Santa got me a P4 for Christmas, which I am just getting around to using because I've been recovering from an injury and surgery. Took it out yesterday and found that one of the batteries (fully charged) will not power up the drone. Back in Dec. before I actually got a chance to use it, I did all the firmware updates and had it ready to go. As a possible fix, I thought I would try to do the firmware update on this one battery again but apparently I deleted the firmware files on the sd card. Can someone tell me where I can get those files to put back on the card? I can't seem to find them on the DJI website. Or - give me other possible suggestions for my battery?
Thanks!
Thanks!
