I just bought my DJI Fpv and i was going to make sure my batteries were fully charged for my first flight and I realized one of them wasn't blinking any led to show the battery percentage. So I connected it to the charging hub of the fly more kit and I realized that a Red Led turns on. Anyone knows how to solve this problem?

Hello there sants1915. I am sorry to read and to know that you are having this issue with your new DJI FPV. Kindly please post a short sample video showing the said issue for us to see and can assist you further? Thank you.

A few folks have been raising issues with the initial battery shipped with the FPV combo kits (myself included).  The initial battery in the kit doesn't want to charge.  I purchased the "fly more" kit last night (+2 batteries and charging 'stick/hub') and the original battery is the only one failing to charge - and the charging hub goes RED once I plug in the problem-child.  So it seems like a rash of battery issues on those initial batteries.
