Thats pretty classic description of a the way damage impacts a lipo. This was what I thought when I saw your thread. Has it ever gotten hot? What do you see for IR when you charge the pac?

If you're putting 95% of capacity bnack in the Hyperion lipo, what are you running as a low voltage cutoff? Its either an overrated lipo (which isn't bad at all) or you're running to a pretty low lvc. You are supposed to get better life if you only discharge them to 80-85% instead of going to the lvc everytime you run them.

Was the zippy any diff during your 1st few runs? Just curious.
