I am looking for feedback on my batteries. They have recently dropped instantaneously from 50% to critical low and forced landed bird. Not just one particular battery but a few of them.
Note when I look at the Starlink app battery screen, it shows battery life at 70% (bottom left of screen). This number is not charge status rather based on something else? Perhaps how many times battery was used or cycled or even age. Regardless, my batteries are all showing about 25 recharges. That does not seem like enough to affect cell life. These batteries are 3 yrs old.
Would me performing full flight times and recharging help ?

This is common when you don't charge/top them up within lets say 24 hours before flight even if they show as full. That's how sudden drops usually happen. It's happened to me with 2 batteries that I charged 48 or so hours before. Autel asked for info and replaced one of them but this sounds like you didn't charge/top them off recently before the flight.

Also, do a search of the forum for "sudden battery drop" and you'll find out a lot about it.

This has happened to me many times, and from my experience Tufargon is exactly right. Top batteries off before flying within 24hrs. If you don’t — sometimes everything is fine, sometimes it suddenly, w/o warning, lands immediately, no matter where it is.....

I’ve had my XSP for a few years now and have only flown it a few times because of all the threads I’ve read about this happening. i have a question just to be more clear that I thought you might know the answer to. When the critical battery warning kicks in and the drone auto lands, does it just drop down exactly where it is when the warning happens or does it return to the home point? It seems really terrifying if it drops wherever it’s currently at. The few times I’ve flown my XSP I haven't gone more than 20 or so feet in any direction because this is so concerning. Thanks for your time and hopeful reply!

No, it means it has about 20-30 sec of juice left. You can, in that short window, persuade in one direction or another a bit, sometimes enough to get it back from over the ocean to the shore — which happened to me once. Altitude is your friend. It landed just fine, if a long walk away. One time over big waterfall, it didn’t have enough juice to get out of the gorge. It was a newish battery, full charged, as the flight log proved. Autel replaced the drone b/c it was a faulty battery.

I wouldn’t be afraid to fly because of this. Take care of your batteries meticulously, and they’ll take care of you. Occasionally batteries just go bad. Nothing you can do about it....but how often do you fly over terrain that’s totally inaccessible? Or over water? I do both all the time. If it goes down, I go get it. OK, one time I hired a kid to climb down a cliff to get one I crashed from not paying attention!!

I’d worry more about looking where you’re going, and never talk to anyone while flying, :)

Well I’ve only flown above my house so far. So I’m afraid to take it above anyone else’s property in case this happened.

Go find a large open space, and fly around until you get more comfortable. Try different maneuvers, up/down, circle. It took me awhile to get there, as I believe is the case for most of us in the beginning. Baby steps...
