Rockdweller, re your Amazon batteries , suggest repost on new/different thread to avoid confusion.
Back to topic, my fc40 camera is no longer giving any red solid or blinking lights when charging. I was using an ipad charger (2.1a) and an iphone charger (0.5a) indiscriminately, but now I am using a 0.7a charger from an old Samsung phone. When getting ready to fly, my green LED works fine, first fast blinking, and then telling me when I am booted (solid). Then slow green blinks when recording. But no red LED's when pluggged in to any USB outlet. I've tried my laptop, my desktop, as well as a Philips external device and the ipad and iphone chargers. BUT, the camera is still charging up well. When I plug in to charge, the camera goes hot for a while (charging), then turns cool after 20 to 40 minutes(charging complete). And it did warn me on screen in the app when the camera battery was low. Since then I have re-charged and recorded for over 20 minutes of video. SO, it still works fine, but I have no red LED indicator lights when charging. The quad did take a heavy hit once, where it took a while to get the camera working again, so I'm guessing it was either that incident or the high amps of the ipad charger that fried the red LED's.
