I tend to agree with cts. If you have a large enough voltage headroom, balancing is likely unnecessary. The caps have a sort of self balancing in that they leak relatively large amounts of current as they approach rated voltage, and almost nothing just a few tenths of a volt below.

With my 5-series BCAP3400 2.85v rated caps, there is no headroom, so balancing is more important. With my 6-series BCAP350 rated at 2.75v, I've got lots of headroom. Even so, I still put in balance LEDs because I didn't know better at the time.
