Can I connect two GX devices to one battery using a RJ45 splitter?

Could you explain what you mean by daisy chain them?
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.
