3.7V 50mAh LiPo Battery for TWS Earbuds

The 3.7V 50mAh LiPo Battery is a compact rechargeable lithium-polymer cell designed for small electronic devices with limited internal space. It is suitable for repairing compatible AirPods-style earbuds, TWS earphones, Bluetooth headsets, miniature speakers, and other low-power portable electronics.

With approximate dimensions of only 10 × 9 × 4.5mm, the battery can fit inside many compact wireless devices. However, dimensions, terminal position, polarity, and charging requirements must be checked before installation.

Compact Rechargeable Polymer Battery

This battery has a nominal voltage of 3.7V and a rated capacity of 50mAh. Furthermore, a fully charged single-cell lithium-polymer battery reaches approximately 4.2V.

The lightweight polymer pouch design provides useful energy storage without requiring a rigid cylindrical case. Therefore, it is particularly suitable for small wearable and audio products where internal space and weight are important.

Common Applications

The 3.7V 50mAh LiPo Battery can be used in compatible devices such as:

  • AirPods-style wireless earbuds
  • TWS Bluetooth earphones
  • Compact Bluetooth headsets
  • Miniature Bluetooth audio devices
  • Small wearable electronics
  • Mini tracking devices
  • Compact rechargeable toys
  • Low-power sensors and IoT projects
  • DIY miniature electronic circuits
  • Replacement and maintenance projects

Compatibility Requirements

Before purchasing or installing the battery, compare the old battery’s voltage, dimensions, wire arrangement, connector, and polarity. A matching voltage and capacity do not guarantee physical compatibility.

The battery should only be charged using a charger or device designed for a single 3.7V lithium-polymer cell with a maximum charging voltage of 4.2V. Do not connect it directly to a 5V power source.

Installation and Safety Instructions

Lithium-polymer batteries must be handled carefully. Do not bend, puncture, crush, open, short-circuit, or expose the cell to fire or excessive heat.

Confirm the positive and negative terminals before installation because reversed polarity may damage the battery or connected device. In addition, avoid applying prolonged soldering heat directly to the battery terminals.

Do not use the battery if it is swollen, damaged, leaking, overheated, or physically deformed. Also, make sure that the original device provides appropriate charging and battery-protection circuitry.

Installation inside AirPods or TWS earbuds may require precision soldering and disassembly experience. Therefore, professional installation is recommended when replacing the battery inside sealed or delicate electronic products.
