2. Documentation
This User Manual provides information about the integration of Discover AES Lithium batteries with Victron Energy
devices in a Closed Loop conguration using the AES LYNK Communication Gateway with installed AES LYNK Edge
Card for Victron. AES battery can be use in Energy Storage System (ESS) for self consumption, Grid backup and Off-grid
applications.These instructions apply to an off-grid application.
Note that in a Victron networked system the charging variables will be managed automatically by the AES battery BMS and
the Venus GX / Color Control GX device. Discharging variables are managed by the set up of the Victron inverter.

3. Overview
3.1 System Overview
The AES LYNK Communication Gateway unlocks the full potential of a Discover AES LiFePO4Battery by enabling the
internal Battery Management System (BMS) to optimize the charge and discharge congurations of the world’s best inverter
chargers and solar charge controller systems in a closed loop conguration.
AES LiFePO4 batteries must be set up to work with Power Conversion and Monitoring devices in either an Open Loop or
Closed Loop conguration. AES LiFePO4battery charge and discharge settings in a Open Loop conguration are set up
manually through the controller for the Power Conversion device at the time of installation.This is commonly refered to as
a ‘lead acid drop-in replacement’ conguration. In a Closed Loop conguration the battery charge and discharge rates and
settings are dynamically controlled by the BMS of the AES LiFePO4 Battery over a connection with the power conversion
devices in the network.
To connect with the communication network of a specic brand of inverter charger or solar charge controller, the LYNK
Communication Gateway requires an AES LYNK Edge Card with the appropriate communication port.
3.2 Minimum Battery Capacity
Battery charge and discharge rates are managed automatically by the AES LiFePO4Battery and Victron CCGX device. Using
very large solar arrays with battery banks that are too small can exceed the operating limits of the battery to charge and
possibly lead to the BMS triggering over-current protection. Battery capacity must be sized to accept the maximum charge
current of the system, or the the charging devices must be curtailed to charge below the operating limit of the installed
batteries.This value is derived by adding together the charge capacities of all inverter/chargers and solar charge controllers
in the system. Additionally, battery peak capacity must be sized to support the surge requirements demanded by the load
attached to the inverter. Match the sum of all inverter peak power values with the sum of all battery peak battery current
values.

4 Conguring Victron Products
4.1 VE.Congure Settings
You will need the latest rmware on all connected devices.This section presumes familiarity with VECongure software.
These settings are for an off-grid application.These parameters once set will become the default values used if
communication with the AES battery is interrupted for some reason. During normal operation the charge characteristics are
governed automatically by the CCGX via DVCC, with instructions from the connected AES battery. However it is necessary
to set the discharging parameters for DC input low shut-down found under the InverterTab. After setting the parameters,
‘send’ all parameters to the inverter and CCGX. Restart the CCGX after completion.

5. Installing LYNK and Connecting LYNK to the Victron Network
5.1 Installing the LYNK Edge Card
The LYNK Edge Card for Victron is a Slot 0Type which only inserts into the left side slot on the bottom of the LYNK
Communication Gateway.
▲NOTE
• The LYNK Edge Card type to be used is determine by the brand of power
conversion equipment.
• If LYNK Edge Card is in the wrong slot, it will not function.
• If LYNK Edge Card is not rmly seated, it will not function.
Slot 0 Type

5.2 Connecting LYNK to the AES Battery
Connect the AES LYNK Communication Gateway to the AES LIFePO4Battery and power up as described in the LYNK Communication
Gateway Users Manual.
▲ CAUTION
HAZARD OF EQUIPMENT DAMAGE
• Do not plug the AEBus RJ-45 cable terminator into the 10/100 Ethernet port
of the LYNK.
• Do not connect a CAT5 cable from the 10/100 Ethernet port of the LYNK to
the WAN or MODEM port of a network router.
• Turn OFF all devices before connecting cables or inserting an Edge Card.
Failure to follow these instructions can damage equipment.
▲ NOTE
• Power electronics are not AEBus devices and should not be connected
to AEBus.
5.3 Connecting LYNK to the Victron Network
Before connecting LYNK to the Victron Network ensure that the rmware for all Victron devices is up to date.
• MultiPlus / Quattro - version 459 or later.
• CCGX / Venus GX - version 2.32 or later.
• VE.Direct MPPT - version 1.42 or later.
▲ NOTE
• VE.Can MPPTs cannot be used and are not yet supported
Insert one end of a CAT5 communication cable into the LYNK Edge Card port and the other end into one (A) of the two
VE.Can ports (A-B) on the back of the Color Control GX (CCGX). Use the terminator provided with the CCGX to terminate the
network by plugging it into the second VE.Can port (B).

8discoverbattery.com
Using the CCGX navigate from the Device List > Settings > Services > Can-bus Prole and select VE.Can & CAN-bus BMS (250
kbit/s).
Return to the Device List and the CCGX should display Discover AES as one of the devices along with the battery SoC, Voltage
and Amps. If you have multiple batteries a single entry will show up, which represents all batteries.
▲ NOTE
• If Discover does not appear on the Device List, conrm that the CAT5
communication cable is a normal patch type and not a cross over type.
Use manufactured cables to avoid bad crimps and reduce the risk of a poor
connection.
The parameters option within the battery page shows the actual battery charge limits. If you have multiple batteries a single
entry will show up, which represents all batteries.
▲ NOTE
• Battery Low Voltage value displayed is the BMS value, the actual discharge
voltage limit is governed by the DC input low shut-down setting.

6. System Set Up
6.1 Synchronizing the Victron System with the AES Battery
Once the VE.Can and CAN-bus bit rate is set, communication of the AES battery parameters will be automatic.
During normal operation, the charge parameter limits are set by the BMS of the AES battery and communicated through the system
by the CCGX to the inverter/charger and MPPT.
To optimize performance of a Victron system the following items need to be manually set using the CCGX.
Navigate from the Device List screen > Settings > System Setup.
From the System Setup menu scroll down to select each item and then set as indicated.
• Battery Monitor: DISCOVER on CAN-bus
• DVCC - Distributed Voltage and Current Control: ON
• SVS - Shared voltage sense: OFF (7)
• STS - Shared temperature sense: OFF
• Limit charge current: ON
• Max charge current: Installed number of AES batteries x (42-48-6650: 92A < 130A) or (44-24-2800: 78 A < 110 A) (8)
(7) SVS should be set to OFF (there have been instances of conict reported by Victron Support when SVS is set to ON and used with a Lithium BMS).
(8) Limit charge current works across the whole system. MPPTs are automatically prioritized over the mains. In case the AES BMS requests a maximum charge
current that is different from the user-congurable setting, the lower of the two will be used.
▲ NOTE
• To avoid conicting network information and data, do not
use a Victron BMV battery monitor when using AES LYNK
Communication Gateway.
