Rechargeable Lifepo4 Battery Cell 502030 3.7v 250mAh 0.925wh Power Lithium Ion Polymer Battery

Key Features:

Strong voltage compatibility and versatility: The 3.7V nominal voltage is the mainstream voltage for micro electronic devices, requiring no additional power supply circuitry and directly compatible with the power management systems of most low-power devices.

Safety and durability standards: Equipped with a miniature protection board, it features basic protection against overcharge, over-discharge, and short circuits; approximately 500 cycle times under 0.2C charge/discharge conditions, with a monthly self-discharge rate ≤3%, suitable for long standby periods.

Flexible installation and easy integration: Soft-pack packaging without a rigid outer shell allows for slight bending to fit into the irregular internal spaces of micro devices, facilitating lightweight design.

Main Applications:

Smart wearable micro devices: Small smart bracelets, children's GPS watches (mini version), mini motion trackers. The mini size does not increase wearing burden, and the 250mAh capacity provides 1-2 days of low-power use (supports basic functions such as location tracking and step counting).

Miniature Digital Devices: Mini Bluetooth headsets (single ear), miniature voice recorders, ultra-small MP3 players, miniature cameras (pinhole/wearable), supporting 3-6 hours of use with low power consumption.

IoT Miniature Terminals: Miniature wireless sensors (temperature and humidity, door and window sensors), RFID smart tags, miniature data collectors; low self-discharge rate suitable for long standby times, miniature size for concealed installation.

Portable Miniature Medical Devices: Children's fingertip blood glucose meters, mini pulse oximeters, miniature massagers (acupressure massage); ternary materials ensure stable discharge, meeting the precise power supply needs of miniature medical devices.

Small Toys and Models: Miniature remote control cars, miniature drones (children's toy models), miniature robots; compact size fits the lightweight design of toys, low-rate discharge meets the basic power needs of toys.

Miniature Backup Power Supplies: Miniature auxiliary power supplies for smart door locks, emergency power supplies for small electronic devices (such as miniature voice recorders); small capacity is perfect for short-term emergency power supply scenarios.
