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.

Works great & smells good!
Scent: Sandalwood
I was concerned the facial wash would be too harsh but thankfully I was wrong. Every part of this kit compliments the other. My skin and beard feel noticeably softer, and I haven't had any acne breakouts. The scent is masculine but not too strong. This is now my new routine.

Smells amazing!!
Scent: Sandalwood
My husband loves this set. He has sensitive skin, and loves this product since it doesn’t cause any irritation, plus it smells amazing! The face wash seems to be helping with beard acne, while not drying out the hair like other washes do, and the oil moisturizes well creating a healthy shine. I would say this is well worth your money if you are looking for a full starter kit to try something new and well-rounded for your beard care.

Great product at great price...
Scent: Sandalwood
As someone who's had a beard off and on for the better part of a decade, I've gone through my fair share of beard products. For the most part they're all very similar. The washes for the most part clean and leave a very squeaky clean (almost dry) feeling out of the shower. Conditioners help a bit after a wash, but not anything to write home about, the only one I've tried that I really liked was Scotch Porter. Oils help in hydrating, some are excessively oily and just don't look very appealing. Balms will help tidy up the overall shape of the beard, some are not really strong enough and just end up being another layer of oil on the wiskers. Ok, now for this review... So I believe this to be the most natural and most effective line of products I've found to date. First off, the wash, oh my, the wash... I could really just stop right there. This is my favorite of the line. It leaves my beard so soft I find myself not wanting to ruin it with a conditioner. If you try just one of these product, the wash is a must. Next we have the detangler, this is pretty much a leave in conditioner. It softens out the beard even further and adds a slickness to the beard, it feels great. The oil in the set is probably unnecessary since the wash and detangler do such a great job, but in any case it is a quality oil. The reason I say this is because it doesn't really stay oily in the hair, you can feel that after initially applying, it does absorb into either the follicle or skin, whichever it's intended to. As I mentioned, there are some oils that just don't do that, it's just greasy all day long. The balm is probably my least favorite of the line, but only because it's not a very strong holding balm. It's kind of like I mentioned, another layer of oil. This one does also absorb so it's ok. I prefer a more tacky balm with more wax rather than oils. Also, the scent of this line is a subtle chocolatey vanilla kind of smell. It's a very pleasant scent that my wife also enjoyed initially. However after about a week or so of using the product, I no longer get so much as a whiff, which is fine, I find that to be common with many of these beard oils and such. So, overall a great set of products that leave my beard feeling soft and hydrated all day long, it also feels like quality, in the sense that it does absorb. It doesn't feel like you just applied baby oil all over your face. I cannot stress this point enough, there are some "name brand" beard care product that feel as such. That's why this product line really stands out to me. Five stars...
