I emailed flightpower asking about their packs and cells comparing to hyperion. I'll tell you if I hear back.
I don't think hyperion and flightpower have the same cells because: Flightpower EVO-X LITE advertizes 25/40c while Hyperion advertizes 25/45c. It could be a conservative rating, but I think on the cell is says the capacity and c rating so the company can't really change it. There is a possiblity and it would be really cool if they were the same, but I don't see it.
And prices, do you mean with every pack?
