Victron Energy Cyrix-ct 12/24V 120A Battery Combiner Kit Retail

This Battery Combiner Kit is designed for adding a second or third battery system to your car, boat, RV, or any other vehicle. It uses advanced technology to keep all your batteries charged using the engine’s electrical system while isolating the starting battery when charging ceases to prevent stranding. The Victron Energy Cyrix-ct 12/24-120 is a bidirectional voltage-sensitive relay that also engages if, for example, the accessory battery is being charged by a battery charger. Its intelligent battery monitoring software does more than just connect and disconnect based on battery voltage with a fixed time delay; it observes the general trend (whether voltage is increasing or decreasing) and only reverses a previous action if the trend has reversed during a specific period. The time delay depends on the voltage deviation from the trend. Installation is easy and does not require cutting into any factory wiring, thus avoiding any potential voiding of the manufacturer’s warranty on your boat or vehicle.
