I need to build a battery box to hold 8 c cells. I'm thinking to possibly break from tradition and try using stainless steel sheet material to make the contacts from. I know it's not the easiest to make a soldered connection to, but I could always lay out a dozen or so contact strips and melt a dot of silver solder to each one. Then I should be able to solder to them easily after that. Hmm- might even lay a dot of silver solder on the contact side as well. I wonder how much better of a connection that would make to a cell terminal- if any better.
The stainless should give a more solid and long lasting contact pressure against the cells- this is what I'm thinking anyway. I usually just use brass strip, but it doesn't really hold up well in that regard. Enough jostling and some of the spring pressure will have been lost.
Stainless seems a better match to the cell terminal metal anyway, in terms of dissimilar metals- though I could be wrong. Any thoughts welcomed.
