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.
