This 120A Victron Cyrix-ct intelligent battery combiner automatically connects and disconnects two independent battery banks based on voltage trends, optimising the sharing of power between batteries. This is perfect for vehicle battery systems where alternator charging can be shared with the leisure battery, and leisure charging (such as solar power or mains hook-up) can be shared with the engine starter battery.
Key Features
Intelligent monitoring and tracking of both battery systems, shares charging without over-discharging either battery
Full protection against over-discharge, overcurrent, over-temperature or over-voltage
Automatic 12V/24V system voltage detection
No loss of voltage between batteries
Bi-directional power flow shares charging in both directions
Start Assist manual override, allows leisure battery to assist with engine start-up in case of starter battery damage or deep discharge
 
Note: both battery banks in the system must have the same rated voltage. Smart alternators in Euro 6 or later engines may not be compatible with Voltage Sensing Relay technology such as this battery combiner.
