Victron Cyrix-ct 12/24V-120A intelligent battery combiner

The Cyrix Battery Combiner is a microprocessor-controlled heavy-duty relay that automatically connects batteries in parallel when charging voltage is detected and disconnects them when voltage drops below float level. It replaces diode isolators with virtually no voltage loss, ensuring efficient charging without needing to increase alternator or charger output voltage.

Features:

• Intelligent voltage trend monitoring to prevent false switching
• Connects/disconnects batteries only on sustained voltage changes
• Long bolts for multiple cable connections (M6 or M8)
• Overheat protection with automatic disengage and reengage
• LED status indicators (on 12/24-230 model)
• Auto-detects 12V or 24V systems
• Virtually no voltage loss, better than diode isolators
• Prioritizes starter battery charging before accessory batteries
• Bidirectional voltage sensing from both batteries
• Dual power supply ensures reliable operation at low voltage
• Manual emergency parallel connection (Start Assist) function
