    Mavic Air 2 44:20 min / 19.5km battery mod

    I did not invest in the end in the programmer tool and the software. Vmax would be the same (4.4V), I measured 7350mAh capacity with an external load, the rest I don't know.

    mode_gentle_cfg_vert_vel_up

    Yes, also the annoying beeping can be disabled. Search for “battery” in the parameters and switch “action” variable to 0. I don’t have the drone with me so I can’t name the exact variable but it will be self explanatory. For the warning and the beep look for a variable which is 15 by default...

    mode_gentle_cfg_vert_vel_up

    You’re right, sorry. To choose gentle mode (instead of tripod mode) when switching left: fswitch_selection|g_config.control.control_mode[0] to 6 All parameters that need to be changed: mode_gentle_cfg_vert_vel_up to 10 mode_gentle_cfg_vert_vel_down to -10 mode_gentle_cfg_tors_gyro_range to...

    mode_gentle_cfg_vert_vel_up

    As @prz3mk0 said, you "enter" gentle mode, also called tripod mode or cinema mode, by sliding the mode selector to the very left on the controller. I confirm that my Air2 can climb and descend with 10m/s, so there is no power or hardware limitation preventing it, only software. The default 4m/s...

    Farmer shoots at my MA2 drone

    Many thanks for all the answers. I find it difficult to accept that one with a gun can make the law. Of course it’s the “smart” way to leave this guy alone, but doing that is going along the rule of the wild west, rather than a modern state of law. Next time the farmer will shoot at bikers...

    Farmer shoots at my MA2 drone

    Thank you for both answers. It was loud boom-boom, similar to an exhaust pipe backfiring. I'll fly at 120m (max allowed).

    Farmer shoots at my MA2 drone

    Yesterday I was flying my drone, crossing a field at 30m altitude about 400m from my home point. I heard one gunshot coming from the drone's location, then another 4 or 5 within the next 30 seconds. After the first shot, I realized they must be shooting at my drone, ascended to 80m and got the...

    Mavic Air 2 44:20 min / 19.5km battery mod

    Thank you Lee. I did order the CP2112, it's on its way from China. I contacted TRB to send in my battery (France to Slovakia), reprogram it and send back, but the two-way shipping and reprogramming cost is similar to the Ev2400 clone + TRB license. Also, in theory the post doesn't allow...

    mode_gentle_cfg_vert_vel_up

    Don't worry to push it to 10 m/s. The firmware will not allow to overload the motors, and will just display a "Max motor load reached. Fly with caution" warning if you push too hard. This protection is there for non-hack scenarios like when you try to fly against strong wind. My experience is...

    Descent automatically slows to less than 1 mph

    I have the exact same issue, it started in June 2022 as well. Something DJI did messed this up for everyone. I've sent back the drone for DJI for repair. I did not update the firmware prior to the issue appearing, albeit I might have updated the Flysafe database. (I looked at the log and just...

    Mavic Air 2 44:20 min / 19.5km battery mod

    I did a DIY battery mod experiment. I first ordered 3 of these cells from Aliexpress (credit to @lee82gx for the advice!). Then I opened a stock battery, and after equalizing the voltages, soldered them parallel: Apologies for the makeshift case, I will make a nicer one once the...

    Christmas test: Mavic Air 2 weight vs. consumption chart

    Maiden flight: hovered indoors for 41:37. (Stock battery: around 30 minutes). Will fly outdoors tomorrow. It seems that there is a certain self-learning of the BMS, the indicated capacity is increasing by 100mAh after each charge cycle. I will report more details later!

    Christmas test: Mavic Air 2 weight vs. consumption chart

    Assembled a DIY pack, will make it nicer if works. Not for the faint hearted - my small spot welder doesn't weld to the steel cathode, so I needed to solder, and there are 100 different ways to accidentally short out something while doing this. I have created a spark when a balance cable...

    Christmas test: Mavic Air 2 weight vs. consumption chart

    Cells arrived from China, up for some balancing, soldering and testing, will teport back!
