The is no heat.
You can see that each 16S is on 2 rows and parallel is between each every 2 cells , please open the image and see the connections of batteries and also on the end are the inverters. Also for better balancing inverters will be moved at series ends, now they remained from first 2 series of 200Ah and i just added 2 more series of 16s of 310Ah. The setup is for long therm storage and load is not too high. Also using 2.5mm2 balcing with WAGO allows me to add up to 5 x JK Active BMS to work in parallel. I consider having all batteries as one pack and connecting4 or more inverters to the same pack better than using separate pack for each inverter (not possible with parallel setup also, so it should be same battery pack).
Heat is irrelevant to the discussion. Telling me that you have no heat does not mean that this configuration will perform well (whether it's short-term or long-term).
I did look at the picture. I spent a lot of time studying your picture. Please assume good intent on my part; my points still stand - I do not recommend this configuration. It's still your choice but I recommend flat bus bar connections and balanced power flow. You appear to even have different size cells in parallel.
Have a look at what I found with terminals that were apparently dirty (but there was no visible indication it was dirty, there was no heat, and there were no performance problems):
That particular issue would have, over time, caused issues. I *guarantee* you have the same issue with your current configuration. You have different C rates throughout your entire pack which will age the cells differently which will cause balancing issues that no amount of active balancing can correct.
If my reasons still aren't clear, I'm happy to clarify further. You asked for input - I'm giving it to you.
