Available in two voltage versions — 12\/24V (CYR010230430) and 24\/48V (CYR020230430) — both rated at 230A continuous, it provides automatic high-current charge switching without any voltage drop, making it suitable for large alternators, multi-stage chargers, and high-current charging sources in demanding lithium battery installations where the 120A model would be undersized.\u003c\/p\u003e\n\u003cp\u003eThe Cyrix-Li-Charge 230A works in combination with the VE.Bus BMS or SmallBMS. The Charge Disconnect output of the BMS — which is normally high and goes free floating in the event of cell overvoltage or overtemperature — is connected to the 1-metre control cable included with the combiner. When the BMS output is high (normal operation) and the charger output voltage is at or above the connect threshold (13.0V for 12V systems, 26.0V for 24V systems, 52.0V for 48V systems), the Cyrix-Li-Charge connects the charger to the battery after a 3-second delay. When the BMS Charge Disconnect output goes free floating — signalling a cell overvoltage or overtemperature fault — the Cyrix-Li-Charge disconnects the charger immediately, protecting the lithium battery bank.\u003c\/p\u003e\n\u003cp\u003eThe Cyrix-Li-Charge 230A addresses the need to control high-current charging sources that cannot be directly switched off by the VE.Bus BMS Charge Disconnect output — such as large alternators, industrial battery chargers, and high-current DC-DC converters that require a relay to break the charging circuit rather than a signal wire to disable them. A built-in transient voltage suppressor limits voltage spikes that may occur when the Cyrix-Li-Charge suddenly disconnects an active charging source, protecting both the Cyrix and connected equipment from transient damage.\u003c\/p\u003e\n\u003cp\u003eThe 230A model offers double the continuous current capacity of the 120A Cyrix-Li-Charge, with a breaking capacity of 80A at 48V — making it the correct choice for large parallel battery banks and high-current charging systems. A LED status indicator shows engaged, disengaged, connecting, disconnecting, and alarm states at a glance. The 1-metre control cable is included in the box.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003ch4\u003eVE.Bus BMS Controlled — Automatic Charge Protection\u003c\/h4\u003e\n\u003cp\u003eControlled directly by the Charge Disconnect output of the VE.Bus BMS or SmallBMS — connecting the charger when the BMS output is high (normal operation) and disconnecting it immediately when the BMS output goes free floating due to cell overvoltage or overtemperature, providing automatic second-line-of-defence protection for the lithium battery bank.\u003c\/p\u003e\n\u003ch4\u003eSwitches High-Current Charging Sources Not Directly Controllable by BMS\u003c\/h4\u003e\n\u003cp\u003eDesigned for large alternators, industrial battery chargers, and high-current DC-DC converters that cannot be disabled directly by the BMS signal wire — providing a 230A relay-based charge interruption solution that the BMS can control regardless of the charging source type or brand.\u003c\/p\u003e\n\u003ch4\u003eVoltage-Sensing Connection Logic — No Unnecessary Switching\u003c\/h4\u003e\n\u003cp\u003eThe Cyrix-Li-Charge 230A only connects the charger when it senses that the charger output voltage is at or above the connect threshold (13.0V \/ 26.0V \/ 52.0V) — preventing connection of a dead or off charger and avoiding unnecessary relay cycling. Connection occurs with a 3-second delay; disconnection on BMS fault is immediate.\u003c\/p\u003e\n\u003ch4\u003eAutomatic Reconnection After Cell Overvoltage Reset\u003c\/h4\u003e\n\u003cp\u003eIn the event of a cell overvoltage alarm, the BMS disconnects charging. Once the overvoltage condition resets after charging has stopped, the Cyrix-Li-Charge 230A automatically reconnects the charger after a 3-second delay — restoring charging without manual intervention once the fault is cleared.\u003c\/p\u003e\n\u003ch4\u003eHourly Reconnect Check\u003c\/h4\u003e\n\u003cp\u003eWhen the Cyrix-Li-Charge is engaged, it disconnects briefly every hour to verify that the charger is still active. If the charger output immediately returns to the connect threshold voltage, the Cyrix reconnects with a 3-second delay — preventing silent charger failures from going undetected over long charge periods.\u003c\/p\u003e\n\u003ch4\u003eLED Status Indicator\u003c\/h4\u003e\n\u003cp\u003eA multi-state LED provides clear at-a-glance operational status: solid on (engaged), 10-second flash (disengaged), 2-second flash (connecting), 2-second blink (disconnecting), and rapid 0.25-second blink for alarm conditions including overtemperature, overvoltage, and critically low battery voltage.\u003c\/p\u003e\n\u003ch4\u003eBuilt-In Transient Voltage Suppressor\u003c\/h4\u003e\n\u003cp\u003eA built-in transient voltage suppressor limits the voltage spike that occurs when the Cyrix-Li-Charge 230A suddenly disconnects an active charging source — protecting both the combiner and connected equipment from transient damage during emergency disconnection events.\u003c\/p\u003e\n\u003ch4\u003e1-Metre Control Cable Included\u003c\/h4\u003e\n\u003cp\u003eA 1-metre control cable is included in the box, connecting the VE.Bus BMS or SmallBMS Charge Disconnect output to the Cyrix-Li-Charge 230A control input — providing a ready-to-install solution without requiring separate cable procurement for the BMS interface.\u003c\/p\u003e\n\u003ch4\u003eAvailable in 12\/24V and 24\/48V Versions\u003c\/h4\u003e\n\u003cp\u003eAvailable in a 12\/24V version (CYR010230430) for 12V and 24V lithium battery systems, and a 24\/48V version (CYR020230430) for 24V and 48V systems — both rated at 230A continuous (80A breaking capacity at 48V) and identical in physical dimensions, IP rating, and included accessories.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Hy0gbc6Eyu8\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"product-spec-table\" style=\"width: 100.036%;
