Victron Cyrix-Li-Intelligent Charge Relay 24/48V-230A

DESCRIPTION

Victron Cyrix-Li-Charge 24/48V-230A: Intelligent Charge Relay for LiFePO4 Battery Systems

Precision Charge Control for Victron Lithium Battery Installations

The Victron Cyrix-Li-Charge 24/48V-230A is a microprocessor-controlled intelligent charge relay designed to integrate seamlessly with Victron VE.Bus BMS and LiFePO4 lithium batteries. It provides a reliable secondary layer of protection by managing the connection of high-current chargers, preventing cell overvoltage and over temperature conditions that can compromise battery lifespan and safety.

Unlike generic contactors or solenoids, the Cyrix-Li-Charge actively monitors both the BMS control signal and system voltages, ensuring chargers are only connected when safe. This reduces the risk of lithium battery damage and improves overall system reliability in 24V and 48V off-grid, marine, and automotive applications.

How the Cyrix-Li-Charge Protects Your Investment

In a Victron lithium system, the VE.Bus BMS acts as the primary safeguard. However, not all chargers can be directly controlled by the BMS. The Cyrix-Li-Charge bridges this gap by acting as a remote-controlled switch that engages or disengages the charger based on BMS commands and voltage thresholds.

  • Immediate disconnection when the BMS signals cell overvoltage or high temperature, preventing irreversible cell damage.
  • Automatic reconnection with a 3-second delay once conditions normalise, minimising downtime.
  • Voltage-sensing logic ensures the charger is only connected when it is actively producing charge voltage (27.4V or 54.8V), avoiding unnecessary cycling.
  • Built-in transient voltage suppression protects against voltage spikes during disconnection, safeguarding sensitive electronics.

Key Features and Benefits

  • High continuous current rating: 230A at 24V, 80A breaking capacity at 48V, suitable for large charger banks and inverter/chargers.
  • Low power consumption: Draws less than 4mA when open, preserving battery charge during storage.
  • IP54 protection: Resistant to dust and water splashes, ideal for engine rooms and exposed installations.
  • LED status indicator: Provides clear visual feedback on relay state (engaged, disengaged, connecting, alarm).
  • Compact and lightweight: 65 x 100 x 50mm, 0.27kg, easy to mount in tight spaces.
  • 3/8"-16 (Approx. M10) stud terminals accept heavy-duty lugs for secure, low-resistance connections.

Engineered for Demanding Environments

The Cyrix-Li-Charge is built to withstand the rigours of mobile and marine installations. Its sealed design (IP54) and robust terminals ensure reliable operation despite vibration, humidity, and temperature fluctuations. The included 1-metre control cable simplifies connection to the VE.Bus BMS, reducing installation time and potential wiring errors.

For system designers and installers, this relay eliminates the need for complex external control circuits, providing a plug-and-play solution that maintains the integrity of Victron's lithium ecosystem.

Applications

  • Marine lithium battery systems with high-output alternators or shore power chargers.
  • Off-grid solar installations using Victron inverter/chargers and MPPT controllers.
  • RV and caravan power systems requiring automated charge disconnect for lithium batteries.
  • Industrial backup power where battery safety and longevity are critical.

WARRANTY

Victron Energy Limited Warranty Policy

Direct Customers

Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.

End-Users

Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the original end-user, with a maximum of 66 months from the Victron Energy invoice date.
