Description
xCyrix-Li-load 12/24V-230A Intelligent Load Relay
The Victron Cyrix-Li-load is a microprocessor-controlled load relay designed for lithium battery systems operating at 12V or 24V. It disconnects non-essential loads when the battery voltage drops to a critical level, protecting the battery from deep discharge. Rated at 230A continuous, it suits demanding DC load circuits in marine, vehicle and off-grid installations.
Key Features
- Rated at 230A continuous current, suitable for high-draw DC load circuits.
- Compatible with 12V and 24V lithium battery systems, with voltage thresholds calibrated for Li chemistry.
- Microprocessor-controlled logic monitors battery voltage and disconnects loads automatically at a programmable low-voltage threshold.
- Reconnects loads once the battery has recovered to a safe voltage level, without manual intervention.
- Compact and lightweight at 0.3 kg, allowing installation in confined spaces.
- Works alongside Victron Battery Management Systems (BMS) and can be controlled via a BMS load disconnect signal.
Product Overview
The Cyrix-Li-load differs from a standard battery combiner in that it is specifically designed to protect lithium batteries from over-discharge by shedding loads rather than combining battery banks. When battery voltage falls below the disconnect threshold, the relay opens and isolates the connected load circuit. This is particularly important for lithium chemistries, which can be permanently damaged or rendered unsafe if discharged beyond their minimum cell voltage.
At 230A, the unit handles substantial DC loads including inverters, winches, bow thrusters and other high-current consumers. The microprocessor continuously monitors voltage and applies hysteresis to prevent rapid cycling at the threshold boundary. For installations using a Victron BMS, the Cyrix-Li-load can also accept a direct load disconnect signal from the BMS, giving the battery management system direct control over load shedding independent of voltage alone.
The 12/24V dual-voltage compatibility means a single unit covers both common DC system voltages, reducing the need to stock separate parts for different installations.

Installation Notes
Installation should be carried out by a qualified electrician or experienced marine/vehicle electrical installer. The Cyrix-Li-load must be wired in series with the load circuit, not the battery charging circuit. Ensure cable sizing is appropriate for the 230A continuous rating and that suitable fusing is fitted as close to the battery as practicable. When integrating with a Victron BMS, refer to the BMS wiring documentation to correctly configure the load disconnect signal. Lithium battery systems carry specific safety requirements; do not attempt installation without a thorough understanding of lithium battery management principles.
