Cell configuration for 2P4S

[mitiempo]

I am building a 12 volt bank using 8 Calb CA180 cells. The space I will be using only allows for the 2 cell arrangements shown. Which do all think is best?

In general, I prefer the 'boxed busbars' shown in B for Parallel-First arrangements. However, for 2P the two arrangements are pretty much equivalent. (B has a very slightly lower total resistance.... but not enough to really matter.)

Note: The boxed busbars become more important when the number of cells in parallel is 3 or more.
