Flew my FPV for the first time today.  Noticed the information on the screen on my headset is behind.  For example, while I was flying my screen indicated I was taking off.  Prior to that while it was taking off it was telling me how to start the rotors.  Biggest kicker is that it indicated I had 45% battery life left but suddenly went into RTH mode and landed.  When I looked at the LEDs on the battery only one was lit indicating it was likely closer to 15 to 20% than 45%.  Any advice besides returning it?
