VICTRON ENERGY Cyrix-Li-CT 12/24V-120A Intelligent Battery Combiner Relay
Ensure ultimate reliability and optimal performance for your vessel´s dual battery system with the VICTRON ENERGY Cyrix-Li-CT 12/24V-120A Combiner Relay. Specifically engineered for marine applications incorporating modern lithium (LiFePO4) battery banks, this intelligent relay is the cornerstone of a safe and efficient onboard power management system. It eliminates the risk of a dead starter battery while ensuring your auxiliary lithium bank receives a proper and controlled charge, protecting your valuable investment.
The battery combiner Cyrix-Li-Ct of 120 amps is a relay heavy duty microprocessor controlled automatically connects the batteries in parallel when a battery has reached a preset voltage and detaches when the voltage drops below the float level when used as part of a control system for a bank of lithium ions, this combiner intelligent battery Cyrix used to disconnect an auxiliary battery when the main battery of lithium ion is filling.
It can be controlled remotely by the system battery management.
It works with a time delay to prevent nuisance activities.
Unlike traditional diode battery isolators, the Cyrix-Li-CT boasts virtually zero voltage loss, meaning your alternators and battery chargers operate at maximum efficiency without needing voltage compensation. Its intelligent, microprocessor-driven logic automatically detects your system´s voltage (12V or 24V) and manages the connection between the starter and auxiliary battery with unparalleled precision. It prioritizes the starter battery, ensuring it´s always ready to crank the engine, before allowing charge to flow to the auxiliary bank.
Key Benefits for the Modern Mariner:
* Optimized for Lithium Systems: Designed to integrate seamlessly with a Victron VE.Bus BMS or any compatible Battery Management System, providing essential control for charging LiFePO4 batteries safely.
* Intelligent Charging Priority: The system always ensures the conventional lead-acid starter battery is fully charged before paralleling the connection to charge the lithium house battery bank.
* Superior Efficiency with No Voltage Loss: Avoids the 0.7-volt drop common with diode isolators, resulting in faster, more complete charging cycles and no wasted energy.
* Emergency Start Assist: In an emergency, a push-button or manual switch can parallel the batteries for 30 seconds, allowing you to use the power of the auxiliary bank to start the engine.
* Bidirectional Voltage Sensing: The Cyrix-Li-CT doesn´t just monitor the starter battery. It also senses the voltage of the auxiliary battery. This means if the auxiliary bank is being charged by a solar panel or shore power charger, the Cyrix will engage to top off the starter battery as well.
* Robust and Reliable: Built for the demanding marine environment, its heavy-duty construction and smart, time-delayed switching prevent unnecessary cycling caused by transient voltage drops.
