My P3P gave me the critical voltage message on a battery that had about 64% charge. Cells were all in the green range. Fortunately I was flying it in my living room and landed safely. I recharged that battery and flew successfully outside to 50% I am not on the current remote firmware, as this causes the video down link to tablet to display garbled, but back one version works fine, and now this. This is a firmware issue folks...
I had dji on live chat after the garbled video issue and they told me to send the drone in. I laughed at that, but obviously something is wrong between hardware/firmware that dji physically needs the drone to fix and I would say both problems are related.
