Key Functions & Specifications
Intelligent Combiner Protection
The Cyrix-Li-ct disengages immediately when its control output becomes free floating, signalling cell over-voltage or cell over-temperature, or when battery voltage drops below 13.2V.
Start Assist Function
To use start assist on the Victron Cyrix-Li-ct, send a short negative pulse to the start-assist terminal — the relay closes for 30 seconds, letting you jump start from your lithium house battery. If start assist seems not to work, verify the pulse duration and control wiring, since the relay only holds closed for the 30-second window.
Built-In Transient Suppression
A built-in transient voltage suppressor limits the voltage spike that can occur when the Cyrix suddenly disengages due to cell over-voltage or over-temperature, protecting your system electronics.
Comparison & Selection
Compared to simple VSR combiners, the Cyrix-Li-ct is purpose-built for LiFePO4 systems with BMS-controlled disengage. Alternatives like manual isolators lack automatic over-voltage and over-temperature protection, making this the smarter affordable value at $50.00.
