Victron Cyrix-ct 12/24V-230A: Intelligent Battery Combiner for Dual-Battery Systems

Advanced Voltage Sensing Relay for Reliable Parallel Charging

The Victron Cyrix-ct 12/24V-230A is a microprocessor-controlled voltage sensitive relay (VSR) designed to intelligently manage dual-battery systems in vehicles, boats, and off-grid installations. Unlike conventional split charge relays that rely on simple voltage thresholds and fixed time delays, the Cyrix-ct uses intelligent trend detection to prevent unwanted switching caused by momentary voltage dips or spikes. This ensures your auxiliary battery bank charges reliably without premature disconnection, even when powering high-demand loads.

Engineered for 12V and 24V auto-ranging systems, this 230A continuous battery combiner is an ideal solution for caravan battery charging, marine dual-battery setups, 4x4 auxiliary power, and commercial vehicle electrical systems. Its bidirectional voltage sensing and dual power supply allow it to engage from either battery side, making it a versatile component in any DC charging architecture.

Intelligent Trend Detection: Smarter Than a Standard VSR

Traditional battery combiners often disconnect under short, high-amperage loads or fail to connect a deeply discharged battery bank because the voltage immediately drops below the disengage threshold. The Cyrix-ct overcomes these limitations by analysing the voltage trend over time. It only reverses a connection decision if the trend has genuinely reversed, with a time delay proportional to the voltage deviation. This prevents nuisance switching and ensures stable, continuous charging.

Key Features

  • 230A continuous current rating with 500A cranking capacity for 5 seconds, supporting large battery banks and high inrush loads
  • 12/24V auto-ranging automatically detects system voltage, simplifying installation across mixed fleets
  • Bidirectional voltage sensing and dual power supply allow engagement from either battery, ideal for alternator or shore charger input
  • Start Assist function enables manual parallel connection for 30 seconds via push button or switch, providing emergency cranking power from the auxiliary battery
  • Over-temperature protection disengages the relay if contact temperature exceeds safe limits, automatically reconnecting after cooling
  • LED status indicator provides clear visual feedback: engaged, disengaged, connecting, disconnecting, and alarm states
  • Virtually zero voltage drop across the contacts, eliminating the need to increase alternator or charger output voltage as required with diode isolators
  • Prioritises starter battery by only engaging when the starter battery reaches the connect voltage, ensuring reliable engine starting
  • 16 mm (M8) long bolts allow secure connection of multiple heavy-duty cable lugs
  • IP54 protection rated for dust and water spray, suitable for engine bays and exposed installations
  • Low current consumption: less than 4 mA when open, 320 mA (12V) or 180 mA (24V) when closed

Built for Demanding Environments

The Cyrix-ct operates reliably in temperatures from -40 to +60 °C, making it suitable for Australian outback conditions, marine engine rooms, and cold-climate expeditions. Its compact dimensions (65 x 100 x 50 mm) and lightweight design (0.27 kg) allow flexible mounting in tight spaces. The included 1-metre control cable simplifies integration with existing wiring, while the robust M8 stud terminals accommodate heavy-gauge cables for minimal resistance.

Applications

  • Caravans and motorhomes: automatically charge house batteries from the alternator while driving
  • 4x4 and off-road vehicles: maintain auxiliary power for winches, fridges, and lighting
  • Marine vessels: combine starter and service battery banks for efficient charging underway or at dock
  • Commercial trucks and buses: manage multiple battery banks for lift gates, communications, and auxiliary equipment
  • Off-grid solar systems: integrate with battery chargers to parallel charge multiple battery strings

Why Choose the Cyrix-ct Over Diode Isolators?

Diode isolators introduce a voltage drop of 0.6-0.7V, requiring higher alternator output and reducing charging efficiency. The Cyrix-ct uses a mechanical relay with negligible voltage loss, ensuring your batteries receive the full charging voltage. This leads to faster, more complete charging and longer battery life, especially critical for AGM and lithium batteries that require precise voltage regulation.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book. Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray. I wish it had been proofread - there are a lot of typos, but nothing too distracting.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more. I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things. It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic. I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together. I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray. Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat
