Reducing cell-to-cell contact resistance

[Battery Guy]

If you put batteries in parallel contact resistance doesn't go up. The current distribution through the sets of cells in parallel goes down and therefore the voltage drop and I squared R losses for any set of contacts should not be any higher than before. You have a misconception.

I do not have a misconception. I was just being an idiot. You are, of course, 100% correct. I am quite embarrassed. I don't know wtf I was thinking when I wrote that. Thank you for pointing out my mistake gently.

Cheers,
