I’m considering a staggered double stack vs staggered triple stack layout for a pack because reasons, had a couple questions

  • Any thermal problems with this? I tried finding any mention of pelicase packs overheating easily and failed, so I’m guessing the effect of thicker p groups would be relatively small. Not expecting the pack to see hard continuous use anyway

  • Is it feasible to pull 60-70A all the way across the nickel on a triple deep p group to a tab at the top (which would be 2-3 cells wide)? Or would additional series connections at the bottom be required? The conductor chart indicates that 0.15mm is sufficient for my max load of 30A per 21mm width (and 0.2 is better), but idk if this would pose hotspot issues
