My new Eve 280 ah battery cells from Amy Wan have finally cleared customs and should be at my door tomorrow. I purchased 16 and confirmed that she only sent me 16 bus bars. I'm planning a 4p4s configuration for my bank and will be making my own bus bars out of copper bars purchased on Ebay. They're 1/8" thick and 3/4" wide. My question is if there's a problem with having long bus bars traversing 4 different cells, each approximately 11" long. My configuration will look something like this (picture found on internet, not mine):
I was going to cut 8 bars to size and mark the top of the cell posts with a little marker and press the bar on top while they were still wet to see where I would need to drill the holes. I was also going to apply the protective shrink wrap in-between the holes. The only disadvantage I see is that this is for a mobile system that will see bumps and much more movement and the battery won't have maybe as much "flex" room to shift around, which may create stress on the posts (welded). However, they will be compressed and fixed to an an aluminum shelf as below. Any thoughts?
