It seems like these battery threads go on forever...but that's ok.
For those of you not familiar with battery discharge profiles (above), there is significance in the C rates (the different colored curves)...especially for high discharge devices like drones. For example, while hovering in place may require <1C, "flooring" the drone (just like a car) or extended use of Sport mode may be >>1C. You can see how the knee of the curve (and voltage) drops at higher C rates...which is the basis of my original comment about not flying below 20% SOC. Here's a drone recipe for disaster: flying at low SOC, on a hot day, you "floor" it (in Sport mode no less)...and it suddenly drops from the sky. Sound like something you've read about? YMMV.
