Readytosky RC 20A Brush ESC Motor Speed Controller w/Brake for RC Car Boat Tank(2PCS)

Does it have lipo cutoff?

Anyone has a manual? It was not included in the delivered package. I need to know functions of switches, which cable is battery, which is motor, etc

Do these controllers have any braking function? The ones I got do not.

whats a good servo for this esc?
