I crashed my drone and had to change the left front arm, I'm versed in mending electronics and changed the arm and put the drone back together and turned it on. I was pleased to see the new arm connected and working fine, however as I was about to give the drone its test flight I was surprised by a "battery error" which wouldn't allow me to take-off, there was no battery information going to the drone however it had power and everything was working....I changed the battery with my other 3 batteries and the issue re-occured for all of them I took apart the drone to make sure the ribbon for the power supply was in place and the pins clean (which it was). I then tried to update it to the latest firmware but when it was to be uploaded to the drone it said it couldn't be because the battery wasn't over 50% (when it was fully charged and had all 4 green bars) i also tried to factory reset. but nothing I would appreciate some help.
