Victron Energy Cyrix-Li-ct 12/24V 120A Intelligent Li-ion Battery Combiner – CYR010120412

The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct.

The Cyrix-Li-ct will parallel connect a lead acid starter battery and a LiFePO4 battery:

• if the Charge Disconnect output of the VE.Bus BMS is high, and
• if it senses 13,4V (resp. 26,8V) or more on one of its power terminals

The Cyrix will disengage immediately:

• when its control output becomes free floating, signalling cell over voltage or cell over temperature, and/or
• when battery voltage drops below 13,2V. Start assist function: a short positive pulse will close the relay during 30 seconds

A built-in transient voltage suppressor will limit the voltage spike that may occur when the Cyrix suddenly disengages due to cell overvoltage or over temperature.
