Does the ServoStation have a low voltage cutout?
Not deliberately, no, but like most electronic devices if the supply voltage goes low enough, it will stop working (see above). Low voltage cutouts exist to prevent batteries from becoming too depleted. This is important because some types of batteries – notably Lithium Polymers (LiPos) – can suffer permanent damage if discharged too far. Low voltage cutouts are normally implemented by ESCs and work by cutting power to the motor when the battery voltage falls to a predetermined level. At this point the radio receiver and servos should remain operational so that landing can be attempted. Although low voltage cutouts are generally a good idea, they are not always appropriate. Helis, for example, tend to respond poorly to sudden loss of power to the main rotor. An alternative strategy is required, which is getting a little beyond the scope of this document. The ServoStation is guaranteed to work down to 8 volts, so if a low voltage cutout is programmed into your ESC it should be set to mo
