Victron Cyrix-Li-ct 12/24V-230A Lithium Battery Combiner Relay

The Victron Cyrix-Li-ct 12/24V-230A is a smart battery combiner that enables parallel connection between lithium iron phosphate (LiFePO₄) batteries and lead-acid starter batteries. Designed for 12V and 24V systems, it operates based on voltage sensing and signals from a VE.Bus Battery Management System (BMS), ensuring safe and automated engagement or disconnection.

Key Features:

Automatic parallel connection when voltage and BMS conditions are met
Supports both 12V and 24V battery systems
High continuous current rating: 230A
Built-in transient voltage suppressor to protect from voltage spikes
Disengages immediately on overvoltage or overtemperature signal
Start-assist function: manual 30-second close pulse
LED status indication for real-time relay state
Control cable included (1 meter)

Electrical Specifications:

Parameter	Value
System Voltage	12V / 24V
Continuous Current	230 A
Engagement Voltage	> 13.4 V / 26.8 V
Disengagement Voltage	< 13.2 V / 26.4 V
Control Signal	VE.Bus BMS – High: Engage / Floating: Disengage
Power Consumption (open)	< 4 mA
Protection Rating	IP54
Weight	0.27 kg (0.6 lbs)
Dimensions (HxWxD)	65 x 100 x 50 mm (2.6 x 4.0 x 2.0 in)

Functional Description:

Engages when:
- VE.Bus BMS charge disconnect output is high
- Voltage > 13.4V (12V system) or > 26.8V (24V system)
Disengages when:
- Control input goes floating (e.g., overvoltage or overtemperature)
- Battery voltage drops below 13.2V / 26.4V
Transient voltage suppression included to limit disconnection spikes
LED indications:
- On: engaged
- 10s flash: disengaged
- 2s flash: connecting
- 0.25s blink: alarm (e.g., overtemperature or low battery)

Applications:

This relay is ideal for integrating lithium batteries into traditional lead-acid starter systems, especially in marine, RV, off-grid solar, and mobile applications where seamless transition and BMS-controlled automation are critical.
