The Victron Energy Cyrix-ct 12/24V-120A intelligent battery combiner automatically connects batteries in parallel when charging is available and disconnects them when voltage falls, helping protect the starter battery. It supports 12V and 24V systems, carries 120A continuously and 180A for 5 seconds, with virtually no voltage loss.
Microprocessor-controlled trend detection helps prevent unwanted switching, while bidirectional voltage sensing allows charging from either battery side. Start Assist can parallel the batteries for 30 seconds in an emergency, and IP54 protection suits vehicle, marine and auxiliary battery installations.
