I have three batteries that came with my Mavic 2 Pro brand new, day of launch, straight from DJI, China. I have many other tech items I use, including a Mavic Pro and an Osmo Pocket and various action cams, etc, so flying the Mavic 2 a lot hasn't been a priority. These batteries have had very little use. I charge them once they hit 1/4 to 1/2 capacity to keep them fresh, not allowing them to completely discharge. Until recently they have all seemed fine as far as the lights on the battery are concerned; charging up they are flashing consistently in sequence as they should, when charged and flashing stops they show four lights for "fully charged"... but when I put one of the batteries into the drone and power it on (it powers on but the motors will not start and the blades will NOT turn), there is immediately a low battery warning that comes on screen and a "Return to home immediately" warning as well, saying there is not much battery life left. (See photos... and NO, the beer in the background was not consumed prior to trying to get this battery to work!)
First thing I see upon startup of drone
This is what worries me: "battery Signal Error"
Going into the battery on the Go 4 app, there is NO info showing up for the battery; the cells are all empty, number of times charged, etc all show "N/A" for info, as though the battery is not connecting, even though the drone IS RUNNING.
Battery in question shows nothing for info
The app clearly shows all is well with the other batteries
Good batteries show up fine
and there is more than enough juice to run the camera/gimbal, etc, it's just not getting that info to the drone's brain.
The lights on the battery's switch are working fine, flash in sequence while charging, go out when charging is complete and come on when pressed to show a full charge, also sequencing through the startup of the battery, but when the app info comes on screen, there is no battery info getting into the drone's computer.
Light works, sequences when charging, starts drone but won't power motors on
I have an email in to DJI support, but was just wondering if anyone else had this problem and was informed of a possible easy fix, hard-reset sequence of button pushes, etc they could share.
Thanks in advance.
