Hiya, took my drone out today and got a message saying invalid battery.  I decided to carry on flying and everything was fine and dandy. When I went To charge the battery the first green light is flashing but that's it. Won't go up the scale like usual.  

Any ideas please
Thanks

Ok panic over I think. I must of drained it so much that it took longer than usual to start going up the scale. Phew!!!

I get the "invalid battery - please fly carefully" warning occasionally.  only for a couple of seconds, then it goes back to normal.  It hasn't caused a problem (yet) other than a bit of puckering

If you have not had a bit of puckering in your flying career then you are doing it wrong
