How to Connect a Third-Party BMS to a Victron Cerbo GX
Run the RS485 data cable from your BMS communication port to the RS485 end of this interface, then plug the USB end into the Cerbo GX USB port. Configure the BMS type in the GX device settings to enable battery data monitoring.
Pylontech & JK BMS Compatibility
Pylontech batteries commonly connect to a Cerbo GX via RS485 to USB using this cable. For JK BMS wiring, match the BMS RS485 pinout (A/B data lines and ground) to the interface cable, observing correct polarity before powering up.
RS485 to USB vs. MK3-USB
The RS485 to USB interface is for RS485 devices such as third-party BMS units. The Victron MK3-USB is for direct connection to Victron products with VE.Bus ports (like MultiPlus inverters). They are not interchangeable — choose based on your device's port.

Plugged in and it just worked
Connected my Pylontech battery to the Cerbo GX and the system recognized it within seconds. No driver hunting, no config headaches. This is how integration cables should work.

Reliable, standard length
Works flawlessly between my JK BMS and Cerbo GX. The 1.8m length was just barely enough for my cabinet layout, so measure before buying if your gear is spread out. Otherwise no complaints.

Pylontech to Cerbo, plug and play. Buy it.

Does the job
Data flows fine and my battery comms have been stable for two months. Only gripe is the price for what is ultimately a cable, but official Victron parts tend to just work so I paid it.

Skip the generic clones
I tried a cheap third-party RS485 cable first and spent two weekends pulling my hair out with comms errors. Swapped in this official Victron cable and my Pylontech batteries have reported flawlessly to the Cerbo GX ever since. The connector seating is tight, the shielding is proper, and the firmware sees the battery instantly. Lesson learned, buy the real thing.

Good cable, works as intended
Using this with my JK BMS inverter battery and Victron gear talks to it perfectly. Cable quality is nice with good strain reliefs. Four stars only because I wish they offered a longer version for rack installations.

Fine cable, wrong expectations
Cable itself seems well made, but it doesn't work with my non-Victron BMS without extra configuration that the listing didn't mention. Returned it.
