1.3 Transport and storage
On storage or transport of the product, ensure that the battery leads are disconnected.
No liability can be accepted for damage in transit if the equipment is not transported in its
original packaging.
Store the product in a dry environment; the storage temperature should range from –20°C to
60°C.
1.3.1 Storage instructions of Lithium batteries
Store the Lithium batteries always fully charged.
Check the voltage of the stored Lithium battery periodically. If the voltage is dropped below
24V, recharge it. Because of the battery management electronics there is always a leakage
current which will eventually empty the battery. The weekly consumption of the BMS inside
a 24V/180Ah battery, when not connected to the Lynx Ion + Shunt, is approximately 2Wh
per week.
1.3.2 Storage instructions of a complete system (Lithium batteries with Lynx)
Lithium batteries will permanently damage when fully drained. The system has a small self-
discharge which needs to be taken into account when storing the system. It is best to
always store the batteries fully charged.
When storing a complete system, make sure that the Lynx Ion + Shunt is set in standby
mode (for instructions see chapter 6).
• Standby consumption 24V Systems: 73mW for the Lynx Ion + Shunt (standby).
• Standby consumption 48V systems: 139mW for the Lynx Ion + Shunt (standby).
Two calculation examples:
• A full single 24Volt battery connected to a Lynx Ion + Shunt which is in standby
will last approximately 2570 days. The same system, but then automatically
switched to standby mode due to under voltage will last approximately 128 days.
• A full 48Volt system with two batteries in series, connected to a Lynx Ion + Shunt
which is in standby will last approximately 2700 days. The same system which
has automatically disconnected and switched to standby mode due to under
voltage will last approximately 135 days.

2 DESCRIPTION
2.1 System components
•One or more 24V 180Ah Lithium-Ion batteries.
•The Lynx Power In. A modular dc bus-bar.
•The Lynx Ion + Shunt is the battery management system (BMS) that controls the
batteries. A 350/600 Ampere safety relay is inside the Lynx Ion + Shunt.
•The Lynx Distributor, a DC distr bution system with fuses.
•Optionally, the Color Control GX, a digital control panel.
2.1.1 Battery Management System
Every individual 24V/180Ah Lithium-Ion battery has an onboard Battery Management
System, which monitors and protects the battery on cell level. The Lynx Ion + Shunt
communicates with all battery packs via the BMS CAN-Bus and monitors the system as a
whole.
2.1.2 Safety
When designing the Victron Lithium-Ion battery system, a lot of thought was put into the
safety aspect of the system. Each battery is equipped with a BMS to monitor the
performance on a cell level. To monitor the global performance we have chosen the Lynx
Ion + Shunt. This serves as a master unit and controls the individual batteries. This way the
system as a whole can function at its best, ensuring a maximum return. The battery
differentiates itself from other batteries thanks to its safety contactor. This breaks the
connection between the battery and the rest of the system when the Lynx Ion + Shunt is
unable to disconnect the external equipment due to complications.
2.1.3 User interface: Color Control GX
The Color Control GX is a digital control panel for the system.

4.5 Connection of the BMS CAN-Bus network
To connect the BMS CAN-Bus communication network you will need:
• CAT5 cable with RJ45 connectors
• Two termination resistors (supplied with the Lynx Ion + Shunt)
Procedure
1. Use connection A of the Lynx Ion + Shunt, top left pair of RJ45 connectors.
Connect the other end of the CAT5 cable to the first battery.
2. Then connect it to the second battery (if there is one) with the next CAT5 cable.
3. Repeat this until all batteries are connected.
4. Place a termination resistor in the last connected battery.
5. Place the other termination resistor in the Lynx Ion + Shunt, connection A.
Now the BMS CAN-Bus network is connected.
4.6 Connection of the VE.Can network
The VE.Can network is used to connect the Color Control GX or other VE.Can devices such
as the BlueSolar Chargers. These chargers can be digitally controlled by the Lynx Ion +
Shunt.
To connect the Lynx Ion + Shunt to the VE.Can network you will need:
• One CAT5 cable with RJ45 connectors
• Two termination resistors (supplied with the Lynx Ion + Shunt)
Procedure
1. Use connection D of the Lynx Ion, the pair of RJ-45 sockets at lower left. Connect
the CAT5 cable to the Lynx Ion + Shunt, connection D (see Appendix A).
2. Connect the other end of the CAT5 cable to another VE.Can device such as the
Color Control GX.
3. Now place the termination resistors. One in the Lynx Ion +Shunt and one in the
other end of the VE.Can network.

4.8 Using the I/O of the Lynx Ion + Shunt
Allow-to-charge and allow-to-discharge
The most important contacts are ‘allow-to-charge’ and ‘allow-to-discharge’. These are used
to control loads and chargers based on the battery state of charge.
These contacts are potential free, and normally open. They are closed when the system is
normally working. If the battery is fully charged the ‘allow-to-charge’ contact will be opened.
Now the charger knows that it has to stop charging. If it does not stop charging, the safety
contactor will eventually open. This also applies for the ‘allow-to-discharge’ contact. It is set
open when the battery is fully discharged. All consumers have to stop discharging.
See appendix A, connection ‘C’ for the connections of the allow-to-charge and allow-to-
discharge contacts.
External status output
The external status output can be used for external indication similar as the status LED on
the front of the Lynx Ion + Shunt.
Two options are poss ble to connect the external status output.
•Connect a status indicator to connector ‘ B‘ pin 1 and 2. This output uses the
system voltage.
•Connect a status indicator to connector ‘C’ pin 8 and 9. This output uses 12V.
See appendix A for the connections details.
External Safety Contactor
See the next paragraph, 4.9.
The external safety contactor output can also be used as an alarm output. If the internal
contactor is opened this contact is set LOW(0V) else it is HIGH(system voltage).
External START-button
It is possible to connect an external START-button. This must be connected to pin 7 of
connector ‘C’. This pin must be switched to GND of the system (pin 9 of connector ‘C ‘ ). It
then has the same functionality as the START-button on the front of the Lynx Ion + Shunt.
Use a momentary switch button for this.

E
0% 100%
A
The batteries are discharged too low. The 350A safety contactor in the Lynx
Ion will open.
B
The batteries are discharged. The allow-to-discharge signal contact will open.
The Multi will switch to ‘Charger Only’, to prevent further discharging the
batteries.
C
OK. The Multi can both charge and discharge the batteries. The allow-to-
charge and the allow-to-discharge contacts are closed.
D
The batteries are full. The allow-to-charge contact will open. The Multi will
switch to float, to prevent further charging the batteries.
E
The batteries are almost over charged. The 350A safety contactor in the Lynx
Ion will open.
Condition A and E are error conditions. Proper configuration of the system will prevent these
conditions from occurring. When they occur, correct the situation, and press the start button
again to restart the Lynx Ion + Shunt.
Connections
To configure the Multi for BMS support, VEConfigure3 is necessary. See the Support &
downloads section at www.victronenergy.com for more information on installing
VEConfigure3 and updating the Multi to firmware version xxxx200 or higher.
1. Connect the allow-to-charge signal to the AUX input on the Multi.
2. Connect the allow-to-discharge signal to Temp sense input on the Multi. It is not
necessary to use a temperature sensor with the Multi, since the batteries have
their own internal temperature sensors.
3. Start VEConfigure3, and select the Lithium Iron Phosphate type:

4. Configure the Lynx-Ion BMS Support assistant as follows:

6 FIRST POWER UP
Other than below procedure, no configuration is needed. The battery configuration is
automatically recognized.
6.1 Power up procedure
1. Make sure that all energy consumers are switched off before starting up the
system.
2. The Lynx Ion + Shunt will pre-charge the system before closing the safety
contactor. The Lynx Ion + Shunt will not start if there is more than 10A drawn by
the system during pre-charging.
3. Press the START-button on the front of the Lynx Ion + Shunt to start the system.
4. Now the system is being pre-charged. The safety contactor is closed as soon as
the voltage rises above 80% of the battery voltage.
5. If the status LED is continuously on, then the system is running and ready for use.
6.2 Power down/reset procedure
Lynx Ion +Shunt to standby mode:
1. Press and hold the START-button until the Lynx Ion goes into standby mode
(status LED off).
2. Now the safety contactor is open and the batteries are disconnected from the
system.
Reset Lynx Ion + Shunt from error state:
1. Press the START-button for 1 sec.
2. The system will now restart.
6.3 Automatic power-up
The Lynx Ion + Shunt will automatically power-up from standby if a charge voltage on the
output is supplied for more than 10 seconds.

7 TEMPERATURE PROTECTION
The Lynx Ion + Shunt constantly monitors the battery temperatures, and protects them
according below rules. In case the temperature is outside the limits, it will first signal the
chargers and/or loads via the allow-to-charge and allow-to-discharge contacts. It will open
the safety contactor if there is no response. In that case you will see the LED blinking in the
specified error code ( see chapter 3 for details). Press the START-button to restart the
system.
High temperature signals:
•Stop charging and discharging at +60°C (allow-to-charge and allow-to-discharge
contacts open)
•Charge and discharge alarm at +65°C (safety contactor open)
Low temperature signals:
•Stop charging at -5°C (allow-to-charge contact open)
•Stop discharging at -20°C (allow-to-discharge contact open)
Alarm temperatures:
•Charging alarm at -10°C and current > 10A (safety contactor open)
•Discharging alarm at -25°C and current < -10A (safety contactor open)

8 MAINTENANCE
The Lynx Ion + Shunt does not require specific maintenance. It will suffice to check all
connections once a year. Avoid moisture and oil/soot/vapors, and keep the device clean.
