Finally got the drone and controller to work on computer and with each other. Noticed that battery was blinking with 2 bars left. Charged it and now when I install it in the drone and turn it on the 4 green lights come on as well as red but go out in a few seconds. There is no beeping as well. And yes I am correctly turning the battery on with 1 short and 1 long press. Out of the drone the lights come on and stay on for a few minutes. Only have 1 battery right now so not an option to use a different battery. Anybody got an idea what happened? Was so close to finally getting it to fly!!
