Hi all,


have some problem with my Mamba F405 mini ESC. After ACC calibration with my Taranis, after using secound Lipo battery suddenly my drone tuned off.

Now when i plugin battery, i have only V5 in FC.
ESC not working, no beeping, also BLheli dosnt see it.
Im new in this Hobby, and its my first quad. I've been flying it for 2 weeks without any issue. Until today D:

Its can happen becouse i mounted realy close ESC near FC? Then some parts get to hot?
I checked all connentions between + and each motor wires. Everywhere is ~15V.
In attachments 2 pictures form this ESC.
Im realy confused and in future want to avoid it.
Can someone give me some sugestions, how its could happend?

BR,
Cvbn

You should get 3 beeps if your ESCs are working. I can't imagine that all 4 of the ESCs just went bad.
