These power sources, typically employing lithium-based chemistries, provide a nominal voltage around 7.4 volts. Such a configuration is frequently used to energize radio receivers in remote-controlled devices, ensuring reliable operation. An example application would be powering the receiver in a model aircraft or remote-controlled car, allowing the user to maintain control from a distance.
The utilization of this type of power supply is crucial for ensuring adequate performance and runtime of the electronic devices they support. Historically, nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries were common. However, the improved energy density and lighter weight offered by lithium-based options have made them increasingly popular. This transition leads to extended operational periods and enhanced maneuverability for remote-controlled models.
