The 3Link unit must be installed with the 3Lion battery to get the full advantage of the fast
charging techno logy. However, a 3Lion battery can also be installed as a direct
replacement for a lead acid battery in a caravan for example.
A 3Lion battery can be installed with a maximum inclination of 90° compared to the
normal position (i.e. with the poles facing up).
Do not bump, puncture, disassemble or damage the 3Lion and the 3link. Do not attempt to
open the 3Lion battery.
In the event of electrolyte leakage, do not touch the battery. In case of contact, immediately
flush skin with warm water and seek medical advice immediately.
Be careful when installing, so that the two poles of the 3Lion do not come in contact with
each other. Use isolated equipment and do not place and/or leave metal objects close to
the product.
Always dispose of the battery according to local laws.
Protect the poles of the 3Lion from any contact with electrically conductive objects.
The 3Lion must be protected from direct sunlight or direct heat sources to avoid
overheating.
Do not install the appliance in a sealed environment, otherwise it may overheat.
Make sure that there is air circulation in the area where it is installed.
To avoid the risk of electric shock and/or fire, make sure the power supply is in good
condition.
Do not use the appliance with damaged cables and/or of inadequate cross-section.
Do not use the device in an environment with high humidity or direct contact with splashes
of water and/or liquids or in the rain.

section "INSTALLATION INSTRUCTIONS"
Fully charge the battery right 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).
The rated voltage of the 3Lion battery is 12 V. Do not use the system with devices that are
not compatible with this voltage. The company is not responsible for any damage, either
to the equipment or the vehicle caused by incorrect use of the entire system.
3. Introduction
3Lion is an innovative NDS battery and charging system, based on Lithium Ferro Phosphate
Technology (LiFePO4). Combined with the integrated BMS and 3Link system (BMS Manager), a
3Lion battery reliably delivers the exceptional performance that is available from a LiFePO4
battery.
Lithium technology provides significant advantages over traditional lead batteries (AGM, gel & wet
lead acid). For example, a 3Lion battery can withstand high charging currents which results in a
much faster charging speed. It does not suffer from the typical sulphation of lead batteries, it has a
very low self-discharge rate (less than 3% per month), and there's as much as a 60% weight
reduction over a comparable lead-acid battery. With a large number of cycles (2,500+ depending
on usage), it provides greater autonomy without the need for mains hook-up.
The 3Lion battery works in conjunction with the 3Link, which becomes the hub of the energy
system. The engine battery, 3Lion battery and al l electrical equipment, are connected to the
3Link. This allows the system to work efficiently and to achieve maximum charging - up to 75
Amps depending on the alternator - from the alternator when the engine is running. When the
engine is turned off, the 3Lion battery will deliver current for all on-board electrical equipment :
lights, heating, coffee machines, etc.
The 3Link unit communicates with the touch screen display and provides useful information about
the state of the battery, the charging system and how much energy is being used at any given
time.
The LiFePO4 technology used for the 3Lion, unlike other lithium batteries such as Li-Ion or LiPO,
is extremely safe and reliable.
3Lion batteries can be used almost anywhere that a lead-acid leisure battery is being used and, in
almost every case, a 3Lion battery will give significant advantages. However, the fast charging and
discharging abilities of the battery are dependent on the ability of the charging methods being
used.
Before installing any LiFePO4 battery, it's essential to check the output of the vehicle's alternator,
230V mains charger and, if used, the solar regulator, generator and fuel cell.
If any of these charge in a way that is not compatible with a LiFePO4 battery, performance will be
impaired and the battery could be damaged. In short, all charging methods must ensure that the
battery is not charged at more than 14.5V, does not have a “maintenance” mode where the
voltage is in excess of 13.8V or any “de-sulphation” mode.
If a LiFePO4 charging option is available (on most Votronic products, Sterling battery chargers and
NDS products for example) always select it. If a LiFePO4 charging option is not available,
selecting gel or AGM will also charge the battery without risk of damage but not to 100% state of
charge.
When installing 2 3Lion batteries in parallel, use only one 3Link and place the 2 3Lion batteries in
parallel with cables of a cross-action of at least 35mm2 and place them as close to each other as
possible. Proceed with the installation as shown in the diagram below.
4.1 Installation of the 3Link hub
The 3Lion / 3Link system offers maximum performance when used with an alternator rated at 120
Amps or more and with a no-load voltage between 13.8V and 14.7V. No-load voltage is measured
at the terminals of the engine battery, when the engine is on, the engine battery is fully charged, all
the electrical equipment on the vehicle is off (lights, wipers, air-conditioner, etc.) and when the
leisure battery is disconnected from the system.
Find a clean, dry, ventilated place to install the 3Link box, as close as possible to both the 3Lion
battery and the engine battery. Never install the 3Link in the engine compartment.
Remove the two screws in the front (highlighted in red in the photo), lift the cover and remove it to
allow convenient access to the connection points. Attach the base of the 3Link to a secure surface
(horizontal or vertical) using 4 self-tapping screws in the appropriate holes on the bottom of the
base (highlighted in yellow in the photo).
4.2 Connecting the cables to 3Link
Before installation, make sure that the vehicle engine and the battery charger are off. Do not make
joins in the cables, always make direct connections.

6 Connection to display
The original electrical system of the motorhome can be represented in a basic manner as a relay
that connects the engine battery (and thus the alternator) to the leisure battery when the vehicle’s
engine is on (i.e. the alternator is in operation and signal D+ is active). As shown here:
The installation of the 3Lion + 3Link is very straightforward.
1. Identify the original cable that goes from the leisure battery’s positive terminal to the split
charge relay or the existing electrical control box - here shown as ”Central unit or Parellator
relay” with cable connection number 05.
2. Disconnect cable 05 from the leisure battery positive terminal, and connect it to terminal 2
of the 3Link.
3. Connect the engine battery’s positive terminal to the 3Link terminal 1 with 35 mm² sq cable
via a 200A fuse. If the vehicle has a battery-to-battery charger then connect the positive
output of the charger to 3Link’s terminal 1. (See note below on battery-to-battery chargers &
smart alternators)
4. Connect the 3Lion battery’s positive terminal to the 3Link’s terminal 3 with 35 mm² cable.
5. Connect 3Link’s terminal 5 to the chassis with 1mm² cable.
6. Connect the cable linking the 3Link to the display.
7. Lastly connect the 3Lion battery’s negative terminal to the vehicle’s chassis using 35mm²
cable.
The diagram below shows the completed installation in a vehicle with a conventional
alternator and without a battery-to-battery charger.
NOTE !!
The 3Lion battery will work with any type of alternator including "smart" alternators. But, if your vehicle is equipped
with one of these, you will have to install a battery-to-battery charger if the battery is to be charged efficiently. This is
not a difficult job but, depending on which model you use, the connections to the 3Link may vary.
1. If your engine is fitted with a standard alternator (not smart) connect the cable from the positive terminal of the
starter battery to the 3Link terminal 1.
2. If your engine is fitted with a smart alternator and you are using an NDS Power Service Gold unit as a battery-
to-battery charger, connect the cable from terminal 6 of the Power Service Gold to terminal 2 of the 3Link.
(See diagram below.)
3. If your engine is fitted with a smart alternator and you are using a battery-to-battery charger from CTEK,
Sterling, Votronic or another manufacturer, connect the cable from the positive terminal of the starter battery
to the 3Link terminal
2.
4. Note that, if your vehicle does not have a smart alternator but is already equipped with a battery-to-battery
charger, to get the full benefit of a 3Lion battery you must remove the charger completely.
The diagram below shows the completed installation in a vehicle with a smart alternator and NDS
Power Service Plus / Gold charging system.
The diagram below shows the completed installation in a vehicle with conventional alternator and
NDS Power Service Plus / Gold charging system.
The diagram below shows the completed installation in a vehicle with a smart alternator
and a battery-to-battery charging system such as those supplied Votronic, NDS & Sterling.
In all installations, for connections 01, 02 and 08 it is recommended that you use 35mm² cross-
section cables, if the length of the connexion is 1 meter or less. If the length of the connection
cable exceeds 1 meter, cables with a cross-section of 50mm² should be used. It is also advisable
to install a 200A fuse on cables 01 and 08.
Connecting cables 03, 04, 05 and 06 are usually already present within the vehicle. If not present,
or less than 10mm, it is recommended to use cables with a section of at least 10mm².
Connection 07 can be made using cable with a cross-section of between 1mm² and 2.5mm².
For connecting the cables to terminals 1, 2 and 3 of the 3Link, you must use ring
terminals for M8 screws - as shown here - to ensure a perfect and secure
connection between the cable and the contact of the 3link. DO NOT use the "fork"
type of terminal.
Tighten the terminals firmly to screws 1, 2, and 3 of the 3Link, with the nuts and
washers supplied.
As soon as the ground cable is connected to the 3Link, the system becomes
operational.
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.
After installing the system, or doing any maintenance on it, discharge the
3Lion battery completely. Then fully charge it. When it is fully charged, the
display will show 100% on the battery state of charge (SOC) display.
If the LCD display shows that the 3Lion’s battery has a voltage above 12.7V
but the state of charge reads 0%, discharge it completely and then recharge it
to 100%. This will allow the system to calibrate itself.
