After assembly I got this information from the app. I rearranged the individual cells so that none of the original cells that were in 10 or 9 were in those positions and got very similar results any ideas?
I would imagine your problems are down to poor contact. Are you tightening down enough? The issue I had was the type of contact surface on my Samsung 35E cells. They look like a matte finish not shiny and under a strong magnifying glass or microscope have peaks and troughs. The cell holder contacts are very fine and have a little difficulty making a good contact, even arcing during use. The solution was to smooth out the contact surface to eliminate the peaks and troughs allowing the cell contacts proper connection. It’s been fine ever since.
I tried tighten everything down. No change in the readings
I am taking it as read that you checked the voltages in EVERY cell were the same if with very minor variation? Now have you used a multimeter to check voltage or even just continuity across each end of the cells in the affected banks. If you have cells that have no continuity across the HOLDER end terminals check that cell for voltage and continuity. Any pair of holder terminals that lacks continuity yet the battery reads OK means that that cell is not making contact with the holder or you have broken traces. Inspect the holder terminals for broken traces. The trace acts a fuse against incorrect assembly. You can repair them with solder. I suspect you do have broken traces in Bank 9 so repair those first. Check ALL the cells again for charge level and charge them individually to the same level. Ensure all the battery terminals are not damaged in any way then reassemble. Let me know how you get on.
Here is the links referring to broken traces.
