Frequently Asked Questions
Where can I buy the Victron Cyrix-i 400A at a discount?
Our store is offering it at $51.75 (50% off the $105 list price). Use coupon SAVE15 for an additional 15% off.
How does the Start Assist button work on the Victron Cyrix-i 400A?
Press the push button (or close an external switch) to manually engage the relay for 30 seconds, connecting both batteries in parallel. This is useful when your starter battery is too low to start the engine, allowing you to use the house battery to crank.
Can I use the Cyrix-i 400A with lithium batteries?
Yes, but make sure the lithium batteries have a BMS and that the Cyrix-i doesn't cause issues with high inrush currents. Victron recommends using the Cyrix-Li series for systems with a VE.Bus BMS, but the Cyrix-i can work in simple lithium setups.
How do I replace a diode isolator with a Victron Cyrix-i 400A?
Disconnect the diode isolator, then connect the alternator/charger output to the Cyrix-i's INPUT, and the two battery positives to its OUTPUT terminals. Ensure the Cyrix-i is properly grounded and mounted. This eliminates voltage loss and improves charging.

Great upgrade
I replaced my old isolator with this combiner. It's much better because there's no voltage drop. Installation was easy. Highly recommend for any vehicle with dual batteries.
