The Cyrix-ct 12/24V-120A is a Victron battery combiner kit with a continuous current rating of 120 A. It works on 12V or 24V systems, and it separates the starting battery from the others once charging stops. It is rated for 180 A of cranking current for 5 seconds, and start assist keeps it engaged for 30 seconds. The case is IP54 and it draws 4 mA when open. Cables and lugs are included.
Our take
A 180 A cranking rating for 5 seconds against 120 A continuous, plus a 30 second start assist hold, tells you how this combiner is built to behave around engine starts. It isolates the starting battery when charging stops, and it draws 4 mA while open.
From our buying guide
NMMA says not to mix battery chemistries or types in the same bank, and the makers add their own limits.
Check before you buy:
- Each maker sets its own alternator rules. Battle Born calls a DC-to-DC charger a simple and safe way to use alternator charging.
- Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
- Ignition protection on a charger or switch is the maker's statement, so read what it says and which standard it names.
