That was more like it and for sure it don't look right, does it behave the same if doing same sequence in that speed also when out of AC and when connected to charger?
Still a little unclear to me what the history is, did you buy it one year ago but first start using it now or when has that battery last been flying?
Yes, same sequence when I try to power up (shown in second video) when battery plugged into charger but AC unplugged from wall.
Here’s my recollection:
I flew on that battery multiple times (maybe 20 times) since I bought it with the drone last year - no problems. Treated it nicely according to the manual as best I could (pretty sure I did, at lest I knew not to store fully charged or fully drained, although I most likely would have had higher charge when putting away then lower charge though I may have done it wrong. and that statement shows I would not be a good lawyer- lol.
Put it away about 5 months ago - cannot remember what charge it had - most likely above 50 percent, possibly even above 70%. It sat for 5 months, untouched. So, those 2 factors may have contributed to its current state.
Then, about 5 days ago, I took it out and seeing (I think) 3 LEDs blinking (not sure, I just don’t recall) I thought I would fly it first then charge it. That could be what it did not like. I don’t remember how much of a charge was indicated on screen when I launched so maybe I can get that data from the app?
I flew it until battery went down to 10-15%. Then put on charger - went out and used the other 2 batteries I have, which I put away at the same time but possibly with different status, except I charged them first before I used them recently and they work fine. Tthey were bought at a later date and actually have gray label, not white. Don’t know if that matters as to model/ type of battery.
I did not watch charger so not sure when 16 blinks came but it was on charger for an hour or more and I noticed the battery wouldn’t work after that. I was waiting for the blinking to stop - indicating a full charge - but after more than an hour, it kept blinking. I took a closer look, saw 16 blinks, removed from charger, installed in AC and discovered it did not work.
I’m new at this and still learning. I have at least one short flight on the faulty battery just an hour before charging and getting 16 blinks, so maybe that last flight data will tell something about the battery. Or is the info about batteries not saved for download? I will look into it.
I think I will let it discharge some first then put back on charger - as I’ve seen suggested in this forum. I don’t think it was in hibernation mode which I think shows red light on button - no red light was shown. I used it without charging first after I stored it and, again, that could have been the mistake.
Thanks for your interest in helping to solve this. Hope all of what I wrote there makes sense.
EDIT: Just looked at flight data and it shows I started with 45% battery charge after having stored it 5 months. When I landed at put back on charger it had 19% charge.
