Hey guys, I just ordered my first DJI phamtom package. It comes with FPV and also zenmuse! I'm really excited, going to be outdoor next week and planning to give it a spin. However one question, how do charge multiple batteries at once? Or how long does it charge takes? I bought 3 batteries to go with it. So I should have some decent fly time. But at the end of each day, I want to be able to charge all 3 at the same time before I sleep. Is this a good practise?
