I’ve just finished building an 18650 Samsung 30Q pack with these nickel strips.

I had to spot weld two layers of nickel strips, since one layer will only do 3A continuous without getting warm and will blow fast at 8A per cell.  
Now with two layers I have 6A continuous and 16A fusing. Times 14 cells this is 84A and 224A max.  
I’m running the pack with a 200A Smart BMS…

Here are the pics:
