How do you simulate poor sharing of LiPO cells in battery arrays?

Hi,
LiPO cells in big seires parallel arrays dont share current equally when the array is loaded.....how do you simulate this best?
Is the best way just to put different value resistors across each cell?

Yes, R's across some cells, psu's across others to maintain cell volts ...
