Was wondering what % do you charge the MP RC? With the Phantoms the RC seems to last a lot longer so I usually wait until it goes down to first or second light. I've noticed that my Mavic controller seems to go down quicker. I went for a flight a few days ago and the RC is at about 80%... Should I wait for it to go down more, or is it fine to just charge it to full. I'm old school and have been conditioned to always wait until batteries are low before charging. Does it even matter with MP's RC?
