The Victron Energy Cyrix-ct 12/24V-230A Intelligent Battery Combiner automatically connects two batteries in parallel when charging is detected and separates them when voltage falls, helping protect the starter battery. It supports 12V and 24V systems, carries 230A continuously and handles 500A cranking current for 5 seconds.
Its microprocessor-controlled trend detection reduces 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 the IP54 enclosure suits vehicle, marine and auxiliary battery installations.
