Description of Victron Energy Cyrix: Efficient Battery Combiner for Optimal Power Management

Intelligent battery monitoring to prevent unwanted switching: The Cyrix-ct 12/24-Volt 120 amp looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time. The time delay depends on the voltage deviation from the trend. Protection against overheating (due to a long duration overload): The Cyrix will disengage in case of excessive contact temperature, and reengage again after it has cooled down. Parallel connection in case of emergency (Start Assist): The Cyrix can also be engaged with a push button (Cyrix remains engaged during 30 seconds) or a switch to connect batteries in parallel manually. This is especially useful in case of emergency when the starter battery is discharged or damaged. No voltage loss: 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. 5 year warranty.

Efficient power management is key

If you're looking for a reliable way to manage your boat's battery, Victron's Intelligent Battery Combiner is a top choice. It combines two battery banks automatically with minimal power loss, so you never have to worry about running out of power on the water. The compact size makes it easy to install, and the LED status-indicator adds convenience. While the price may be a bit steep, the peace of mind and energy efficiency are worth it. Perfect for Sports and Outdoors enthusiasts.

  • Efficient charging and maintaining of multiple batteries, preventing overcharging and ensuring longer battery life.
  • Relatively expensive compared to other battery combiners in the market.

Just what I needed to charge my camper when towing!

I used this in an old camper van that I converted as an automatic switch between the tractor and camper battery. It allows us to charge the camper while towing and automatically turns off when the tractor is turned off, preventing the camper from draining the tractor battery. So far it's working great!

  • Intelligent battery monitoring to prevent unwanted switching: Cyrix-ct 12/24 V 120 ampere monitors the overall trend (voltage increases or decreases) and only cancels the previous action if the trend has changed within a certain period of time. Time delay depends on voltage deviation from trend
  • Useless functions

Affordable price and availability in Canada.

We have an old motorhome from 1984 and the only way to charge the starter battery is by (a) starting the engine or (b) connecting an external charger/maintenance device. I have used an external charger at a serviced campsite in the past to keep the starter battery always ready to go. I've read about these devices from other RV owners and thought they would be a good way to keep the starter battery charged when the RV is connected to shore or solar power. No external charger required. I also…
