This intelligent, microprocessor-controlled device seamlessly connects your lead-acid starter and LiFePO4 house batteries only when charging is active, preventing starter battery discharge. It works with the VE.Bus BMS for superior LFP battery protection against over-charge and over-temperature. Enjoy zero voltage loss for efficient charging and an emergency start-assist function. Essential for reliable power on board. VICTRON ENERGY Cyrix-Li-Charge 28/48V 120A RelayCategory: Boats and equipmentSubcategory: Anchoring and mooringEnsure the ultimate safety, reliability, and performance of your vessel´s dual-battery system with the VICTRON ENERGY Cyrix-Li-Charge 28/48V 120A relay. This intelligent, microprocessor-controlled device is the cornerstone of modern marine power management, specifically engineered to manage the parallel connection between a traditional lead-acid starter battery and a high-performance LiFePO4 (LFP) house battery bank. By creating a seamless and protected charging environment, it safeguards your critical power systems, allowing you to focus on your journey with complete peace of mind.The Cyrix-Li-Charge excels by providing intelligent control over when your batteries are connected. It engages automatically once the starter battery reaches a preset voltage, indicating that a charging source like an alternator or battery charger is active. This allows the charge current to flow to and top up your expensive lithium battery bank. Crucially, it will immediately disengage when the charging stops, preventing any accidental discharge of the starter battery and ensuring you always have the power needed to start your engines. This functionality eliminates the significant voltage loss associated with traditional diode isolators, maximizing your charging efficiency and reducing engine run time.Designed to integrate flawlessly into a Victron ecosystem, this relay is controlled by the VE.Bus BMS (Battery Management System). This vital connection provides an unparalleled layer of protection for your lithium battery investment. The Cyrix-Li-Charge will not engage if the BMS issues a charge-disconnect signal, which can occur due to potential cell over-voltage or over-temperature. This prevents damage to the LFP battery, extending its service life and guaranteeing safe operation under all conditions. It also features a unique temperature protection system, where the relay will disengage in the event of overheating, adding another layer of robust safety.In an emergency, the Cyrix-Li-Charge offers a start-assist function. A momentary push of a button or switch can engage the relay for 30 seconds, allowing you to parallel the lithium main battery with the starter battery for an emergency engine start.Key Benefits:* Intelligent Battery Paralleling: Safely connects a lead-acid starter battery and a LiFePO4 battery only during active charging, preventing unwanted discharge and ensuring starter battery integrity.* Superior Lithium Battery Protection: Works in conjunction with a VE.Bus BMS to prevent over-charge and over-temperature conditions, safeguarding your high-value LFP battery bank.* Zero Voltage Loss: Functions as a heavy-duty relay, eliminating the voltage drop inherent in diode battery isolators for more efficient and faster charging.* Prioritized Starter Battery Charging: Intelligently prioritizes the engine starter battery, ensuring it is always ready for operation before channeling charge to the house bank.* Emergency Start Assist: Provides a manual override to parallel the batteries for a short duration, enabling you to start the engine from the house battery in an emergency.Main Features:* Microprocessor-controlled for precise and reliable switching.* Direct control input from the Victron VE.Bus BMS.* Bi-directional voltage sensing with starter battery priority.* No voltage loss for maximum charging efficiency.* Integrated over-temperature protection.* Emergency start-assist capability.Technical Specifications:* Product Type: Relays* Model: Cyrix-Li-Charge 28/48V 120A* System Voltage: Automatic 12/24V detection (operates within systems designated up to 48V)* Continuous Current Rating: 120A* Cranking Rating (5 seconds): 180A* Control Input: Connects to the Charge Disconnect output of a VE.Bus BMS* Protection Class: IP54. tradeinn Waveinn
