Victron Energy Integration Guide

How to connect your TITAN Lithium battery to a Victron GX device (Cerbo, Color Control, Venus, Ekrano, etc.).

Why use CANBUS?

Unlock the full power of your system. Connecting your TITAN Lithium battery to a Victron GX device isn’t just about monitoring - it’s about total system intelligence. By establishing a data link (CAN-bus), your battery takes control of your Victron system, automatically telling the inverter and solar chargers exactly what it needs.

  • 100% accurate state of charge (SOC): no more guessing or drift. The battery tells the system exactly how much energy is left.
  • Safety first: the battery automatically manages charge currents and stops charging if it gets too cold (engaging the built-in heater) or full.
  • Plug & play: designed to work seamlessly with Victron’s native BMS-Can protocol.
  • Automatic adjustments: when connecting multiple batteries in parallel, the system will automatically adjust available capacity, charge and discharge current allowances in real time.

What you’ll need

Before you begin, ensure you have the following components ready.

Victron Energy Cerbo GX and TITAN Lithium battery kit

  • TITAN Lithium battery with comms ports - any model in the current range.
  • Victron GX device - Cerbo GX, Color Control GX, Venus GX, Ekrano GX, or any GX-enabled inverter.
  • TITAN comms cable (RJ45) - in 1.8m, 3m or 5m lengths.
    • Standard ethernet cables look the same but rarely have the right pin-out for BMS data. Use the certified TITAN cable - the cables that ship with Victron equipment or generic ethernet runs will not work.

How to connect

Step 1 - Identify the ports

  • On the battery: locate the data ports on your battery (on the top for 230Ah+ or the side for 105Ah-180Ah). Find the port labelled RJ45-2 & RJ45-3.
  • On the Victron device: locate the ports labelled BMS-Can or VE.Can.

Step 2 - Plug in

  • Connect the labelled ‘To Battery’ end of the RJ45 comms cable into the battery’s CAN port.
  • Connect the labelled ‘To Inverter’ end into the Victron’s BMS-Can port.
    • Tip: on a Cerbo GX use the port specifically labelled BMS-Can (usually the middle pair). BMS-Can has been renamed on V2 Cerbos to VE.CAN.

Step 3 - Terminate the network (crucial for multiple batteries)

  • If you are connecting multiple batteries, daisy-chain them together first (battery 1 to battery 2, etc.) using normal CAT5 ethernet cables, and plug the Victron cable into the first or last free port in the chain.
  • Ensure the terminator (supplied with your battery) is plugged into the last remaining free port on the last battery, or use the Victron blue terminator (supplied with your Victron device) plugged into the second BMS-Can port on the Victron device, to close the data loop.

Victron console settings

Once plugged in, you need to tell the Victron device to listen to the battery.

  1. Open your Victron Remote Console or touchscreen.
  2. Navigate to Settings → Connectivity → VE.Can port → CAN-bus profile.
  3. Change the profile to CAN-bus BMS LV (500 kbit/s).
    • Do NOT select “VE.Can & Lynx Ion BMS” - this is for Victron’s own batteries.

Connect to Bluetooth

Once the menu is set, connect to the battery's Bluetooth via the TITAN Lithium app (see the TITAN App page for download links). This wakes up the comms section of the BMS so data can flow over both Bluetooth and the RJ-45 ports. You only need to do it once - a live connection on the comms ports keeps that section awake from then on.

Enabling DVCC (the brain)

Distributed Voltage and Current Control (DVCC) allows the TITAN battery to control the charging logic of the entire system.

  1. Go to Settings → System Setup → Charge Control → DVCC.
  2. Enable DVCC: turn this ON.
  3. Limit charge current (optional): if you have a small battery bank but a large current charge input, switch this on. The BMS will control how much current is allowed through the system.
  4. SVS (Shared Voltage Sense): turn this OFF. The BMS provides the most accurate voltage reading directly.
  5. STS (Shared Temperature Sense): turn this OFF. The battery monitors its own temperature internally.

Verification

If successful, the battery should appear in your Device List.

  1. Go to the main menu.
  2. Look for a device named Generic BMS or TITAN Lithium (depending on firmware version).
  3. Click on it. You should see live stats for voltage (V), current (A), state of charge (%) and temperature (°C).

Troubleshooting

  • Don’t see the battery? Check your cable type. A standard LAN cable often works for monitoring but may not allow full control. Ensure you are using the correct CANbus cable sold by TITAN, and that you have connected to the battery’s Bluetooth via the TITAN app to wake the comms section of the BMS.
  • System charging too fast? Double-check your DVCC settings and ensure “Limit Charge Current” is active if your charger exceeds the battery’s recommended max charge rate (see your battery label).
