I am just using the same setup as this guy on this video I have used it for my Mavic Air batteries and now I am using it for the M2P packs. Its discharging the batteries to 3.8V per cell for storage. The settings can be changed if you wish to different values using a link cable and connecting this discharger to PC.
Flying with them is the easiest way to discharge the batteries. If you want to manually discharge the batteries for some reason, here are a few devices you could use:

No dont follow that practice of bringing it down to 8% that is just crazy and dont know why dji recommended that back in the day I know these have smart boards on them but I just don't see that being good for a lipo so I have never done it and never had a problem I always keep them at a storage charge when not in use 3.8v a cell is good....if you are on vacation or won't be around the lipos for a good while, you should have someone check on them as they do lose a charge sitting around...?
Well you are doing it the right way....good stuff??
If you base it on cell voltage alone, even after landing at 1%, all cells will still display 3.64V, which looks pretty good, but definitely requires a full charge thereafter to restore the battery.
Meh 3.64 is a little low....a good storage charge is 3.80 to 3.85v per cell. U also have to remember that when getting itnto the 3.6v range lipos are not stable and voltage will sag depending on what user is doing... And for an unexperienced new person things can get ugly fast.. ..and the reason u see that at 1% is because 1 % is not really 1%.....u picking up what im putting down?? All jokes aside dji does this on purpose because like i sd could be catastrophic if flying in sport mode and u are at 3.6v per cell... This is pretty smart actually on djis part probably saves them money and grief as far as warranty's etc .....because if that was the real percentage voltage would be around 3.3 to 3.5 v....so yea technically u can still fly at 2, 1, and even 0% .....buddy of mine made it almost a mile on 0% ......im just so used to treating lipos like traditional lipos and not smart lipos.....it has paid off for me
I can believe that with DJI batteries they hold a reserve .... 5% is not really 5% on a dji lipo..
Indeed! DJI has left significant power in the tank at their new 0%, which is probably the equivalent of the old 10% on the P3P's. I, myself, made it well over a mile on 0% on my M2. Truly forced descent did not take place until the lowest cell voltage dropped below 3.0V. Had I elevated sufficiently before reaching that voltage, I could have flown even further in a descending glide path forward, without running into the ground. Even after reaching 3.0V , there is at least another .5V to go, as in the FW battery parameter settings, the truly forced descent can be set as low as 2.5V. However the rate of voltage decline below 3.25V is radical! You can safely go to 0%, without damaging the battery, as long as you practice flying while fighting the descent with sufficient forward left stick, and know how to quickly hand catch! It's only for experienced pilots who need to push the flight time to max, without adding external batteries!
