The middle 'best' diagram doesn't indicate that you also make each cable to each battery the same length. Farthest battery sets the length and the closer batteries just have a little extra cable. This ensures that the connections from bus bar to battery are all the same voltage drop under load and during charging, giving the best possible balance between batteries.
