RC Log - Battery log - Anyone use this app?

[RipperFox]

I found a slick little app that keeps track of battery charges, flights, charging statics, etc. You can create bar codes so you can just scan you battery events. It graphs battery performance data helps analyze your batteries. Its called RC Log. I figured it my be helpful in prediction a battery failure/disasters.

The app is wanting some info about our batteries (Phantom 2) such as Max discharge rate (C), max loatrate (C). Was wondering if anyone had these specs...
