From what I've seen on the 4s and 5s packs, the PCB is just there as a mounting point. The tabs themselves fold over each other, so there is really not much traces being used.

The 5S pack doesn't have the solder trace like the 3S pack does?
I don't remember seeing any, but now that you mention it, there must have been one, unless the last + or - main wire was longer to reach the bottom most tab on one end.
