Victron Cyrix-li-ct 12/24V-230A Intelligent Li-ion Battery Combiner

On this page

When it comes to managing multiple batteries in your vehicle, boat or off-grid system, having a reliable and efficient battery combiner is essential. The Victron Cyrix-li-ct 12/24V-230A Intelligent Li-ion Battery Combiner offers an advanced, microprocessor-controlled solution that ensures your batteries are charged and managed optimally without the drawbacks of traditional isolators.

The Victron Cyrix-li-ct is a heavy-duty relay designed to intelligently connect and disconnect batteries based on their voltage levels. Unlike conventional diode isolators, it uses a microprocessor to monitor battery voltages and automatically link batteries in parallel when charging, then isolate them to prevent unwanted discharge.

This product is especially tailored for lithium-ion batteries, making it ideal for modern setups that demand efficient charging and battery protection.

Key Features of the Victron Cyrix-li-ct 12/24V-230A

  • Microprocessor control: Enables smart switching between batteries depending on their charge status.
  • Voltage-based operation: Connects batteries once voltage reaches a preset threshold and disconnects below float voltage.
  • Minimal voltage loss: Unlike diode isolators, the Cyrix-li-ct introduces virtually no voltage drop, improving charging efficiency.
  • Heavy-duty relay: Supports currents up to 230A, suitable for demanding applications.
  • 12V and 24V compatibility: Works with common battery systems used in Australian vehicles and marine environments.
  • Designed for Li-ion batteries: Optimised for lithium-ion chemistries ensuring battery longevity and safety.

Why Choose the Victron Cyrix-li-ct 12/24V-230A Battery Combiner?

Battery management can be tricky, especially when you have multiple batteries in your system. Traditional diode isolators waste energy and may cause inefficient charging due to voltage drops. The Victron Cyrix-li-ct overcomes these issues, making it a practical choice for Australian conditions where reliability and performance are critical.

Benefits at a Glance:

Efficient Charging

The Cyrix-li-ct avoids the voltage drops typical in diode isolators, allowing alternators and chargers to deliver full voltage to your batteries for faster and more complete charging.

Automatic Operation

The intelligent microprocessor automatically connects and disconnects batteries based on real-time voltage levels, requiring no manual intervention.

Prolonged Battery Life

By preventing over-discharge and unwanted current flow between batteries, the Cyrix-li-ct helps extend your batteries’ lifespan, especially important for lithium-ion setups.

How Does the Victron Cyrix-li-ct Work?

The device monitors the voltage of connected batteries continuously. When one battery reaches a pre-set voltage threshold indicating charging (usually above float voltage), the combiner automatically closes the heavy-duty relay to connect the batteries in parallel. This allows the charging current to flow from one battery to the other, ensuring both are charged efficiently.

Once the voltage drops below the float level, signalling that the batteries are discharging, the relay disconnects them to prevent draining one battery through the other.
