If you have a multimeter handy (and if you don't I suggest you get one), put the positive lead in the positive port and the negative in the balance port and check the number. Then put the positive lead in the balance port and the negative lead in the negative port. Compare the numbers.
It's in balance if the numbers are within .02V or less with each other.
