Victron Cyrix-ct 120A Battery Combiner 12/24V | 4Boats

The Victron Cyrix-ct 120 A intelligent battery combiner automatically connects and disconnects two 12/24 V battery banks to share charging while protecting each battery. It enables seamless charging distribution from alternators and chargers without voltage loss between batteries.

• Automatic operation: connects/disconnects two independent battery banks by monitoring voltage trends to share alternator and leisure charging while preventing deep discharge.
• Specifications: Continuous current: 120 A; Cranking current (5 s): 180 A; Standby consumption: <4 mA.
• Electrical: Rated voltage: 12 V / 24 V. Terminal size: 8 mm (M8).
• Mechanical: Dimensions: 46 x 46 x 80 mm (1.81 x 1.81 x 3.15 in). Weight: 110 g (3.88 oz).
• Features: Bi-directional power flow with negligible voltage loss between batteries; automatic 12/24 V detection; Start Assist manual override for emergency starting.
• Installation notes: To prevent battery damage or deep discharge, both battery banks in the system must have the same rated voltage. Installation requires appropriate fusing on the positive feeds and a common negative. Note that some smart alternators (for example Euro 6+ engines) may be incompatible with voltage-sensing relays.
