I have an Inspire 2 and it have over 200 hours of flight time. Lat year around this time we had a battery issue where the batteries would drop to zero in flight. In talking to DJI it seems like you can only do 90-100 charge cycles on them. I am seeing the same issue this year. The odd thing is that the battery that drops to zero seems to always be on the same side of the drone and a different battery in the pair each time. When looking at the drone from behind it is always the battery on the left. I think that is battery two. The Volts always still read the same as the other battery and the cells all seem to be ok. Could this be a drone issue? We did clean all the leads but the issue is still there. Has anyone else seen this. I am working on getting a second drone to see if the issue still happens on that drone. Any information that can be provided will help.
