1. Lithium batteries are extremely expensive. Some 4 to 10 times more expensive per watt hour than their lead acid cousins. That alone justifies a balanced charger.
2. Initially you are right a 100 mv is not a lot to worry about. But liithium batteries are extremely sensitive to over charging. The weakest battery in a series string will have the highest voltage applied during recharge. That results in an over charge condition of that cell and under charge of the normal cells. With each cycle the damage is compounded and accumulative causing premature failure. Now go back and look at reason #1.
