In scenarios such as live streaming, outdoor interviews and short video shooting, portable wireless microphones (lavalier mics) are key devices to improve audio quality. Their core requirements for batteries are: small and lightweight without weighing down the collar, fast charging and low noise, and long-time continuous recording.
A one-to-two wireless lavalier microphone launched by an audio equipment manufacturer once faced pain points: traditional batteries are heavy, and the collar sags when worn, affecting the appearance; the battery life is insufficient, and the battery needs to be replaced after 4 hours of outdoor live streaming, interrupting the shooting rhythm.
To meet these needs, the manufacturer selected the LP-503759P-1S-3M lithium polymer battery to power the microphone.
