The greater the current the higher the battery impedance
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
In general, a higher impedance can lead to better sound quality. This is because a higher impedance can help to reduce distortion and noise in the audio signal. With a higher impedance, the audio device is better able to control the flow of electrical current, which can result in a cleaner, clearer sound.
