Negative connection off a parallel busbar - top middle or bottom?
#1
I was about to make up 5 of these packs (4s14p) for my sons electric motorcycle conversion (Lead to li-ion 20s14p) and recall an article indicating that I should take the connection from the opposite end of a parallel busbar due to the energy moving from + to - accross the series and so both connection being on top could put more starin on the top cells in each parallel.

Unfortunately after questioning myself and whether I just made that up in a dream, I can no longer find the source for the logic, so my question is should I go with a or b, or something else.

Thanks in advance for your help and if anyone has a link to any decent articles (or search terms I can use in Google :-) 

   

The bus bar will be connected with axial fuses
