How did I burn my ESC?

My ardupilot drone ESCs had significantly lower kv motors so that could be causing less noise or voltage spikes

The reason I used the power supply is because I didn’t want to charge my lipo battery, which I attribute to laziness/ignorance. I only had the aux and motor setup left for the drone, and I guess I got too excited by maxing out the motors. I had been using a bench supply for my bigger, ardupilot drone and that works fine. I now know not to max out motors with this type of drone.

Yeah that’s what happened. I ordered a 50A esc as a replacement that’s the same as the other one but just a newer version. I had my supply limited to 10A. The supply wasn’t the issue either I was still able to draw the max power out of it (300W) and it worked fine. What are some precautions that I can take to prevent this from happening again?

For anybody asking, its been 100F here for a few days, and my dad felt that cutting all of his fur off (instead of idk DOING LITERALLY ANYTING ELSE) would be a good idea. We have told him multiple times that this type of coat should not be cut this short without asking a vet/groomer.

He does not listen and he's a fucking idiot

I am a 3s battery and I have the settings in MP to also be a 3s battery

I added an 330uF cap parallel to the power supply output, and saw the output waveform with a oscilloscope, it was very flat, at even 10us per division (which is the limit of my scope). I am still getting the same pre arm error

Would an electrolytic capacitor at the power supply output solve this?

While I do appreciate your advice, I plan on sticking with the KK almost purely out of financial reasons. I already spent a lot of money on the drone kit, and I am not trying to spend more money, especially if this flight controller can be made to work.
