So I'm building my first battery and was curious if my way of paralleling the batteries was sufficient.

I originally wanted to make cutouts of my copper sheet that would cover the whole area but I found that it took a lot of pressure to get the copper down into the pits made by the battery holders and that made me uncomfortable. Also once the plate was there it was hard for me to visualize where I would need to place the sandwich strip and make my welds. I opted for copper strips to make the series connection with overlapping nickel strips to make the parallel connections.
The uneven strip was the last one I made. I noticed during the first 3 parallel strips that welding on top of the sandwich welds caused those welds to weaken. At least I'm pretty sure as I heard a metallic popping sound as if a weld was letting go. Hence why I made many extra welds at other locations on the first 3 strips.
I figure as long as every battery has a electrical path to every other battery in the parallel group then the strips don't need to connect directly from one battery terminal to the other. But I'm not a electrical engineer so I don't know that for sure. Any advice or info on this would be appreciated. Thanks!
