How many amps?

[SkyLogicAerial]

Hello everyone, new user here and thanks for having me aboard.

I have a question, I am trying to calculate how many amps one of our Drones uses during flight.

Can anyone help me figure out (around) how many amps one of our drone's is drawing by these stats:

22.8V DC Battery
5700mah
129.96wh
Battery drains in 25min

My thoughts are about 5amps

I know how to test it manually but would rather not mount a amp meter to the drone during flight to see the max output.

Any help would be greatly appreciated.

Thanks, Steve

Well, 5 amps is not quite right. Basically, you have to divide the capacity of 5700 mAh, which is 5.7 Ah, by the number of hours... 25 min. would be 0.416666 hours. The result would be 13.68 amps. That is, if the battery is able to give the full 5.7 Ah at that load. Most batteries' usable capacity diminishes the more the battery is loaded. But that depends on your battery and isn't an universal formula. But I estimate the result may be between 0-20% too high, so the range would be somewhere between 12 and 13 amps, probably
