I'm excited. I have successfully charged the battery, assembled the phantom, performed the calibration "dance", got rid of the ubiquitous error 27, and upgraded all of the firmware/software I could find. After all the pre-launch messing around which, I hope, is going to give me a green light to launch, I decided to top off the battery before I go outside again. This has me wondering...Do these batteries benefit from being drained before recharging or does it make any difference to them? I don't want to do anything that would shorten a battery's life and just want to adopt best practices all around including battery charging. Thanks in advance.
