I think I found the issue. After 1 run at the track today I immediately put the pack on the charger individually. The first pack was greater than 3.8v per cell. I removed it and placed the second one on and it had one cell down to 2.89v wtf. So I may have a bad pack with a bad cell.

On another note before all this occurred I was really looking at the packs and they all seem to be slightly thicker in the middle, not perfectly flat. I have 4 packs which I aways run together and don't mix. Also keep in mind all brand new, all have 2 runs on them, always balance charged at 1c, always storage charged, stored in a cool basement. Also not really ran that hard as trying to make it around the track on all 4 wheels. I showed a knowledgable guy at the track and asked if they looked puffed and he said absolutely not. I was being paranoid, but then this crap happens. Wondering if I should try to get my money back from hobbyking.
