A friend was doing the math about a Masione 16000 22.2v 25C "Designed for the DJI S1000 !" battery I was using for my S1000, and calculated that, fully-charged, it was giving me the first low-battery warning (set at 22.1 volts) after about 2 minutes of flight time because it was only giving me perhaps 8C discharge and/or it was not really 16000mAh.  
But I said "Look at the sticker...it is designed for the DJI S1000!"

He remarked that "Yes, that is the problem with most batteries:   The maker just puts any sticker it wants on it.  It is just a sticker."

My faith in my fellow man is shaken and I realize I am a rube, but how in the world can we find a reliable, fast discharge battery for the expensive drones we have, that can use AS150-XT150 plugs that are standard on the S1000?

The friend simply suggested buying 20 of the same brand/model, try them out quickly, and keep the 2 that actually work correctly.

There must be a better way.   Ideas, suggestions and rants accepted here...  -Peter

Hi Peter,

your friend is mostly right :-( The only facts are the tech specs...

Even with my very new and expensive Tattu 16000 the first 3-4 flights with a s900/Z15/A7 were 3-4 min. It encreased later to 14-16 min. They are described as specially made for the s900/1000, but this means only the dimensions.

"Increased" after a few flights?  Didn't know that could happen.  Will give my Tattu a few more tries...  
Thanks. -P
