2 x Sunsynk 5.32 KW Batteries
So I installed 2 batteries, 4 months apart. As far as I know, they are the same model.
My Inverter (Sunsynk 8KVA) report that I have 204 AH available.

So my problem is I am running SolarAssistant as well with an RS232 cable plugged into master. But SA are
reporting that I have 204AH

Which one is correct or is it a software upgrade or settings issue.

Your new battery should be your master as it has the newest software. Maybe that will help. And you are correct that the battery BMS supply SA with data.
