    I know it's only been a few days but would like to ask you guys.

    How many of you guys updated to the newest firmware (FW 1.5.0.3)?
    If you have, do you think this fixed the recent battery problem?
    Dropping the voltage 80% -7% or whatever?

    I have updated mine and fully charged from around 60% to 100%.
    It seemed taking a lot longer than usual.
    Charged two batts. One TB47 and One TB 48.

    TB47 took about a little less than an hour (from 60%) and TB48 took about an hour and 10 mins(from 60%).

    What are your experiences?
    Do you guys think it has been fixed?

    Good to see you around these parts again!

    I updated the other day, but haven't had a chance to test yet. From the anecdotal responses that I've seen, it does appear that this issue has been resolved. I'm hoping so.

    What's up Ascender. Long time no talk. :)
    Yea, I really hope so. After hearing all these horrible stories from others, I could not fly over water anymore.

    I tested two batts (TB47, TB48). They seemed fine.
    I never had any problems before. So could not tell the difference though.

    OK after the latest FW update (1.5.03), I have tested 4 batts so far. 2 TB28, 2 TB47.

    Note that I’ve never had batt problems in the past.
    I’ve never flown with partially charged batts either.

    1 TB47 and 1 TB48 were tested a couple days ago.
    They both were fully charged on the same day I tested.
    Started from 100% to 40%. No problem.

    I tested another 1 TB47 & 1 TB48 today (12/11/15)
    They were stored at 68% (TB47) & 57%(TB48) for a few days (at least 3 days)
    Since these two batts have been stored for days and weren't fully charged, I mostly hovered or flew within 30 ft and 3-4 ft above the ground.
    I flew till 5% as I needed to deep cycle the batts.
    No sudden voltage drop or whatsoever.

    I would still not fly with partially charged batts but it’s good to know my batts are ok with this condition. I wish I had a batt that is not updated to compare but I don’t.

    Hope to see more feedbacks from other pilots!

    I think further testing and different user results need to be posted up before we can say for sure but early signs are encouraging.
    A proper test would be :

    Set you batteries self discharge to something like 2 days.
    Fully charge a battery and then fly it down to circa 60%.
    Remove the battery and leave it totally undisturbed (which means NOT pressing the battery button) for around four days. This would mean the battery has gone two days into its self discharge mode.
    Take the battery after four days, load it in the Inspire and fly it.
    A few test like this and we can (hopefully) say the problem is solved.

    The two batts I tested today was almost same as you suggested. I flew till 60% or 70% and stored (discharge set at 2days) for at least 4 days.
    In between I updated the FW and tested 2 batts today.

    But I totally agree that we need to see more results from other pilots.

    Thanks for that.
    We need to see results for batteries that have entered self discharge as well as ones that have mearly sat and not entered that mode.
    Like you,I have NEVER suffered the issue nor have I been able to reproduce it in testing so I am relying on people who have regularly experienced this anomoly to test this one out and make sure they have confidence in their partially discharged packs now. :)

    Yep, I agree.
    Hope to see more people especially who had bad experience participate. :)
