Victron Cyrix-Li-load 12/24V-230A: Intelligent Load Disconnect for LiFePO4 Battery Systems

Precision Protection for Your Lithium Battery Investment

The Victron Cyrix-Li-load 12/24V-230A is a specialised intelligent load relay engineered to safeguard LiFePO4 (lithium iron phosphate) batteries from damaging under-voltage conditions. Designed to integrate seamlessly with a VE.Bus BMS, this relay acts as a critical second line of defence, automatically disconnecting loads when cell voltages approach unsafe levels. By preventing deep discharge, it helps extend battery cycle life and maintain system reliability in mobile, marine, and off-grid applications.

Unlike generic voltage-sensitive relays, the Cyrix-Li-load responds directly to the BMS control signal, ensuring precise, cell-level protection rather than relying solely on overall battery voltage. This targeted approach reduces the risk of premature cell failure and the associated downtime or replacement costs.

How It Works: BMS-Driven Load Management

The Cyrix-Li-load engages when its control input receives a high signal (approximately battery voltage) from the VE.Bus BMS, allowing normal load operation. If the BMS detects an imminent cell under-voltage, it releases the control input, causing the relay to disengage and isolate the loads. This immediate response prevents further discharge and protects the cells.

After disconnection, battery voltage often recovers slightly. The Cyrix-Li-load will attempt to re-engage after a 30-second delay. If the under-voltage condition persists, it will try up to three times before locking out. To reset, the battery voltage must rise above 13 V (26 V for 24 V systems) for at least 30 seconds, indicating that charging has resumed. This intelligent logic avoids nuisance cycling while ensuring loads are only reconnected when safe.

Key Features at a Glance

  • 230 A continuous rating at 12 V or 24 V, suitable for high-demand DC loads
  • Direct BMS integration via included 1-metre control cable for precise cell-level protection
  • Low power consumption (<4 mA when open) to minimise drain on the battery
  • IP54 protection against dust and water spray, ideal for engine rooms and exposed installations
  • LED status indicator for at-a-glance monitoring of relay state and alarm conditions
  • Compact, lightweight design (65 x 100 x 50 mm, 0.27 kg) for flexible mounting
  • M8 stud terminals (approx. 5/16") accept heavy-duty lugs for secure, low-resistance connections

Built for Demanding Environments

With an IP54-rated enclosure, the Cyrix-Li-load resists dust ingress and splashing water, making it suitable for use in marine engine compartments, vehicle under-bonnet installations, and other harsh settings. The robust M8 stud terminals ensure reliable high-current connections, while the integrated transient voltage suppressor protects against spikes that can occur during sudden disconnection.

Applications: Where Precision Load Control Matters

This relay is essential in any LiFePO4 system where loads cannot be directly controlled by the VE.Bus BMS. Typical use cases include:

  • Marine and RV electrical systems – Protect house batteries from being drained by DC distribution panels, inverters, or other loads
  • Off-grid solar installations – Prevent over-discharge of lithium battery banks in remote power systems
  • Industrial and mobile equipment – Safeguard batteries in electric vehicles, forklifts, or portable power packs

For systems requiring ultra-low standby consumption, a Victron BatteryProtect may be considered as an alternative. However, the Cyrix-Li-load offers the advantage of bidirectional current flow and higher continuous current handling.

Installation and Compatibility

The Cyrix-Li-load is designed for straightforward integration with Victron VE.Bus BMS units. The included control cable connects directly to the BMS load disconnect output. Always ensure the relay is installed in a well-ventilated area and that cable sizing is appropriate for the 230 A continuous rating. Note that typical de-rating factors apply for sustained high-current operation; refer to installation guidelines for optimal performance.

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.

Pretty good, take your time and install it well
Size: side table leg
Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced

Heavy duty legs for table.
Size: side table leg
Perfect legs for a table I am having made. I have an cottonwood slice. It's heavy and needed something substantial. These are perfect.

Robust pipe & fittings with a beautiful, smooth black finish
Size: side table leg
This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.
