I can only give my opinion on this subject as i've used all sorts of lipo battery brands,high priced and low and i've got to say the Hobbyking Nano-Tech and Turnigy batteries are the best i've come across and hold up very well,i would recommend these batteries to anyone who wants a good battery for there money and don't let the low price fool you because you get just as good if not a better battery for your money than you would if you brought the really silly high priced ones,just my two pennies worth.
