Hi all, I've been affected by the dreaded "no signal" issue for awhile now and have made adjustments to ease my issue but have recently have been thinking about it. I've been keeping a mental note as to my batteries performance and have found my original battery is the one I see predominantly has the issue, very interesting. This has nothing to do with lastest firmware at all. I will contact DJI support and will give feedback. Very interesting if batteries can have an issue that may affect it.
