Very minor difference in busbar size between lifepo4 cells

I had to create 3x busbars with a different thickness to the ones that came with my EVE lifepo4 cells. The main reason was to successfully connect one pair of the parallel cells in series successfully as illustrated in the photos.

The new busbars are 1/8" thick, unsure of the size of the busbars that came with the cells.

I am concerned this is going to create an issue with my battery bank in terms of their charging/balancing. However, I really dont want to get the hacksaw again and make half a dozen custom busbars with the copper length that I bought (very time consuming). I've read of an importance of ensuring cables are of equal length to account for resistance when running stock 100aH batteries in parallel in order to extend battery life.

How problematic is this very slight difference in thickness?
