Hello Hello from Germany. I am Markus and almost 51 years old.

Since about May 2017, I occasionally fly the Mavic Pro (alone, with my girlfriend or friends) in Schleswig-Holstein near Denmark. For this we travel mostly with the bike to locations in the immediate vicinity of our home. Not quite 50 flights have been completed so far, but it is always fun to go on tour with this great aircraft.

For me, the Mavic Pro has proven to be an extremely reliable aircraft because there were no critical events throughout the time of use.

Unexpectedly, I leave at this point all the experience gained with the DJI-Go App, as well as all in the past taken updates.

Even the five original batteries (1 + 2 Fly more + 2 Extra) have so far lost only an average of 2.5 percent of their original capacity after around 16 months. All capacity measurements were done with equipment from ISDT and a suitable Mavic adapter cable.

Incidentally, I found out that the intelligent batteries of the Mavic also accept extremely low charging currents from about 0.5 amps.

However, the charge and discharge currents were constant at 0.26C / 0.52C (1A / 2A) in the consecutive tests, which of course does not meet the real requirements. In flight operations, the requirements are significantly higher and fluctuating greatly.

Anyway, no battery is bloated so far, and still the average flight times are pretty good at 21 minutes.

Maybe someone is interested in my personal handling of the batteries, so I explain briefly below:
- The batteries are charged at least 12 hours before the scheduled flight, and fully recharged at the latest 6 hours after the flight.
- I do not leave any batteries discharged for the stated period of time, and the automatic discharge down to storage voltage (3S / 11.4V) always starts after 24 hours.

- I never charge hot and extremely cold batteries.

- Stored batteries are never charged above 1C (3.8A), at best, they are filled again at 0.26C (1A), because I hope it helps the balancing.

- The usual storage temperature of the batteries is here at about 22 degrees Celsius, and I do not use them at temperatures below 10 degrees Celsius.

- I use complete charge cycles if possible, although this is not mandatory for lithium batteries (LiHv).

- I almost never use the Mavic's sport-flying mode, as it stresses these small batteries extremely.

- I do not fly in very windy situations.

In September this year, I got two new Powerextra batteries. I received these two replicas for the price of an original DJI battery. Due to the price, I dropped any concerns, and so far after two flights per battery I am pleasantly surprised. Both batteries had an initial capacity of about 3930mAh.

So, that was it for now...Enjoy flying everybody...

I don't use them, but I know a lot of people like them and have good experiences using them. They are apparently made by the same company that manufactures DJI's batteries (according to the Internets).

BTW, you have some nice designs on Thingiverse. Thanks for sharing them.

Hello,
It is a pleasure to welcome you to the Mavic Pilots forum.
I hope that you will be able to use the forum to further your safety knowledge and for the exchange of innovative ideas and as a resource for current developments in Mavic quadcopter’s.
Enjoy the forum! Thumbswayup

My Mavic flies so far very reliable with two batteries from Powerextra. And the achievable flight times are felt even a bit higher. I think there are not so many factories producing such LiHv batteries anyway. Much more, I suspect that after the lapse of a certain period almost all battery replicas come from exactly the same Chinese plants that produce directly for DJI. Currently you can watch on eBay as more and more brandless batteries are offered for the MavicPro. The names of the providers are very imaginatively differentiated, but somehow seem to have the same origin.

However, Powerextra offers a very good alternative to the original DJI batteries. As a temporary Amazon offer I got here in Germany at short intervals two pieces for the price of an original DJI battery. I trust these replicas, because they actually have a high quality overall, and are easily recognized by the Mavic with all key data.

In addition, I have determined the available capacity by means of measurements. For both batteries, the capacity is initially slightly above 3900mAh. However, the tests were carried out with constant discharge currents of 1 and 2 amperes. There were no abnormalities and no significant cell-voltage differences. The balancing is excellent. In practice, the requirements are of course much higher, and not constant. Nevertheless, I would like to share with you the findings.
 
And yes ... Anyone who owns a 3D printer and actively uses it, for example, to produce accessories for quadrocopters may like to look over at Thingiverse and visit me there. I have a few designs for the MavicPro (first generation) which are of course free. I'm glad if you try something out of it and maybe give a short feedback.

Many thanks to all who took the time for a welcome greeting to me. I have received many motivational words and a good mood. I will try to give all that and more back.
