Adding new batteries
Power everything down (solar DC, AC, batteries) then isolate the batteries. (See video on this group for how to do all this).
I then disconnected the earth and power from the BMS to the top battery, added the new bracket, and refitted the BMS. Then insert new battery and connect earths and power (basically matching what your installer has done).
There’s a dial on the BMS which you point to numberOfBatteries - 2. If you have 2 batteries now it’ll probably be at 0, so after 2 more batteries you’ll want 2.
Double check everything and reverse the switching things off procedure again from video on this group.
Then set the batteries to force charge for a few nights to let the BMS settle.
