Victron Solar Battery Protect 12/24V 220A

The BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.

The Cyrix-ct battery combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one battery 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 both batteries are being discharged)

Cyrix 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.
