Sorry, but I don't agree with this. I completely agree that the battery was bad. It had a bad cell. The OP deserves a replacement battery.
What I don't agree with is that, "even with a 100% charge, this still would have happened..."
I believe that if he had followed his manuals instructions and if he had followed his battery safety guidelines, he would not have lost his Phantom in a crash.
These aircrafts are programmed to issue warnings when there are obvious battery problems. They are programmed to auto-land when a battery cell drops below 3.3 volts. In this case, the aircraft did not auto-land when a battery cell dropped below 3.3 volts. Why?
It's obvious to me that the reason is because the OP decided to launch with a battery which was not fully charged, which is contrary to what is stated in the owner's manual, and it's contrary to what is stated in the battery safety guidelines. He either didn't bother to read these documents, or he didn't read them comprehensively, or he deliberately decided not to follow the advice.
One can argue that the AC should have auto-landed. One can argue that the FW needs to be fixed so that the AC auto-lands when a cell reaches critical level regardless of whether the pilot follows DJI's advice not to launch with a partially charged battery. Still - we've seen countless examples of drops from the sky - and one of the common denominators is a launch with a partially charged battery. There is something about a partially charged battery which confuses the software and puts the battery into a position to shut itself off mid-flight without warning. We've seen it over and over. It's extremely rare for it to happen with a fully charged battery. I'm not sure it has ever happened.
Meanwhile DJI specifically states that the pilot must launch with a fully charged battery.
I am happy the OP is apparently getting a new or fixed Phantom, but maybe he could be just a little bit more humble in his attitude towards DJI, considering the obvious fact that his own deliberate actions are - at least indirectly - what caused the loss of his Phantom. |
