Cyrix-Li-ct 12/24V Intelligent Li-ion Battery Combiners

Cyrix i Battery Combiner 24 48V 400A

Price range: $75.65 through $162.35

-

The Victron Energy Cyrix-Li-ct is a microprocessor-controlled battery combiner that automatically connects lithium battery banks in parallel when charging is detected and disconnects them when voltage drops, helping protect batteries from excessive discharge. This intelligent operation ensures efficient charging while maintaining battery health and system reliability.

Designed as a superior alternative to traditional diode isolators, the Cyrix-Li-ct eliminates voltage loss, allowing your alternator or charger to deliver full charging voltage to your batteries. Its heavy-duty relay construction and precise voltage sensing make it ideal for vehicle, marine, and off-grid lithium battery systems requiring dependable automatic battery management.

Features

  • 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, signaling cell over voltage or cell over temperature, and/or
    • When battery voltage drops below 13.2V
  • Start assist function: a short negative 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.
