Victron CYR010230010 Cyrix-ct Intelligent Battery Combiner 12/24V / 230A
The Victron Cyrix-ct 12/24V / 230A Battery Combiner is a microprocessor-controlled heavy-duty relay designed to automatically manage the connection between batteries based on system voltage. When one battery reaches a preset voltage — indicating it is being charged — the Cyrix-ct closes and parallels the batteries. When voltage falls below float level — indicating discharge — it opens again to protect the charging source and batteries. This behavior makes the Cyrix-ct an excellent replacement for diode isolators, with the key advantage of virtually no voltage loss, so alternators and chargers can operate at full output without increased voltage settings.
Automatic Battery Combining
The Cyrix-ct continuously monitors voltage and automatically connects or disconnects batteries as needed. It intelligently links batteries during charging and separates them during discharge, preventing unwanted battery drain while maximizing charge delivery.
Wide Voltage Compatibility
Designed for both 12 V and 24 V systems, the Cyrix-ct 12/24V automatically detects system voltage and adapts accordingly. This makes it versatile for a range of mobile and off-grid dual-battery setups.
High Current Capacity
With a continuous current rating up to 230 A, this combiner can handle heavy loads typical in RVs, boats, vans, and other dual-battery systems, providing dependable performance even under demanding conditions.

Testimonials
Highly recommend HTV
My wife and I just got a high-top roof installed on our 2000 Ford E250, and it completely changed the van. Micah and Lindsay were very nice, awesome to work with, super knowledgeable, and full of helpful tips for our future build.
Top notch, quality work!
Micah and Lindsay were amazing to work with. I had so many questions that Micah patiently answered. He even made recommendations for parts that had nothing to do with the top just because he wants people to have a good experience with their vans.
I couldn't be happier
Micah and Lindsay were absolutely incredible to work with. You can tell right away they take pride in what they do and truly care about their customers. They are some of the most genuine and authentic people I've ever met.
High Top Vans, do I recommend HTV's, absolutely!
Micah is meticulous, I realized when I saw his tool chest, ridiculous organization. They installed and wired my solar panels, roof penetration, prewire Starlink, solar breaker, MMPT solar controller, DC to DC charging, shore power, wire batteries, Lynx distributors, Cerbo GX, air conditioner, MaxAir fan, ran power to my 12V and 120V electrical panels.
High Top Vans does great work and I highly recommend them.
I called on Monday they had a opening in there schedule and the top was installed on Thursday. Micah and Lindsay are very knowledgeable and gave us much insight on continuing our build.
Highly recommend HTV I love my new top
Micah and Lindsay were both amazing and super helpful with any questions I had. The top was installed in 6h with a new max van too!!! and only 1 week after my initial contact still can't believe it...
We love our High Top from HTV.
Micah and Lindsay were both great to work with and super helpful with any questions we had. We spent a relaxing day in Camas Wa while they worked their magic and we couldn’t be happier. We 100% recommend HTV for your van build needs.
