I just curious on your all's opinions on this idea. I ordered 4 48v aolithium batteries. I know the cables aren't ideal by any means. But I was thinking of setting two sets in parallel then to a 600 amp bus bar fed to the inverter. Any issues with that or should I just hook each battery to the bus bar? Thank you!

What is the output of the inverter? 6 kW? The 2 parallel stacks should be fine for the wires supplied. They can do 125A max and over 4 packs is around 32A each.
Output would be 5kw. Thank you!

Ok so max current discharge would be about 25A per pack or 50A per dual stack if current sharing is optimized. I don't see any problem. A single stack would get close to max but still within spec. AOLithium does state the 4x parallel format is for up to 5kW systems.
Keep an eye on current sharing and to some extent the SOC (but unless you have high idle draw the SOC is a waste of time).. Most can't detect below 0.5A (about 50W). So in a bank of 4 you would need to have over 200W continuous idle draw to keep the SOC reasonably accurate. That's my experience but happy to hear more from the experts.

I definitely appreciate the input. Fairly fresh into this. I know basic electrical concepts I'm a lead maintenance tech. But solar is definitely new to me lol

I think this guy is doing what you suggested.
Yep that is what I do. It solves the issue
