I can go PayPal.....also good news, after some research, I wanted to share with the forum, that I am recovering the cell info on the batteries. Got two out of three done so far.....It seems that when you upgrade the firmware to 2.0.12.bin, the optical flow and batteries also need to have the firmware updated. Easy fix: remove the microSD card after drone firmware update....you will see that it added a .old to the file. Delete the .old by just renaming the file 2.0.12.bin, reinsert and repower controller and drone and it will update the Optical Flow and Battery. You need to repeat this step for each battery...... I will post pictures soon!
