Mini 2 batteries capacity

[Adam123]

Hello friends, I have read many posts on the subject without a solution, and that is why I am asking something very interesting, in short, after reading all the manuals and information about batteries, I am encountering a strange phenomenon since the drone was new and I received it with 7 batteries that went through an average of 30 charging cycles, I Doing a lot of hover tests, and let's assume that the drone is new plus calibration of everything possible, always while hovering with the battery at 100 percent, it gives me an estimated time of 24 minutes, the drone stands stable on top of its vision sensor, there is no wind, a temperature of 25 degrees The firmware is one before the last (6.200...1) I can't find any explanation why in the videos I've seen the estimated time is always 28-30 minutes, I noticed the accuracy problem in all versions of the flyapp software, thank you all, and again sorry if this has already been discussed and maybe i missed

Hello, my friend, nice to have.

Welcome to the forum!

Very hard to read that text font/color

I did a copy paste looks better for myself.

If a screwed up I can delete this post.

Hovering consumes battery at a faster rate than moving. If you look closely at the manual it states

"Maximum flight time was tested in an environment with no wind while flying at a consistent 10.5 mph( 17 kph) and the maximum flight speed was tested at sea level altitude with no wind. These values are for reference only"

after reading all the manuals and information about batteries,

I am not too sure how extensive your actual research was when you wrote, "after reading all the manuals and information about batteries" and you apparently missed a most salient point that @Yorkshire_Pud pointed out, ". . . These values are for reference only"

Perhaps the single most important factor affecting the flight time after the batteries is the impedance of all the electrical circuitry of the drone as in the resistance of the electricity to flow thorough out the circuit… The Wires, the solder joints, the motors, etc…

Impedance can be an important parameter during the manufacturing and servicing of DC motors. Unbalanced impedance can indicate problems with the motor core, windings, rotor, or rotor positioning. You do know that the only real quality test of the drones motors is: did it turn on, not internal impedance, not is it balanced, rotational resistance, etc… only that it turned on…

Then you never wrote about your research in the into the propellers, you only assume the drone is new, but how matched are all the propellers, did you examine each one, looking for deviations, did you check the weight of each propeller, you do realize that they are constructed in different plants, in different molds, with different mixtures of material? At 10,000 RPM, minor imperfections are not so "imperceptible" any more…

So many things to consider, so little time, and Opps, my time has run out… gotta go and perform an Insulation Resistance Test and Winding Resistance Test on the motors of my drone. Oh, did I forget to mention those test too…

So, go fly your drone, enjoy it while you can, and do not charge the batteries all night in the hope of charging them to 110% for an extra minute of flight time…

Hello friend, thanks for the long and informative answer, I meant to make it clear that I read all the material I could until I felt that the articles were repeating themselves, you may be surprised, but I did consider each propeller separately, I do the test in the basement without, until I noticed something that popped out of nowhere, when Note that there is an algorithm that rewrites the capacity according to its charging cycles, i.e. 60 cycles, the algorithm assumes that the battery is only 90 percent efficient and this is translated by the clock.

In addition, I took one battery that I said I would do an experiment on, I got to the point where the percentages are at 0, the clock, I also know the reality of being behind zero, but two minutes? It turned out that he hovers like this for 27 minutes

Leave it powered up with the battery at 0% with some cooling until it turns off on its own, then recharge. That'll recalibrate the measurement.

You wrote the Drone was new and it came with 7-batteries (I do not understand that…), but isn't some or all of it under warranty? If so, return it and get replacements that you can enjoy…

Greetings from Birmingham Alabama USA, welcome to the forum! We look forward to hearing from you!

Just gage your project time around the flight time indicated.

Welcome!

Thank you very much, dear friends, you are very respectful in your answers, and I said goodbye, I wrote that drone is new, I just bought it from someone who purchased 7 batteries, I did what they told me here, which is to leave the drone on until absolute zero so that there are extreme points, everything is new, I bought A double battery from eli Express which is 4150mah and is enough for 45 minutes, after a journey of 8530 meters one way I returned with 38 percent battery, of course in fcc.

It's not an easy situation, my country has been at war for a long time, you must have heard about the 7/10, almost a year ago, and there are still hostages in Gaza.
