Right, my timer does not have any of those features, everything is in ESC, it has 4 types of protection: overcurrent, undervoltage, commutation, temperature. All of those 4 can cause motor stop in case of prop strike, however it is protection of ESC, not motor or battery, so for example current limit is not adjustable, it depends on ESC type and it is far over ESC rate, so for example overloaded motor (too large prop) will cause thermal cut off earlier then overcurrent.
Voltage protection is ususlay set to 2.9V but we all use it at 3.2V (max) just to switch off earlier in case of crash, it is necessary especially on indoors, which use rubber prop saver, so overcurrent or commutation error does not happen after crash.
