I got my 50c / 5600mAh Fantom battery tonight. I charged it up and tested it briefly comparing it to the 40c / 3200mAh batteries I had been running in my Hyper 10sc. WOW! I could tell right away that there was more power and a much bigger punch. I was hoping that this pack would make a difference, but I wasn't prepared for how big of a difference it would make. The saying, "You get what you pay for" is true. This battery cost more than others but I believe it is worth it.
