check the display for a positive current, and check that the arrow pointing
to the engine battery turns red. With the ammeter clamp, placing it on the wire out of
pole 3 of the 3Link, it is also possible to verify that the current shown on the display
is the same as the current displayed on the instrument (tolerance ± 10%).
7. VERIFIABLE PROBLEMS
If the 3Lion battery has a voltage between 0V and 10V (resulting voltage, also detected on
pins 2 and 3 of 3Link ) , it may be possible that the BMS protection inside the battery has
been operated. This protection occurs for three main causes:
1) Battery voltage has fallen below 10V (e.g. due to excessive discharge).
In this case, provide the 3Lion with a charging source (for example, via external charger,
alternator, etc.).
2) The battery voltage has exceeded 15V (e.g. due to an anomaly of the charger, or
because of some piece of electronic equipment in the system that enters a voltage
greater than 15V).
As soon as the 3Lion detects a voltage below 15V, it resumes working normally.
3) The battery is overheated.
You have to wait for the internal temperature of 3Lion to drop below the safety threshold.
It is difficult to estimate the reactivation time, as it depends on external conditions and the
degree of overheating.

4) The indication of the amount of available charge (SOC) does not seem to be accurate
or has suddenly indicated a value of less than 5%.
Run a full charge of 3Lion , where full charge means 100% shown on the battery state of
charge (SOC) display.
