So the video doesn't actually contain many errors, but in fact simply highlights issues that you disagree with, including it seems, being acceptable to fly with swollen batteries that are undergoing catestrophic internal degradation in order for them to be swelling...?
Yes, TBH it's easy to just disconnect the hub, with batteries inside, then put the whole hub in the carry bag and off you go. I do that as I can connect the hub to the car phone charger if I'm driving out somewhere, but you're right, unsure if 3 discharging batteries together would be getting a little too warm......
Mine aren't. After a flight I charged the battery in the drone via USB-C, and 3 days later it was still at 95% charge.
Just turn batteries around and put them back in that's what I do.Appreciate the heads up Ian, this really needs addressing by DJI.
Just knocked up a temporary cover to prevent the battery engaging the contacts in the hub - it simply hinges away when you need to charge but blocks during storage.
I stand by my original statements. Your errors are a gross misrepresentation of the situation. I have been flying DJI drones since 2016 and have always kept all my batteries fully charged, unless they are deliberately in storage. I have never had a battery failure, and all my original batteries are still in service, despite my "abuse" of them. I don't own drones to prolong the life of the batteries. I own them to fly them, whenever the opportunity presents itself, which requires fully charged batteries. The only risk from obviously swollen batteries is potential detachment in flight. I don't fly with obviously swollen batteries. I use them for FW updates, preflight setup, and other ground based use, and swap out with an unswollen battery prior to launch. Out of 50 batteries, only 3 have swollen under this "abuse." Auto-discharging and recharging your batteries also unnecessarily reduces the life of the battery, as the expected life is 200 full charges, and every auto discharge to 72% uses up almost a third of one those 200 full charge cycles. User control over the battery discharge cycle already currently exists. Don't store the batteries in the hub or the drone if you want them to auto-discharge. Simple. Yet, you want to impose what you unilaterally believe to be best, upon all other Mini 2 owners, by demanding a DJI FW update to preclude user control! Not good!
I've not demanded anything; the industry-standard view is that swelling batteries are a sign of internal damage that can cause failure in mid-flight. Your view seems to be that it's only an issue if you can't stuff the swollen battery in the drone.
More errors. "Industry-standard view is that swelling batteries are a sign of Internal damage that can cause a failure in mid-flight" Exaggerate much? A hypothetically swollen Mini 2 battery would not fit inside the drone. It is not internal damage, but only the mild physical deformation of a Lipo battery that causes any potential electrical disconnection in flight from swelling. Swollen batteries do not fail. They still maintain an electrical charge and perform just as well as an undeformed battery, aside from impact of the physical deformation. When used as supplemental external batteries, swollen LiPo batteries perform just as well as unswollen batteries.
All due respect, I personally left 2 fully charged Mini 2 batteries in the hub and the third fully charged in the drone for 2 months in the bag in my car. After reading this I checked them. The two in the hub displayed only one remaining light of 4, while the one in the drone displayed only two lights of 4. Clearly, they are still discharging, even if only slowly over time, like any other Lipo, that loses up to 1% per day.
