Real Battery Strangeness

I'll hook them up and look. No swelling, under 18 months old, not a lot of cycles.
But a lot of time just sitting there with a full charge?
Unfortunately this is bad for LiPo batteries and that's why you have a problem.
They need to be stored at around 50% to prevent problems developing.
 
Meta is right . Maybe try running them down to about 8% and then recharging them will revive them. Worth a try over chunking em .
Read in here awhile back to do that and did with one of mine but it had a bad cell so no dice .
 
Yes, they have probably been stored at full charge, which I know is bad. I have "normal" lipos for other craft that I keep at a storage charge because I have a charger that can do that. I don't know how to discharge the batteries for the Phantom.

But if I had stored them improperly I'm not sure it would display this behavior. They would run down quicker, right? In my case, the percentage shows 60%-70% but the battery warning flashes and it wants to land. Wouldn't the percentage be lower?
