Size is everything, and the customer says they would rather not use Lithium, but silver oxide cells. I would therefore require 2 to get greater than 3V.
I'm looking at the SR41 and 48W cells but struggling to find any sensible way of mounting them. There are some SMD holders but they use quite a large footprint, from a 7.9mm diameter cell to a width of 13.4mm.
I might have to drop size further but would rather not.
Has anyone else come across this problem in sourcing cell holders? Or some means of attaching power from cells to a circuit.
I would be grateful for any steer.
