I've had an early autoland the last three times I've used one battery in particular. It starts off good enough. then rapidly drains after a few minutes of flight. I noticed cell 3 at about 100mV less than the others. After the last full recharge cell 3 is 100mV higher than the others. Is this battery a gonner? https://www.dropbox.com/s/5y8zl35loo3gc ... e.png?dl=0
BATTERY ISSUES (Early Autoland)??? POST HERE

I'm not clear on what you mean by "so" (is this a continuation from an earlier thread?) but my P2 wants to land early on all my batteries. On one of them it wants to land at 70%.
I get not even 5 min flight time with all three of my Phantom 2 batteries. I bought this about year and a half ago and had maybe 20 flights. Kinda pissed actually considering the price of replacement batteries.
Has anyone who has an "early land" battery, tried to recycle it using the very low charge method?
That is, deplete the battery so low that there are no lights and won't come back on ... then give it a full charge ?

I had a battery that had done only 19 charges and then the RC assitant reports a bad battery... Heliguy.com replace it for me.
I'd had the battery for almost a year.. with such a low usage I'd go for the replacement route.
That is a amazing shout out for those guys and is all the reason I would have for dealing with them. Going to check their website now. Most companies would give you the answer I got which was " DJI Phantom batteries have a problem and DJI will only warranty them for three months, sorry".
I did this and it seemed to work. Battery had 70 discharges and it was starting to auto land prematurely at first it was at was landing at the first warning level then it got as bad as to auto land at 50%. I drained the battery completely until the led lights would no longer turn on charged back up and haven't seen the auto land issue yet after about 10 flights. However I do not fly with this battery past 10.8 volts that seems to be the sweet stop with these batteries. I have flown down to first battery warning without going into auto land. I actually did a stress test once the battery hit first warning at 25% I gave it full throttle and ascended up 50m to see what would happen. The volts started to sag but it did not auto land. The battery definitely is performing better after completely discharging it but I still don't trust it that is why I only fly to the 10.8 volt sweet spot. Hope this was helpful.
Got 3 batteries 8 months ago, 2 are now "puffy" and I'm afraid to fly them. Both of these have less than 30 charges, one has only 20. Does anyone fly with a battery that has the gray envelope puffed up so that if feel kind of like pressing in on an inflated balloon?
My batteries have been fine up until now. Now both of my batteries are all of a sudden faulty. Each only has 12-15 cycles. Every time I try to ascend, the battery meter on the iosd blinks and shows empty then auto lands, even when the battery is supposedly fully charged. What's worse is that the descent rate for the auto land is extremely fast and it slams my Phantom 2 into the ground at a high speed. I try to counter it with throttle up, but it doesn't react in time. I feel so cheated for having bought 2 of the expensive batteries that are now useless to me. They are well over a year old, so I guess I'm stuck with them with no hope of return or replacement. I have tried the discharge method and I'm still getting this behavior.
