It acts as a critical second line of defence, automatically connecting or disconnecting a battery charger based on signals from the BMS to prevent cell overvoltage and over temperature conditions. This ensures your lithium battery bank remains within safe operating limits, extending service life and maintaining system reliability in demanding mobile, marine, and off-grid applications.\u003c\/p\u003e\n\u003cp\u003eUnlike generic voltage sensing relays, the Cyrix-Li-Charge responds directly to the VE.Bus BMS Charge Disconnect output, providing a coordinated protection strategy that generic relays cannot offer. This reduces the risk of cell damage from overcharging, a common failure point in lithium systems without proper BMS integration.\u003c\/p\u003e\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-Charge engages the charger connection with a 3-second delay when the BMS Charge Disconnect signal is high and it detects sufficient voltage on both the charger and battery terminals. It disengages immediately if the BMS signals a fault, such as cell overvoltage or over temperature, isolating the charger to prevent further stress on the cells. After a brief recovery, it attempts to reconnect automatically, with progressively longer delays if faults persist, preventing rapid cycling that could damage components.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e230 A continuous rating\u003c\/strong\u003e at 12 V or 24 V for high-current charging systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect VE.Bus BMS control\u003c\/strong\u003e for coordinated lithium battery protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmediate disengagement\u003c\/strong\u003e on cell overvoltage or over temperature signals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic reconnection\u003c\/strong\u003e with intelligent delay logic to avoid nuisance cycling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in transient voltage suppression\u003c\/strong\u003e protects against voltage spikes during disconnection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED status indicator\u003c\/strong\u003e for at-a-glance operational and fault monitoring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow current consumption\u003c\/strong\u003e (\u0026lt;4 mA when open) minimises parasitic drain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 rated\u003c\/strong\u003e enclosure resists dust and water splashes for harsh environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/8\"-16 (Approx.

The Cyrix-Li-Charge bridges this gap, delivering precise, automated protection that reduces the risk of thermal runaway and premature capacity loss. Its 230 A continuous rating supports large battery banks, while the low standby draw preserves battery state of charge during storage.\u003c\/p\u003e\n\u003cp\u003eFor installers and system integrators, the Cyrix-Li-Charge simplifies wiring and enhances safety by centralising charge control through the proven Victron ecosystem.
