I got the Mini 3 Pro and the Fly More kit. When I pull out a battery from the three battery charger and use it, I'm not sure what to do when I am done with that battery. If I stick it back in the charger, it looks like all the batteries will be charged. The others might be headed to storage mode and I may not want to disturb that for now, but I hate to have to pull them out and leave just the one in for charging. Does anyone have a strategy for battery care?
