Unless all the cells in your pack are fresh and manufactured on the same date, or at least balanced before hand, chances are you'll have a bad pack.
I had a guy at prairie battery add a cell onto one of my packs without balancing it first and it killed my pack after I used it.
Tamiya connectors suck.
