Victron Energy Cyrix-Li-Charge 12/24V 120A Intelligent Charge Relay
This intelligent charge relay from Victron Energy is designed to connect a battery charger to a lithium (LiFePO4) battery bank, with a 3-second delay and immediate disengagement if the battery's cell voltage or temperature becomes unsafe. It works seamlessly with a VE.Bus BMS to protect your lithium batteries and ensure optimal charging. At $37.83 (compare at $75.65), you save 50%—a fantastic deal for reliable battery management.
The Cyrix-Li-Charge connects the charger when the control input is active (voltage present). It disengages immediately if the control input becomes free-floating (signal from BMS) or after 1 hour to check if the charger is still needed. This smart logic prevents overcharging and ensures safety.

How does the Victron Cyrix-Li-Charge work with a VE.Bus BMS?
The Cyrix-Li-Charge has a control input that is connected to the VE.Bus BMS's charge disconnect output. When the BMS signals an alarm (free-floating), the relay disengages immediately to protect the battery from overvoltage or overtemperature.
How to wire Victron Cyrix-Li-Charge 120A?
Connect the charger positive output to the relay's INPUT terminal, and the battery positive to the OUTPUT terminal. The control input should be connected to the BMS charge disconnect signal. Follow the manual for detailed wiring.
What is the difference between Cyrix-Li-Charge and Cyrix-Li-Load?
The Cyrix-Li-Charge is used to connect a charger to the battery, while the Cyrix-Li-Load is used to connect loads to the battery. Both have similar logic but serve different purposes in a lithium battery system.

Works perfectly with my lithium battery
This relay is exactly what I needed to safely charge my lithium battery from the alternator. It connects when the engine is running and disconnects when the BMS says so. Very happy.

Good, but mounting holes are small
The relay works well, but the mounting holes are small for the included screws. I had to drill slightly larger holes. Otherwise, everything is fine.

Not what I expected
I thought it would act as a battery combiner, but it's specifically for charging lithium with a BMS. I installed it, but it didn't work as I expected because my BMS doesn't have the right output. My mistake.

Great for marine use
I installed this on my sailboat to charge the lithium house bank from the engine alternator. It's robust and reliable. The connection is clean and it handles 120A easily.
