    Hey guys!

    I just un-boxed my new Phantom 2 zenmuse.
    The battery that was inside is not responding to my fist short press, and obviously, not to the two second that should follow.

    I thought maybe it got draind during the time passed manufacturing, so i plugged it to the chrager.
    the charger light remains green and the battery LED's keep being off..

    Did I do anything wrong? i have not done anything else yet, not assembling the props, never connected to the computer.

    what should i do?


    Thanks.

    Sounds like a bad battery, if you bought online, contact seller, maybe they will replace it.

    If it's been stored totally flat then it's prob knackered, i would contact the seller in the first instance and see what he wants to do

    Thanks guys, i've contacted dji support and they asked me to film a video of me explaining the issue.
    And if ill provide strong enough evidence, they will send me a new one.

    that sucks, it will probably take a while..

    I agree with J Dot. The battery probably depleted and killed itself while the unit was on the shelf for months waiting to be purchased.

    Just get yourself a second battery while you wait for the original to be replaced. ;)

    I've just had this exact problem on a battery that had been unused for nearly a year. As it was out of warranty, I disassembled it to check the voltage. All was good at just under 11 volts. Then I noticed a solder pad marked "RES" on the circuit board. Connecting this to the "GND" pad for 5 seconds reset the battery monitoring system, and everything came back to life. The system didn't know the actual battery charge, so I charged it a few times (until the battery had 4 LED's - it would stop charging early so that's why I kept going), and all is good. The charge count has also been reset to 1!

    Man,
    Useful info, as I have 17 batteries ( p2 ) 4 are bad, going to try this trick on the bad ones ( as I have nothing to loose ) I've been using hem with my elephantom, as it does not require a load, so battery will discharge completely ( not 70% straight to 7% gimmick! )
    I'll let you know,
    Thanks for sharing!
    A+

    I took a nice pix of my P2V3+ test battery circuit board to post here, but it disappeared. grher! Anyway, mine appears to have no such point marked RES. I have OVP, UVP, GND, VCC...

    I checked the bottom of the board also...

    Could you post a picture showing where this RES is on yours please?

    This could open up a lot of possibilities. For instance, I replaced the bad cells in my test battery, it is now like new, but without a reset it still says bad cell in dji applications.

    Thanks.
