Charged 2 batteries, both showed 100%.  First battery performed as expected: total air time 28 mins.  2nd battery showed 96% on take and landed 45 seconds later showing 0% battery power on controller.   Went home, recharged the 0% battery and it was showing 95% on my charger when I hooked it up.  SO,  is it the battery or the drone?  Anyone else with a similar experience.

Hello there Amocat07. I am sorry for the trouble this has caused and thank you for reaching out. May we know what is the model of your DJI drone and when did you purchase the said DJI drone and the said DJI Intelligent Flight Batteries for us to be able to assist you further? Thank you.
