Victron Battery Isolators and Combiners

Switches Cables Connectors Wiring

Argo diode battery isolators allow simultaneous charging of two or more batteries from one alternator.

The Cyrix automatically connects or disconnects battery systems without voltage loss.

The Battery Protect diconnects the battery from non essential loads before it is completely discharged or before it has insufficient power left to crank the engine.

Similarly to diode battery isolators, FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together.

In contrast to diode battery isolators, FET isolators have virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.

Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together.

Discharging the accessory battery for example will not result in also discharging the starter battery.

Low voltage drop due to the use of high efficiency Schottky diodes.

The Cyrix battery combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a preset voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged).

Cyrix battery separators are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
