I think you guys (Msinger and Nigel) are more in agreement than you think. There are people reporting that DJI batteries do effectively discharge beyond 65%, but this seems to happen in 3 separate phases:
- first phase is a fast, "active" discharge, via internal resistor (battery gets warm), that starts after the number of days set in DJI GO and brings the charge down to 65% in about 2 days
- second phase is a slow discharge, not sure if obtained intentionally via internal resistor at lower current or simply because of the current pulled by the "intelligent" circuitry, until about 50%
- third phase is hibernation, with zero (or near-zero) current drain, to prevent over-discharge in case of long-term storage
Whether this is true, I don't know...
but it definitely makes sense, and actually explains some of the wording in the battery manual.
