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.

4System to fix the display frame to the cover
1. Remove the display frame.
2. Position the back cover on the wall chosen for installation. Take the point references
where the holes for the fixing screws (diameter 3 mm) and the communication cable
passage hole (minimum diameter 7.2 mm) are to be made.
3. Drill the holes and screw the back cover to the wall using the supplied screws. Be
careful that once tightened, the screws do not protrude beyond the countersinks.
4. Pass the communication cable through the specially-drilled hole and insert it gently
into the connector on the display circuit board.
DO NOT FORCE THE CONNECTOR.
The connector has an
obligatory direction that must be
ollowed.
A) Slide the display rame upwards
with respect to the back cover
B) Li t the lower part
o the display
rame
C) Slide the display rame
downwards with respect to the
cover and release it.

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
