Hello there, today I got my first bad build. I was building a 65mm 30.000kv 1s.

I hooked the Bt2.0 connector, cleaned it with alcohol, (No visible sort) hooked a battery on it to see if it flashes like it is supposed to. Insta smoke from the FC and the battery expanded crazy.

Not sure if it is user error or a defect PCB but it was funny, threw it in my yard while running to make saltwater to kill it. Let's wait another month for another AIO to arrive haha.

Here is a photo, see if something is wrong with it because I see no problem with the solder
