Right. That's why I was mentioning solder. I could have been more
careful with my wording, but the point was to provide a better solder
connection.

Just a thought, here. Years ago I played around with electronics using bread
boards and wire wrapping. The wire wrap causes a really tight bond, I was told,
at the molecular level. I wonder if you can do something similar for connecting
cells. At the very least, if you have several turns of wire, your solder will
make a larger and stronger connection.
Done thousands and thousands of wire wrap connections. Remember, that most
wire wrap stuff was working in the milli amp range. As for the connection,
think about this. You have a square pin with normally solid wire wrapped
around it. The only place that has any real tension holding the wire and pin
together is at the corners of the square pin. At the corners, there is likely
a pretty good amount of pressure holding them together, but it's a very small
area of contact.
Note that some wire wrap pins are round rather than square, so a wire wrapped
around it would have a larger contact area, but at less tension.
