I have three of these. The first one came in the box with my Blade SR RTF ( Original SR) purchased April 2012. Well its 2016 and I still get three minutes on this 4+ years old battery. This is remarkable since for about a year while learning to fly with my Blade SR I cycled this battery at least three times per day..... everyday rain or shine as I used the now demolished indoor parking lot in Hollywood Beach Florida. I have since purchased two spares packs and all three are still working. I only wish my Blade 500 6S battery pack was of similar quality !!!

I got mine at my local Hobbytown, and got it home and put it on my charger. All 3 cells were at 3.66V perfectly balanced, it charged quickly and my charger said it got 350Mah on the charge. My first flight test I thought was fluke, so I recharged the battery and did another one. Nope, not a fluke I got 11 min hover time on my 250mm quad on this battery. My Turnigy 1000Mah battery only gets 6 min hover times. What?!? almost double my flight time? I thought perhaps I got lucky and got a fantastic battery. I bought another one last week. Same thing 11 min hover times. I have no fpv gear running during these tests, and i'm only hovering, with altitude and heading lock on. Awesome batteries, they do get a bit warmer than my Turnigys do when really ripping on the quad, but still within operating temps. I can't recomend this little battery enough.

I have been using Thunder Power Lipo's for the last 4 or 5 years. I have not found better lipo's for the price anywhere. That's why they are the only brand I use now.
