Switch-Mode Smart BEC with Lithium Cutoff

The SmartBEC adds the benefits of a switching BEC and a lithium-aware LVC to your flight system. It is a great choice for anyone looking to upgrade their non-lithium aware system to use higher voltage lithium batteries. SmartBEC features a soft lithium cutoff, so you don't have to worry about making an emergency dead-stick landing. When the battery is nearly depleted, the power output of the motor is progressively scaled down. Once the plane begins to feel sluggish, it's time to set up for a landing. SmartBEC uses a switching type power supply to efficiently convert high pack voltages into the 5v your receiver and radio gear needs. A switching BEC does not become grossly inefficient when used from high voltage sources. Because of this you will not need to fear losing radio power from a BEC shutdown. Adding a SmartBEC will allow you to stop carrying around a second receiver battery, often saving several ounces of weight. SmartBEC supports up to four standard servos or six sub-micro servos, so the majority of sport and parkflyer type aircraft are suitable. It puts out almost no EMI, so you can use it without fear of glitching. The SmartBEC installs between your ESC and receiver, so you don't have to modify your speed control to disable its internal BEC, just plug it in. SmartBEC works by modifying the throttle commands sent to the ESC, so if the ESC has low voltage cutoff settings, they will still be active. Whichever LVC occurs first (ESC or SmartBEC) will take precedence. SmartBEC automatically detects the number of series lithium cells, and displays this information by flashing a light. After connecting the battery and prior to flying, make sure that the SmartBEC has detected the correct number of cells. As a safety precaution, SmartBEC will not arm the ESC for pack voltages lower than 9V or higher than 34V.
