The Cyrix-ct automatically combines batteries (e.g., starter and house) when charging voltage is present and disconnects when not, ensuring efficient charging and preventing back-discharge. Suitable for 12V or 24V systems. Get it at a special price of $52.63 (regular $107.50).
Intelligent monitoring prevents unwanted switching. Overheating protection disengages on excessive temperature. Manual parallel function (start assist) via button or switch. No voltage loss, making it a great replacement for diode isolators.
Voltage: 12/24V. Continuous current: 120A. Smart trend-based switching. 5-year warranty.
For most alternators up to 120A, yes. For higher output, consider the 230A model. Check your alternator rating and wire size.

For alternators up to 120A, choose this model. For larger systems, consider the 230A version (also available). Both ensure efficient charging without voltage drop.
You can buy it here at a discount: $52.63 instead of the regular $107.50. That's 51% off. Use code SAVE15 at checkout for an extra 15% discount.
If your alternator's maximum output is up to 120A, yes. For higher output, you may need the 230A model. Also consider wire gauge and fusing.
Mount the unit near the batteries, connect the starter battery positive to the input, and the house battery positive to the output. Connect the ground. Follow the manual for detailed wiring. Ensure proper fusing on each battery line.
The main difference is the continuous current rating: 120A vs 230A. The 230A is suitable for larger charging sources. The switching logic is the same.
The dimensions are approximately 1.8 x 2.6 x 1.2 inches (H x W x D). Weight is about 0.4 lb.
This battery combiner does exactly what it's supposed to. I installed it to charge my starter battery from the house battery when the engine is running. Works flawlessly.
It's a solid product, but the instructions could be clearer. Once installed, it's been reliable.
Works great.
I have a dual battery system in my truck. This combiner automatically connects them when charging and isolates when the engine is off. No more manual switches. Best investment.
It's a quality piece, but I expected a lower price. Still, it does the job well.
I used to have a manual switch to combine batteries. This is automatic and smart. It detects voltage and combines only when charging. I feel safer knowing it won't drain my starter battery.
The install requires some electrical knowledge. If you're not comfortable with wiring, get a pro.
Victron is known for quality, and this is no exception. Heavy-duty terminals, clear wiring diagram. Works like a charm.
For $52, it's a steal. It's saved me from having to buy a new starter battery. Highly recommend.
We have a small sailboat with two batteries. This combiner connects them when the engine alternator is running, so both get charged. It's also great for emergency starting assist. Love it.
The red indicator light is quite bright at night. I had to cover it. Otherwise, it works fine.
