Help!

ESC burns when dropping throttle to zero


Hi all. This is my second drone and the first non-racing/ardupilot build.
FC: H743-SLIM
MOTORS: Racerstar BR4114 340KV
ESC: T-Motor ESC VELOX 45A V2

Drone is on the bench with no props. I power the drone using HOTA D6 Pro providing 6S/15A power. (is 15A too much?)

I can run full throttle with no problem. When I slowly-gradually lower the throttle to zero, then FC reboots (exactly when at zero throttle). When I abruptly lower the throttle to zero, the ESC is burned (again exactly at zero throttle). This had happened twice.
Am I missing something obvious? Any ideas/help is appreciated.

Does blheli_32 brake has anything to do?
