I have a question about the stock battery the cp comes with. Since I got mine I have been charging my pack on my prophet plus charger @ 1 amp. Charge time is usually 30-40 minutes. I've gone through about maybe 8 charges now and my charge time is going down to about 20 minutes and I am only getting 2-3 minute flight with half power. My question is am I frying the pack by charging it on my prohpet plus? Or is it just a dud pack?

Thanks in advance!
