The Victron Cyrix-Li-load 12/24V-120A (CYR010120450) is a robust solid-state relay designed for safely disconnecting loads in lithium battery systems managed by a VE.Bus BMS. Supporting continuous current up to 120A at 12V or 24V, it protects against undervoltage by disengaging loads when triggered by the BMS. With automatic reconnection logic and ultra-low power consumption (<4 mA), it is a reliable and efficient alternative to traditional high-draw mechanical relays.

Victron Energy Cyrix-Li-load 12/24V-120A – Intelligent Battery Load Disconnect Relay (CYR010120450)
The Cyrix-Li-load 12/24V-120A is an intelligent DC load relay tailored for Victron Lithium battery systems. It automatically disconnects and reconnects loads based on commands from a VE.Bus BMS, reacting to critical battery conditions like undervoltage. Its fast switching and self-learning reconnection logic ensure load safety without manual intervention. Ideal for mobile, marine, and off-grid applications, the Cyrix-Li-load significantly reduces idle current drain while maintaining reliable protection.
Main Features
- Designed for use with Victron VE.Bus BMS and LiFePO₄ batteries
- Rated for 120 A continuous current at 12V or 24V
- Intelligent control input: ON when high (battery voltage), OFF when floating or low
- Automatically disengages loads when battery voltage drops below safe levels
- Will attempt 3 re-engagements before requiring full recharge to reconnect
- Compact design with IP54 ingress protection
- Ultra-low idle current: <4 mA

Mechanical & Environmental
Parameter Value Dimensions (HxWxD) 46 × 46 × 80 mm Weight 0.11 kg (0.24 lbs) Protection Class IP54 Operating Temperature -20°C to +50°C Humidity Max 95% (non-condensing)
Integration Notes
- Connects to the Load Disconnect output of VE.Bus BMS
- Reengages only when battery voltage remains above 13V (or 26V) for at least 30s
- After 3 failed reengagement attempts, waits for full charge threshold before retrying
- Use BatteryProtect if lower standby power draw is a priority
Application Scenarios
The Cyrix-Li-load is ideal for disconnecting large DC loads in lithium-based energy systems. It acts as an automatic safety gate between the battery and downstream consumers, especially useful when the BMS needs to protect the battery from deep discharge. Perfect for campervans, yachts, or off-grid systems with sensitive lithium storage.
