The Victron Cyrix-Li-Charge 230A is a microprocessor-controlled heavy-duty relay designed for LiFePO4 systems. Unlike standard combiners, this relay integrates seamlessly with the VE.Bus BMS. It protects the battery by instantly disconnecting chargers in the event of imminent cell overvoltage or temperature extremes. Due to its negligible resistance, voltage drop is practically zero, eliminating the need to boost charger output.
Key Features:
Smart Control: Connects the charger with a 3-second delay once the BMS permits and charging voltage (>13.0V) is detected.
Superior Protection: Disconnects immediately if the control input becomes 'free floating' due to cell alarms.
LED Diagnostics: Features an integrated LED providing real-time status updates on operation and alarms.
Zero Voltage Loss: An excellent alternative to diode-based battery isolators.
