Victron Energy Cyrix-Li-Charge 12/24V-120A – Intelligent Charger Relay for Lithium Systems (CYR010120430)
The Cyrix-Li-Charge 12/24V-120A is a smart relay specifically designed to manage the connection between a charger and a Victron LiFePO₄ battery system. Controlled by the VE.Bus BMS, this relay protects lithium batteries by disconnecting the charger during cell overvoltage or extreme temperature events. It supports up to 120A of continuous current and operates based on intelligent voltage and control signal sensing, ensuring efficient, safe charging in off-grid, mobile, and marine applications.
Main Features
- Compatible with Victron VE.Bus BMS and LiFePO₄ batteries
- Automatically engages charger connection based on control signal and voltage detection
- Rated for 120A continuous current at 12V or 24V
- Immediate disengagement in case of cell overvoltage or overtemperature
- Automatic 3-second delay for re-engagement after safe conditions return
- One-hour periodic disengagement to verify charger activity
- Low idle power consumption <4 mA
Charging Logic
Condition Behavior Control input HIGH and battery charger terminal >13.0V (or >26.0V) Connect after 3 seconds Battery terminal >2V Required for Cyrix to close Control input floating (due to BMS disconnect) Disconnect immediately Cell overvoltage resolved Reconnect after 3 seconds 1 hour after engagement Temporarily disconnect to verify charger is still operating
