Victron Cyrix CT Intelligent Leisure Battery Combiner


The Victron Cyrix CT Leisure Battery Combiner is a voltage sensing split charge relay and an ideal way to keep your campervan, motorhome leisure and starter battery charged.

Intelligent Battery Combiner and Monitoring

The Victron Cyrix CT Battery Combiner can also be named a voltage-controlled relay or even a split charge relay is designed to disconnect from a battery if there is a short but high amperage load. Doing much more than just connecting and disconnecting a battery based on the voltage to the battery the Cyrix CT uses software that also looks at the general trend of the leisure battery's voltage.

How Does It Work

The Victron Cyrix CT Battery Combiner senses the voltage of both leisure and starter batteries in the Campervan, and prioritises the starter battery, but when the cut in voltage is reached, the Cyrix CT then engages the second and or leisure battery in the Motorhome or Campervan.

This split charge voltage sensing relay features voltage trending software to overcome short-term fluctuations in voltage levels between your campervan motorhome leisure batteries, and prevent unwanted disconnection.
