Cyrix-i Victron battery coupler kit

Kit for adding a 2nd or 3rd battery system to your car, boat, motorhome or whatever you want. It uses the simplest, most advanced technology to keep all your batteries charged using the engine's electrical system, but isolates the starter battery during charging stops, so you're never left flat.

The Cyrix-i 12 / 24-120 is a voltage-sensitive bidirectional relay. It therefore also engages if, for example, the accessory battery is charged by a battery charger.

Intelligent battery monitoring prevents cycling.

The Cyrix software does more than simply connect and disconnect according to battery voltage and with a fixed delay. The Cyrix examines the general trend (rising or falling voltage) and reverses a previous action only if the trend has reversed within a certain time period. The time delay depends on the voltage deviation from the trend.

Parallel emergency function.

An emergency start push-button can be connected to the start connection (85) if required. The relay will switch on for 30 seconds after the "start aid" function has been momentarily connected to the battery plus. Alternatively, a parallel connection switch can be used to engage the relay as long as the switch remains closed.

Easy to install.

There's no need to cut into any factory wiring that may void your boat or vehicle manufacturer's warranty.
