Victron Cyrix-Li-Load 12/24V 230A Intelligent Load Relay

The Cyrix Battery Combiner is a microprocessor-controlled heavy-duty relay that automatically connects batteries in parallel when one reaches a pre-set voltage, indicating charging. It disconnects when the voltage drops below the float level, indicating discharge. Cyrix Battery Combiners are an excellent replacement for diode isolators, with the main advantage being virtually no voltage loss, so the output voltage of alternators or battery chargers does not need to be increased.
