Естественно, в прошивке батарейки останется старая ёмкость, но время полета всё-равно увеличится

The drone itself is already as light as possible, with ultra light plastic and everything. It is so light that you won’t be able to reduce much weight from it. And even if you take all the covers off, you won’t be able to reduce enough weight to make it worth it. Engineers at dji are not stupid, and if they could, they would make it even lighter.

Hello Zolly. Thank you for your interesting tests. I also have experience. I noticed that you drained your batteries to 6V for the test. The capacity is then 3.5Ah. In practice, the drone will turn off at 7V. The available capacity will therefore be less. Maybe that's why the original 2250mAh batteries are around 2000mAh. One more thing. Tell me what voltage did the external batteries discharge during levitation?
@ZollyD2 жыл бұрын
Yes, that is correct! :) When I disable the battery voltage monitoring system, the drone can do an additional 3-5 minutes, but after that it starts a rapid descent due to lack of power and if it is coming from high enough, not even the ground effect can save it from crashing. So that is why it is not included in this video. I think that is why DJI implemented the 7V limit as well, as the LiPo discharge curve breaks down at around that voltage sharp. Like this there is a bit margin for safe landing. The voltage on the the external cells was 7.15 V. (That is due to to the drop on the cables)
