Victron Energy Cyrix-ct 12/24V-120A

Cyrix Battery Coupler 120A Battery Disconnect Relay. The Cyrix Battery Coupler is a high-performance microprocessor-controlled relay that automatically connects batteries in parallel when one of them reaches a predetermined voltage level (indicating that the battery is being charged) and disconnects the batteries from each other when the voltage falls below the maintenance voltage level (indicating that one or both batteries are being discharged). Cyrix Battery Couplers are excellent for replacing separation diodes. Their main feature is that there is virtually no voltage loss, so the output voltage of the AC generators or battery chargers does not need to be increased.
