hi everyone, im new to the forum.

I've just started having a issue with my dji f450/naza m lite ( no gps)  

it recently started: i would start her up and she would lift of the floor at almost full throttle but just hover 3 or 4 inches of the floor and the led indicator would flash red rapidly like if the battery was low but it was fully charged. i took it to my local hobby shop and they said the battery was fine soo it could be a " software issue" I've tried going through the flight control software on my pc but nothing wrong......  its really frustrating that i can't use my baby

my setup as follows :
dji f450 frame
dji e300 2122/920kv propulsion
tarot 2axis gimbal
hyperion 3s 5000 mah 25c 11.1v lipo
spektrum dx5e transmitter
spektrum AR400 receiver
9 4x4.3 carbon fiber props
and finally some dji legs

Have you checked your gain settings? Flashing "RED" can also indicate other errors, not just "low battery." I would suggest checking your gain setting first. You did mention in your post that you had gone through the flight control software on your PC but you did not mention the gains which is why I bring that up. Also did you calibrate the compass? Was there any issue with the calibration?

PMU failure does sound like a cause, is there any way to fix this issue or will i need to find this part or get a entire naza

BTW, did you try another battery? How many time you use it? A battery failure is also possible.
