Victron Battery Combiner / Isolator
The Cyrix-ct 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).
It automatically detects wether you system is on 12V or 24V.
There is virtually no voltage loss when you use this, meaning you don't have to buy expensive, thick cabling.
It is protected against overheating.
When you starter battery is damaged or discharged, you can use this and your other battery to jumpstart your vehicle.
Cyrix-ct battery combiners 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.
Can be used with the HBC Dual Digital Battery Monitor
