Only 600 mAh and thinner
I tested this no-name LiPo battery on my helicopter because of its low price. It seems to do nearly as well as my original Walkera battery. The model I got only showed 600 mAh printed on the surface, instead of the advertised 650 mAh, but no problem with that. The battery is slightly thinner than my original, so I had to stick a piece of insulating tape on it to prevent it from sliding out of my battery holder, but this is no problem either. I consider buying more when my other batteries get weak.

I bought 5 batteries to use with my Walkera 4#6S and 4G6S. They fly great with these batteries. It's smaller than stock Walkera but fits perfectly on battery holder tray. Avarage flying time is 5 minutes. I expected a minute or more than 5 minutes but considering that the stock battery is 600mah, and this one is a quarter of a price it's fair. I really will buy more of this batteries.
