Nickel-cadmium battery low voltage indication circuit diagram of remote control helicopter

Published:2011/4/7 20:43:00 Author:Ecco | Keyword: Nickel-cadmium battery , low voltage indication , remote control helicopter

5.2V Nickel-cadmium battery low voltage indication 2 of remote control helicopter In the circuit, when the battery voltage is lower than the preset value, the bright indication can be used as detecting low voltage (use high brightness and large LED), since the original design is used in remote control helicopter, so you can choose a a specific color LED which could be watched in the day, the cutting off point is adjusted by the variable resistor P1 of which resistance is between 4.2 to 5.2V, the selection of parts is according to your choice, but proposed to be located between 4.6 to 4.8V. The design can also be used in other applications. According to the original design, when the LED is lit, the current is about 12mA, while the standby current is about 2mA.   (View)
