I have a Phantom 3 Advanced (predates the 4K models) which hasn't flown all that much so it still has pretty new batteries all round. Last week I was charging the controller and one of the flight batteries normally, but some way through that process, the charger just decided to stop charging them. Now it refuses to charge anything.
I did a lot of web searching, but all I can find is numerous references to buggy software inside the flight batteries and ways around that, but not much about the charger. It gets pretty weird too. If I have the charger plugged just into the controller (which does nothing), turn on a flight battery and then connect it to the charger as well, the controller suddenly acts as if it is charging. The battery eventually turns itself off, though, and when it does this automatically, or if I do it manually, the controller stops charging too. It's as the charger is basically dead, but the whole system is so badly electrically designed that a powered-up, attached flight battery is able to push current "back down" the charging wire and into the controller; as if the charger wasn't charging the controller - the flight battery was.
Has anyone else seen this? Is there a way to reset the firmware or similar in the charger? I've bought hundreds of gadgets of the decades and I've never seen a charger quit like this before. Plenty of batteries, never the charger. It's a very expensive thing to replace too.
Thanks for all ideas - I'm practially at the point of pentagrams and chicken slaying now ;-)
(There's still nearly full charge in the controller, one flight battery near dead and one at about 60% - I can fly the aircraft on this OK, so the batteries don't seem to be faulty. The drone flies infrequently with less than 20 flights, but probably 30 or so charging cycles as I make sure I check the batteries now and again to prevent them fully discharging during log periods of inactivity.)
