Hello,
I was wondering if anyone knows how much is the current draw of the CF???
The datasheet says the battery has a capacity of 170mAh, then the battery has a continious discharge rate of 25C.
That means capacity * discharge rate = 4.25 A / 4 motors = 1.0625 A each motor max.
If we apply a safety factor of 80% = 850mA each motor max. Which is the same as the motor specifications.
I want to confirm this, the datasheet also has a burst rate of 50C, how do I know I am not using this rate??? Is there a protection to use 25C all the time??? What could be the max current draw we can get from the battery???
Thanks!!!

Re: Crazyflie current draw
The PCM in the battery actually limits it, see the wiki. It is limited to about 4A continuous which ~25C as you calculated.
When the Crazyflie hovers it consumes around 1.5A in total and during bursts up to 4A.
