    CYRIX-LI-CHARGE 12/24-120A Intelligent Charge Relay Cyrix LI ChargeThe Cyrix Battery Combiner is a microprocessor-controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set 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 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.Please contact your dealer for any returns, repairs or support issues related to this product.
