{"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.

Over time, one battery is repeatedly overcharged while the other is undercharged, accelerating degradation and shortening the life of the bank. The Battery Balancer addresses this directly by monitoring the mid-point voltage and diverting current from the higher-voltage battery to the lower-voltage one whenever the bank is being charged above 27.3V.\u003c\/p\u003e\n\n\u003cp\u003eThe balancing process is passive in the sense that it requires no manual intervention. Once wired in, the unit monitors continuously and activates only when needed. The 1A balancing current is deliberately modest: it is enough to correct the gradual drift that occurs in real-world installations without generating excessive heat or requiring additional thermal management. For larger battery banks made up of multiple series-parallel strings, two or more Battery Balancers can be deployed together to maintain balance across the full bank.\u003c\/p\u003e\n\n\u003cp\u003eThis product is specific to 24V lead-acid systems.

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.

When the alternator or an external charger raises the voltage on the starter battery side above the connection threshold, the relay closes and allows charge current to flow into the lithium bank as well. When charging stops and voltage drops, the relay opens again, keeping the two banks isolated. This prevents the lithium battery from back-feeding the starter battery and ensures the engine always has a reliable start.\u003c\/p\u003e\n\n\u003cp\u003eThe critical difference between this unit and a standard Cyrix-ct relay is its direct integration with a lithium BMS. The BMS charge-disconnect output connects directly to the Cyrix-Li-charge. If the BMS detects a cell overvoltage or temperature condition and signals a charge stop, the relay opens within milliseconds regardless of the voltage present on the bus. This is a hard requirement for safe lithium operation that a conventional voltage-sensing relay cannot provide. Installers working with lithium battery systems should treat this BMS interface as a mandatory part of the installation, not an optional feature.\u003c\/p\u003e\n\n\u003cp\u003eAt 230A, the relay handles the full output of most marine and vehicle alternators without derating.
