I'm looking at building a 2p4s battery in this configuration. I was wondering if I could make the top and bottom buss bars from a single piece of copper rather than making individual cell to cell buss bars. The only down fall I could think of would be expansion and contraction of the cells but I don't see how it would be much different if they a both tight. Anything I'm overlooking?
