Neok,
None of the answer you got are really wrong, but would you like an real solid answer??
It won't matter.
Two 12V batteries that are so far apart will never balance anyway. It will simply be impossible to charge or discharge both the same amount. Not just because of the wire between them, but also because they:
* Were not matched to begin with,
* Will always be at different temperatures,
* Will get different levels of care,
* They are going to charge and discharge differently do to the resistance between the jar and the activity.
Parallel batteries are very hard to keep matched. There is just nothing that can be done about that. When installing paralleled banks (I never like to) I used a special instrument to balance the connecting cables to 0.01 ohms. If the owner called and said he had lost capacity, I would tell him to clean the cables ends and recharge. Or I could come and do that on his dime.
