    I've been away for awhile due in part to our winter.

    Did I read somewhere that DJI has introduced P2 batteries that automatically discharge themselves and.

    If so:

    - do they work well in properly discharging?
    - how do you tell the difference between the old and new batteries?

    Thank you. So it's a firmware update to my current batteries, not new batteries?

    They do start to auto discharge after 10 days down to 50 %

    Thank you, Dirk. All my batteries are the older style. Can they be updated to incorporate the discharge feature?

    Not sure that v2.6 battery update is working. It was working when the v3.6 first came out and I updated all my batteries both new and old but that's been awhile. The new style info contacts on the batteries came out before the v2.6 upgrade. So all you can do is try an see if it works.

    The battery discharge feature starts to work within 48 hours not 10 days. It also takes a few days once the discharge starts to reach 50% for storage.

    Not on mine, I updated all three to that newer software last autumn but shortly afterwards they pulled it and don't think it has been available since.
    They start to discharge after 10 days and it takes about 48 hours to do it.
    My oldest battery is the round pin type and it works just the same on that one.

    Maybe in your part of the moors it takes 10 days before your batteries start to discharge :eek: but not in the rest of the world. :lol:

    I notice on my updated battery that after 10 days the battery was at 75% and it took almost a month to reach 50%!
    If you likely not to use a battery again for a while could you partly charge a battrey to get close to 50% or would you need to fully charge the battery and just let do its thing? Pity that DJI could not have had a storage option on their charger!

    I have 3 older V1.0 batteries (model number 733496).
    1 have 1 newer V2.0 battery (model number PH2-5200mAh). This comes with a bright orange warning stating it wont work on older firmwares.
    Both have the square pins.

    Have you fully charged the new battery and plugged it into unit and does everything lightup? Or have you even tried it because of the warning lable?

    Works fine. My firmware is 3+. I've had about 5 flights on it. I hope the V2 batteries address all the known issues.

    As I have said before all my batteries new and old were bought before v3.6 was available and I was able upgrade each batteries firmware. Due to the cold weather I haven't tried the older to see if they will still fly to the first warning or not. Before upgrading the two oldest batteries were autolanding 40 - 45% and after upgrading the first warnings were 25% which showed the firmware did work. So I'll just have to wait for warmer weather to test fly those two.

    Unfortunately, the battery firmware upgrade itself no longer seems to be available.

    Perhaps I shouldn't say that it's "unfortunate" that it's unavailable. Considering their record of questionable releases, if DJI doesn't think it's worthy of release then we must be better off without it.

    I used it when it was available and it worked for me. Why they pulled it who knows.

    Obviously they naturally drop slightly, but after ten days the firmware on my batteries [you can't get now] starts to discharge them quite steadily.
    After about 24 hours the fourth LED is flashing. After 2 or 3 days two are lit and third is flashing - then it stops discharging.
    You can check the condition without starting and the countdown is not affected.
    There is no discharging initiated after 48 hours of non-use.
