Building a 2.5in 18650 drone and I'm getting this weird behavior from my ESCs. I'm not reaching the current limit and the issue happens regardless of input voltage, but it's more noticeable when flying at low voltages because the ESCs reach full throttle more quickly. Could this be a Dshot/firmware issue? I used this same prop/motor/battery combo on another quad with an air65 AIO with no problems.

If you can't hear it, the motor cuts to about half throttle as soon as that channel reaches full throttle

More testing and it kinda seems like this "12a" esc thinks it's a 5a or something

Look at your voltage ⚡😁 seems a little low as you pump out the amps. How charged / old is this battery?

Its an 18650 Li ion cell but the behavior is exactly the same on LiPo

Will do when I get home from work tonight

Honestly I give up, im just gonna throw another 5in1 on it. I'm assuming I got a bad FC

What kind of cell are you using? Most will start acting like this between 2.5v and 3v. Especially when you try and pull 25A out of them at low voltage.

But i tried it with a full lipo (3.7v at full load) and it still does it
Reflashed all of the ESCs too

So the voltage drops to 3.7v at full throttle on a lipo? This is reffered to as voltage sag. What kv motors are you using? What's your pid frequency set to? And what is your p-gain set to?

🤷 i already replaced the aio lol

Hmmm, I'd go for an X12 or something next build like this.
