I have received some good input from the DIY Forum, but you guys always add excellent feedback.
Most pouch cells are designed with one tab copper (negative) and the other aluminum (positive). I have read there are issues when connecting aluminum to copper. I have been reading the positives and negatives.
My original plan was to use copper bus bars, but I would like to use aluminum. I have found two grades of aluminum in bus bars that are very conductive:
Grade 6101
Grade 1350

Grade 6101 T61
T61 and T64 are more conductive than T6, T63, and T65
I will plate the copper or aluminum, what ever I decide to use, so my main issue is heat, resistance, voltage loss.
I am going with a 10P cell modules each connected with a 30mm wide block, 19mm tall, and 6.5mm thick between each tab. This seems like enough "meat" between each tab to use aluminum, I am looking for some advice?
Each 10P module will deliver 4000 battery amps+
