I have 2 of the 24V 200 Ah lithium Victron batteries in an off grid cabin. I just noticed a slight difference between them, I wouldn't have noticed if they weren't side by side. On of the battery lids seems to have lifted by a few mm relative to the other which is a flush fit. I don't recall seeing that before and they are only a few years old. The cell voltages all look ok and they are working fine, though I haven't done a capacity test. Is this something to be worried about or is it normal?
