It's not likely that the remaining cells are in 100% condition.
Also, the bottom cell in the pic above actually looks like it might be slightly puffed. A good cell is completely flat... no curve to it.
One of those cells has to be swelled...
I had a pack that had a very slight puff to it... barely noticeable. It lasted a long time like that but eventually did get worse and puffed more. That was a pack that got taken out with an ESC meltdown.
I think the non-copper tab is tin, not aluminum...? Alum is very soft and requires special flux to solder.

I am going to run this pack, just to see how it does. All of the the other cells are fine, no bulges, or puffing. I had a good look at them. Plus they were all in balance when I got the pack, a bad cell would lose voltage slowly. I will leave it fully charged and see how it does. The tab looks to be just like MA old cells, and they had al tabs, and required zinc sloder and the correct flux. Plus they were very fragile, and fell off easily.
