Just because your battery is not on the compatibility list doesn't mean it won't communicate with a Cerbo.

The Cerbo doesn't have a an RS485 port, so CANBMS port would be the one to use (you will need a termination plug in the other CANBMS socket too). You will also need to obtain or make the correct cable as the pin arrangements differ between battery manufacturers (you would have to get that info from Fusion). Personally I would start with trying a Victron type A or B cable. If your battery has dip switches I would try all off to start with, and if that doesn't work then try address 1 (dip no.1 set to on).

The battery should appear in the device list of the Cerbo if it is communicating.
