It's raining drones, but just one specimen: DJI's Matrice 200 quadcopter

Re: Expensive brick

Given the model was released in 2017 that means the batteries have had ample time to be charged and discharged a fair few times, given they're commercial drones and not playthings, which probably means the batteries can't maintain peak output, so, although not depleted, output isn't high enough and that trips something (a resistor or capacitor is suddenly in the wrong state) and the whole system gets confused and goes down.

Kinda like my Note4 when I tried to open the camera, I'd have a 1 in 4 chance of it just shutting down, ah, those were the days, when you could easily replace a battery in a phone...
