Might be better off just daisy chaining them. No idea what other issues that may cause with two on the same bus.

Could you explain what you mean by daisy chain them?

CAN is a single bus that you attach multiple endpoints to.

So, depending what model GX you have, you would have a terminator on the battery side, connect the BMS to the first BMS CAN port on cerbo1, then connect the second BMS CAN port to BMS CAN port 1 on Cerbo 2 and a terminator in the remaining port.

In theory that should work, but never tried it myself, nor could I say what the effect of two GX's on the same bus might be.

Yes daisy chaining the GX devices BMS Can port is like using a splitter cable. I am concerned about the software side - will it work?
