This battery came new and only showed 3 lights when 'fully' charged. DJI Pilot app showed it at 100%. After 3rd test flight in an attempt to reset it. This happened when I pressed it to test it out of the airframe, I wasn't trying to turn it on. I am returning it. The seller will make it right, just sharing the malfunction because I haven't seen it reported. Now, well, see video.
