Today I got a new battery in the mail and wanted before charging it I remember that the battery was OFF, I then went out to dinner and knowing it was a smart charger it would just cut off the power once finished. When I returned home (About an hour later) the battery was still charging but almost finished. It then fished up but all four lights were solid green. I thought it was strange and I guess the battery was somehow turned on during charging..might've been someone in the house but regardless... does it hurt the mavic pro battery if it was "on" during charging? I know they have attachments to use it as a power bank but I thought it was strange..
