Hey guys, So i just needed about two full weeks with my new P4 to crash into a flagpole (the only one within a hundred miles) The shell is slightly damaged, but everything is where it should be. The last flights has given me error messages like; Battery error, voltage critically low It is the same story even if i swap with a new original battery. If you have any suggestions as to what i should try, please tell. I dont mind popping the thing open to check any wiring or continuity, or what you might think of. The error messages pops up randomly, even with 90% + capacity. Thanks!
