No, there will be no imbalance IF they connect to the batteries in a balanced manner. The current through each cable will be the same. Ohms law indicates that in a series circuit the current remains the same while voltage drops across any resistance.
Correct. The only lengths that need to match to be balanced are the short parallel jumpers between the top and bottom battery sets. The idea is the extra length to get to the negative side is canceled by the shorter length on the positive side for a given 12v battery pair and vice-versa.
