I have had this battery for several months, I use it in a transmitter instead of 6 AA batteries. I can not really say how many flights it will last, but it lasts me for a month at least with several flights a week. Much better than using AA Nimh, alkaline, or any other batteries I have tried in my transmitters. I like it so much that I ordered a 9.9 volt life battery from Value Hobby for my walkera Devo 10 transmitter. Took less than a week to deliver to Texas. I also ordered a 1300mah 2s lipo and it came well balanced, well packaged and at the proper storage charge. Good Lifepo batteries are not that easy to find and sometimes expensive. I have recommended these batteries and Value Hobby to others.:)
