The Victron Energy Cyrix-ct 12/24V-120A Intelligent Battery Combiner is a microprocessor-controlled heavy-duty relay for 12V and 24V battery systems. It automatically connects batteries in parallel when charging voltage is detected and disconnects them as voltage falls, helping protect the starter battery while allowing efficient charging from either battery side.
With 120A continuous current, intelligent voltage-trend detection, bidirectional sensing, Start Assist, virtually no voltage loss and IP54 protection, the Cyrix-ct is well suited to vehicle, marine and auxiliary battery installations where reliable automatic battery combining is required.
