One of the things that could cause the symptoms you describe on the AIMS, is leaking capacitors. Look for any that have even a slight convex arc on the top caps, they should be completely flat. AIMS were never engineered that well to begin with and they put a lot of stress on their undersized capacitors. And if they aren't Japanese capacitors they will likely last less than 20% as long as they should.

My Victron Multiplus II 12V 3000VA even causes my 12 volt lights to flicker even with unit on and bypass etc. I am only using it on some light circuits (20 amp) as build and test the system. I think it has to do with the battery capacities in relationship to the inverter parameters. We can have too big of an inverter for battery capacity. If you can regularly reproduce the issue, it might be nice to simply stack up with more capacities

I would expect some flickering, but this is BAD flickering. For example, when I start my 5000W cloths drier, the 120V legs drop from 115V to low of 70V. When I run the same drier on a pair of LV6548 with a significantly smaller battery (the 4x SOK) it only drops from 120V to about 115V. Crazy difference.

The tapped holes I drilled in the compressed parts for the BMS balance lead screws are still solid as well.

After months of using and slowly squashing back to somewhere near their shape, he did a capacity test to see how much value he had lost from this catastrophe, and the results were he still had nearly 90% capacity he was able to draw with a 40A & 100A test, so I would say they are a pretty robust cell if they can cop that and still perform so well 6 months later.
