@Michael-Hatton Yes, you need to have a separate battery charger. I'll see if I can get a recommendation from the team on a good charger to use. I use a Hota D6 Pro, personally.
@Michael-Hatton When you arm the drone it is in flight mode and the motors start to spin. It's that spinning of the motors that you don't want while plugged into a power supply. Only use your battery to actually spin the motors and fly.
