The Victron Energy Cyrix-Li-ct 12/24V-120A Battery Combiner is designed to connect a lead-acid starter battery with a LiFePO4 battery in compatible 12V or 24V systems. Rated for 120A continuous current, it works with the VE.Bus BMS Charge Disconnect output to prevent connection when lithium battery charging must be stopped.
The relay connects when BMS and voltage conditions are safe and disconnects immediately for cell overvoltage, overtemperature or low battery voltage. Start Assist can temporarily close the relay for 30 seconds, while IP54 protection suits vehicle, marine and mobile battery installations
