1. On the batts....w/the hyperion it should tell you the % in the batt.
2. When you tried 6s were the batts wired correctly together as 2 3s packs in series or was it a single 6s pack?

On 6s that should almost be uncontrollable so something is definitely wrong. I would first check batts for fully charged, then check esc settings. Make sure voltage is correct, punch control etc...
