The Victron Energy Cyrix-ct 12/24V-120A Battery Combiner Kit Retail adds a second or third battery to a car, boat, RV or other vehicle while using the engine’s electrical system to keep batteries charged. Its microprocessor-controlled relay automatically parallels batteries when charging voltage rises and isolates the starter battery when charging stops, helping prevent unwanted discharge.
The kit uses a 120A Cyrix-ct intelligent battery combiner with 12/24V auto-ranging, virtually no voltage loss, Start Assist and IP54 protection. Supplied installation components make it a practical solution for reliable dual- or multi-battery vehicle systems.
