This is why I like prototyping with Arduinos - you'll 99% likeley get away with plugging an 11.1V (or 12-13V fresh off the charge) battery into any of the pins on an Arduino. You'll be looking for another RasPi if you made _that_ mistake...

In this case, it wasn't the voltage, which had been brought down to 5v by the motor controller, it was the 160+amps. Not milliamps, amps (3300 mah, 50c battery).

Drone batteries are nasty pieces of work...

Indeed.

I wasn't paying enough attention when soldering a plug onto a 7 cell 5800mAhr 40c battery once. I melted the tip of my iron, and pretty much vapourised the plug's contacts... (The battery seemed fine about it - I got 6 or 8 months out of it powering a bicycle before it started to show signs of imminently-firey puffiness...)
