Hi all!
First, thanks to Ian for sharing this information.
Flying a
M2Z for 1.5 years I was used to the fact that the batteries discharge automatically to 60-70 % after some days (configure this in the app).
Having bought a
Mini 2 some month ago I was irritated that their batteries kept their charge. I read somewhere in a forum that
Mini 2 batteries won't discharge automatically and was "pleased". Yes, LiPo's should be stored at 2/3 charge to be stable so I wasn't really pleased at all.
Having the fly more package I stored the 3 batteries in the charger but put the charger in a LiPo bag which was designed for keeping 3 Mavic Air batteries but fits perfect for the whole
Mini 2 charger after having removed the inner separations of the bag.
Reading the different opinions in this thread I took one battery out of the charger for 48 hours and put all 3 of them in the
Mini 2 to get the exact charge using the app afterwards.
The one out of the charger had 94%, the two stored in the charger had 93 resp. 94 %. Firmware is up to date, all batteries were fully charged aprox. 10 days ago.
So it seems not all of the
Mini 2 batteries discharge like stated in the manual if they are stored outside the charger or drone. Or perhaps they need more time to do this. I will try to monitor this but it's something I didn't expect from DJI products.
I will keep them in the charger but separate the contacts with some removable isolation tape and put the charger in the LiPo bag. But I won't charge them after flying but store them more or less empty if they don't discharge automatically in the future.
