Hi BFL13,
No, the extra resistance (yes I know it is small) causes a slight voltage drop. So you have a choice of over charging the middle battery and getting the charge "just right" for the other two, or charging the middle battery "just right" and having the other two a smidgen under charged.
Does it matter? Perhaps not. Especially for a person such as yourself who separates the banks and fully charges when you get home after a trip.
I preferred to balance in the first place so that I would not have the issue to deal with. (but that is MY rubber ducky, LOL)
