Description

Victron Energy Cyrix-Li-Charge 12/24-120A

The Victron Energy Cyrix-Li-Charge 12/24V 120A is an intelligent charge relay that connects a battery charger to your lithium battery system when charging is safe. It works with VE.Bus BMS or similar BMS systems and disconnects immediately if a cell overvoltage or over-temperature signal is received. Now at $37.83, you save 50% off the $75.65 list price, plus extra 10% with code SAVE10.

Specifications

Brand: Victron Energy
Model: Cyrix-Li-Charge 12/24-Volt 120 amp
Product Type: Intelligent Charge Relay
Max Current: 120A
Voltage: 12V / 24V auto
Control Input: Floating (BMS signal)
Features: 3-second delay on connect, 1-hour disconnect check

Compatibility & Use

This relay is designed for lithium battery systems with a BMS that provides a floating signal (e.g., VE.Bus BMS). It connects the charger to the battery only when the BMS indicates it's safe, and disconnects immediately if overvoltage or overtemperature occurs. For wiring, connect the coil to the BMS signal and the main terminals in series with the charger output.

Value & Savings

At $37.83, this is a 50% discount. Use code SAVE10 for an additional 10% off, making it $34.05. Free shipping on orders over $45.

Features

Smart control: engages charger only when BMS gives safe signal, disconnects instantly on fault.
Universal voltage: works with 12V or 24V systems automatically.
Half-price deal: $37.83 instead of $75.65, plus 10% off with SAVE10.

Frequently Asked Questions

How does the Victron Cyrix-Li-Charge work with a VE.Bus BMS?

The Cyrix-Li-Charge is controlled by the VE.Bus BMS. When the BMS sends a floating signal (i.e., no alarm), the relay engages, connecting the charger. If the BMS detects a cell overvoltage or overtemperature, the signal goes low, and the relay disconnects immediately.

How to wire the Victron Cyrix-Li-Charge 120A?

Connect the charge relay's control input to the BMS's charge disconnect output. Connect the main positive and negative terminals in series between the charger and the battery. Ensure proper gauge wire (e.g., 2/0 AWG for 120A) and a fuse.

What is the difference between Cyrix-Li-Charge and Cyrix-Li-Load?

The Cyrix-Li-Charge is designed to connect and disconnect a charging source, while the Cyrix-Li-Load is for load disconnection. Both are controlled by a BMS signal, but they serve different purposes in a lithium battery system.

Can I use this relay with a non-Victron BMS?

It can work with any BMS that provides a floating output signal, but you must ensure the logic is compatible. The Cyrix expects a voltage-free contact or floating signal. Consult the spec for exact requirements.

Where can I buy this at the best price?

Works flawlessly

My lithium battery charges automatically when the alternator runs. No more worrying about overcharging. Install was straightforward.

Good product, few quirks

It does what it should. The relay engages correctly and the voltage settings are adjustable. Only downside is the instructions could be clearer.

Reliable charging

I use this in my van to charge my LiFePO4 battery. It's been running for months without a hiccup. The unit gets a bit warm, but that's expected. Very happy.

Not for all setups

I thought it would work with my system, but it didn't. The relay kept cycling. Maybe it's my battery, but I had to return it. Check compatibility first.

Works, but pricey

It does the job. I like that it's for lithium specifically. Installation was a bit cramped, but fine. Would have given 5 stars if it were cheaper.

Essential for lithium upgrades

If you're switching to lithium, get this. It's plug-and-play with my charger. Set it and forget it. The voltage cut-off is accurate.

Burned out quickly

After a couple of weeks, it stopped working. No indication why. I followed the manual exactly. Poor quality control, I guess.

Great safety feature

I like that it automatically disconnects when the battery is full. Gives me peace of mind on long trips. Wire gauge is adequate. All good.
