{"title":"Victron Battery Isolators","description":"\u003cp\u003eVictron battery isolators and combiners allow a single alternator or charger to charge two or more separate battery banks without the banks discharging into each other. The Cyrix battery combiners use an intelligent voltage-sensing relay to connect and disconnect battery banks automatically, making them ideal for split-charge systems in motorhomes, boats, and professional vehicles. Argodiode isolators provide a simple, reliable alternative for applications where voltage drop can be accommodated.

In a conventional combiner, the relay closes whenever either battery reaches a set voltage. The Cyrix-Li-charge is configured so that the lithium service battery side is passive: the relay only closes when the starter battery voltage rises, indicating that charging is actively taking place. This prevents the lithium bank from back-feeding into the starter battery when the engine is off.\u003c\/p\u003e\n\n\u003cp\u003eThe critical feature for lithium installations is the BMS integration. Victron lithium batteries with a BMS can output a charge disconnect signal when the battery is full or when a cell imbalance is detected. The Cyrix-Li-charge responds to this signal by opening the relay immediately, isolating the lithium bank from the charging source. This makes it a necessary component in any dual-battery system where a Victron lithium battery is used alongside a lead-acid starter battery charged by an alternator.\u003c\/p\u003e\n\n\u003cp\u003eThe unit handles 12V and 24V systems without any configuration change, making it a practical stock item for installers working across different vehicle and vessel platforms.
