    Mavic air Battery

    Yes! It could be so as the only remaining, working battery is one purchased about 6 months after purchasing the original MA package with 3 batteries.

    Mavic air Battery

    I have opened up the other 2 dud-batteries and they all read approximately the same as the first as posted earlier above: Cell 1: 3.7 v Cell 2: 1.9v Cell 3: 0.01v

    Mavic air Battery

    Thanks Detrilago and everybody else who offered advice. Hacking the firmware is beyond the scope of my capabilities, especially on a chip of that tiny size so I guess that 3 x new batteries are required and, in future, I'll charge up once every 2 months! But because the batteries are useless...

    Mavic air Battery

    Thinking about it, remember that this only occurred after the batteries lay dormant for several months so it seems unlikely that any cell is damaged just that the charge controller needs waking up?

    Mavic air Battery

    Thanks for your assistance John32. I'm not familiar with a lipo charger. I guess from your suggestions that the DJI uses LiPo so, is the DJI charger then not a LiPo charger from which I could jumper across some charge to those errant batteries? I do understand that they need to be charged...

    Mavic air Battery

    I opened up one of my 3 dead batteries and measured the 3 cells, which presumably are supposed to read 4+ volts when fully charged: Cell 1: 3.7 v Cell 2: 1.9v Cell 3: 0.01v Across all 3 cells: 5.6v (Unsurprisingly!) Because it will not switch-on when the On-button is held down, there is...

    Mavic air Battery

    I have the same problem with 3 out of 4 batteries after having been unused for several months, and long out of warranty. No lights on the battery and when connected to the charger, the green led goes on for a few seconds, then goes red for about 10 and then the cycle repeats. Surely there is a...

    Mavic Air Battery won't charge. Need help please.

    For a second time now, I have a battery that, after a month or two of non-use, refuses to charge. The charger blinks green three times then switches to red. When I press the battery switch, nothing happens at all. I have 4 batteries and they have been recharged in the region of 50 times each and...

    Buying used Mavic Air

    I've owned an Air since Dec 2017 and despite a few minor crashes during my experimental phase, (not fully understanding RTH and pushing the wrong buttons at the wrong time etc.) it has come through unscathed and it still works extremely well so, if buying used, I guess it depends upon its...

    18.2 KM Here is my newest test range Recorded

    Personally, I admire Johnphams spirit of adventure and risk-taking although I certainly wouldn't attempt any records, risk losing my precious drone and possibly injuring a person due to a crash. BUT, I also bet that all you critics are now happy to know the POSSIBLE range.......... 18.2...

    Question ! What do you start up First ? The Drone or the Controller ?

    RC then Mavic Air works for me every time. Using an Android mobile, the DJI app opens automatically after a short while once the RC is turned on and I allow "Connection in USB mode".
