Lipo capacity in drone spec.

[albertly]

Many drone manufactures give exact capacity of a battery.

For example:

"Support 3S 450mAh-4S 450mAh battery(Don’t more than 4S 450mAh)"

Why this is important? "Don’t more than 4S 450mAh" - but if more what's going to happen?
It is clear that the more capacity the more the weight of battery.
Besides that is there any electricity/physics aspect? For example is it possible to burn down FC or ESC with bigger capacity?

Or it's only about weight ?

However if it only about weight :
3S 300mAh Weight: 24 g
3S 380mAh Weight: 27 g

With the weight of the drone (geprc SMART/phantom 2.5" toothpick freestyle) 51g + 24g = 75g

3g / 75g = 0.04

So 4% difference. What is all the fuss about?

The "Support 3S 450mAh-4S 450mAh battery(Don’t more than 4S 450mAh)" might be chinglish that's intended to mean that 4s is the limit and you shouldn't use >4s, not that 450mAh is the limit and you shouldn't use >450mAh. 5s or more on an ESC meant for 4s would definitely blow stuff up.
