Hi everyone, Thought I would share my experience with you. I've been using only one battery for the last year and a half - probably because I figured it would outlast the P3. But everything is still operational and the original battery life is now down to 71%. (This information is still displayed on the Litchi app even though the Go app has removed it. The cell voltage variation is still very close however, but I know my run time is a little less. I ordered a new battery on Amazon the other day because the price has dropped to $102. They claimed it was DJI. Sounded too good to be true so I waited till I got it to tell you about it. It is in fact a DJI battery in their packaging. I put it in my P3 after charging and it was recognized and updated to the newest firmware. Litchi app shows its life at 100%. So now I can say I got a good deal (Amazon Prime too, with 3 day shipping) Here's the link: https://www.amazon.com/gp/product/B00Y1W5EEU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Happy flying.
