It doesn't help the situation, but Victron hasn't done any testing or compliance with REC BMS.

Tested and supported batteries are listed here - https://www.victronenergy.com/live/battery_compatibility:start

I will move this to the modifications section.

Hi @Double Joy

Did you select the correct CANbus speed?

Old thread. Still, did you find the solution?

With the Cerbo GX it works if the can cable is connected to the VE.can port, and the Can bus profile set to >VE.Can and CAN-bus BMS (250kbit/s)<.

I'm using REC in multiple installations and havent had a problem ever since.

with the update from REC (talk to Mr. Andrejasic) you can even see the single different cell voltages in the GX display. I would recommend it to everyone, cheap and very reliable.

interesting, I got the information from REC that this is not possible. Do you see also cell resistance and when balancing occurs?
