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.

Looooves her crazy new ball
Color: Orange, Color: Orange
Our 90lb mastiff/boxer mix Indie is very playful, curious and energetic. She needs toys that engage her and keep her busy. This ball does the job! We’ve had it for less than a week. Here’s what I love and what could be better: PROS: • She dog loves it. She whines for it. She gets absurdly excited when I get it out. She’s a bit of an anxious dog, but had zero problems with it inexplicably coming to life. • It lasts a while on a single charge, so it keeps her busy for a good long time. The longest we’ve used it at a stretch is an hour. • It’s pretty durable. She’s a super chewer (destroyed every “non-destructible” toy we’ve purchased for her), but the actual ball is hard plastic. She gnaws on it and it gets scratches, for sure. But she’s not going to chew it to pieces. • On carpet, it’s reasonably quiet. • It comes with a replaceable silicone button. • It’s easy to charge…just pull off the silicone button and the charging port is inside. • The silicone button is flush with the ball’s hard plastic surface, so there’s no way for her to pull the silicone button out and swallow it or get to the charging port. CONS: • Cover is worthless if your dog is a chewer. It goes on like an envelope with a Velcro closure. We took it off immediately. • Without the cover, it’s very noisy on hardwood floors. To us, it’s worth it. (Though, I work from home, so I might feel differently after the holiday vacation.) • She’s an XL dog, so she can fit the whole ball in her mouth easily and accidentally chomp down on the button and turn the ball off. Not a big deal, just something to know if you’ve got a Lab or larger dog. • With extended playtime, the two halves can come unscrewed, especially with a large dog who uses their paws/jaws on it a lot. Thankfully, it makes a loud buzzing noise when this happens, so we know we need to take it from her and screw it back together. Is this a potential danger? With the rechargeable battery inside, I’d say yes. But we also don’t let her play with this toy without supervision. So keep that in mind. Bottom line: It has its drawbacks, but it keeps her entertained and seems like it should last her at least 6 months with supervised play. Which is honestly REALLY good when we’re talking about Indie, Destroyer of Toys. I’d buy it again.

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it. First the pros... - I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly. - This interactive PetDroid ball, however, keeps them busy for a long time. - In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time. - Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time. Now, the cons... - After several days of play, the exterior looks chewed up quite a bit. That's no problem though. - Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny. - Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device. - It appears the 2 cups somehow come off track and get realigned from the inside. - At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play. - Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it. Proposed Solution: - Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track. - This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it. In my view, this should be a relatively simple fix and significantly improve the durability of this product. Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.

Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars. Promising Features, Lackluster Results The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest. Durability I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place. Motion Activation The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it. Lack of Engagement The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest. Final Thoughts Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it. Pros: Durable construction Motion-activated as advertised Cons: Did not engage my dog Motion activation wasn’t intriguing enough Might be more suitable for specific dog types or personalities If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.
