The Victron Energy Cyrix-Li-ct 12/24V-230A Intelligent Li-Ion Battery Combiner connects a lead-acid starter battery with a LiFePO4 battery in compatible 12V or 24V systems. Rated for 230A continuous current, it works with the VE.Bus BMS Charge Disconnect output and voltage conditions to control when the batteries are paralleled.
It disconnects immediately if the BMS signals cell overvoltage or overtemperature, or when battery voltage falls too low. Start Assist can close the relay for 30 seconds, while IP54 protection, LED status indication and the included 1 m control cable support reliable vehicle, marine and mobile-power installations.
