Cyrix-ct 12/24V-120A Battery combiner kit

Item number: 17750

Kit for adding a 2nd or 3rd battery system.
This makes it very easy to install an extra battery.
A piece of cake with this quality set from Victron.
Detailed installation manual included.

The Cyrix battery connector automatically switches 2 batteries parallel if one of the batteries exceeds a preset voltage level (charging). If the voltage falls below the maintenance voltage value, it disconnects the batteries again.
The battery connector replaces a disconnect relay and does not require a D-Plus signal. Since working without isolation diodes, virtually no voltage loss occurs.

Here the battery connector is supplied in a set with cables and installation material.

Kit for adding a 2nd or 3rd battery system in your car, boat, RV or whatever you wish.
It utilizes the simplest and most advanced technology to keep all your batteries charged using the engine's electrical system, but isolates the starting batterie when charging ceases so you never get stranded.

The Cyrix-i 12/24 is a bidirectional voltage sensitive relay.
It will therefore also engage if for example the accessory battery is being charged by a battery charger or solar.

Intelligent battery moitoring prevents cycling.
The software of the cyrix does more than simply connect and disconnect based on battery voltage and with a fixed time delay.THE cyrix looks at the general trend ( voltage increasing or decreasing ) and reverses a previous action only if the trend has revered during  a certain period of time. The time delay depends on the voltage deviation from the trend.

Easy to install.
There is no need to cut into any factory wiring that may void the manafacturer's warranty of your boat or vehicle.

Cables and lugs included:
- 6mtr RED 102
- 0,5mtr black 10mm2
- 0,2mtr black 1,5mm2
-
2 pcs M8 cable lug
- 4 pcs M6 cable lug
- 4 pcs cable tie

Intelligent battery monitoring to prevent unwanted switching
Some battery combiners (also called voltage controlled relay, or split charge relay) will disconnect a battery in case of a short but high amperage load. A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected.
The software of the Cyrix-ct 12/24 does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 12/24 looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time. The time delay depends on the voltage deviation from the trend.

Long bolts to allow connection of more than one power cable
Cyrix 12/24-120: 13 mm (M6) Cyrix 12/24-230: 16 mm (M8)
Protection against overheating (due to a long duration overload e.g.)
The Cyrix will disengage in case of excessive contact temperature, and reengage again after it has cooled down.
The Cyrix-ct 12/24 automatically detects system voltage.
No voltage loss

Cyrix battery combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
Prioritising the starter battery
In a typical setup the alternator is directly connected to the starter battery. The accessory battery, and possibly also a bow thruster and other batteries are each connected to the starter battery with Cyrix battery combiners. When a Cyrix senses that the starter battery has reached the connect voltage it will engage, to allow for parallel charging of the other batteries.
Bidirectional voltage sensing and power supply from both batteries
The Cyrix senses the voltage of both connected batteries. It will therefore also engage if for example the accessory battery is being charged by a battery charger.
The Cyrix-ct 12/24 has a dual power supply. It will therefore also close if the voltage on one battery is too low to operate the Cyrix.
In order to prevent unexpected operation during installation or when one battery has been disconnected, the Cyrix-ct 12/24 will not close if the voltage on one of the two battery connections is lower than 2 V (12 V battery) or 4 V (24 V battery).

Parallel connection in case of emergency (Start Assist)
The Cyrix can also be engaged with a push button (Cyrix remains engaged during 30 seconds) or a switch to connect batteries in parallel manually.
This is especially useful in case of emergency when the starter battery is discharged or damaged.
