dji says our p2v 5200mah batts are good for 300+ charge cycles.
Imperative data from actual users say it is more like 20-50 cycles, with a few going 100+ but none reaching the rated 300 min spec.
Since dji will not share REAL battery data with us, let us compile it ourselves!
I propose that we each post here the full battery data assistance gives us - anytime we run the app and have time to post it here. With this data, we can build our own dji curves for these batteries.
With this compiled data, we can state for sure what these batteries require as far as charge and discharge rates. This info alone should allow each of us to double our cycles.
For instance, today, dji says "discharge every 20 cycles to 8%." This goes against all known lipo design data. Others are reporting that 80% discharge according to dji assistance is 3.70 volts - again, not very normal for this chemical make up battery, but true according to dji.
I will post first from today's flight and 2nd battery charged a few days ago but not used:
