3.7V 350mAh LP-422339-PACK Li-Polymer Battery for Smart Wearables & IoT Devices


The LP-422339-PACK is a premium lithium-polymer (Li-Pol) battery engineered for small, power-efficient electronics, featuring a slim prismatic form factor (42mm × 23mm × 3.9mm), nominal 3.7V voltage (4.2V full charge), and 350mAh capacity—delivering 1.295Wh of reliable energy. Designed with Li-Pol’s signature flexible, thin profile, this battery merges space-saving design, lightweight construction, and stable performance, making it the ideal power source for wearables, mini IoT sensors, portable medical devices, and compact consumer gadgets that demand tiny, long-lasting power.
Core Advantages of Pouch Li-ion Design​
Crafted to solve the unique needs of miniaturized devices—where size and weight are critical:​
  • Ultra-Slim & Flexible Design: With a thickness of 4.4mm and prismatic shape, the LP-422339-PACK fits seamlessly into ultra-compact devices like wireless earbuds, smart hearing aids, mini fitness trackers, and micro IoT beacons. Its flexible Li-Pol structure adapts to tight, irregular spaces (unlike rigid cylindrical batteries), enabling sleeker, more ergonomic product designs for modern gadgets.​
  • 350mAh Targeted Capacity: Optimized for low-power devices, delivering balanced runtime: powering a pair of true wireless earbuds for 4-6 hours of continuous playback, a mini smartwatch for 2-3 days (basic features), a small IoT temperature sensor for 2-4 weeks (low-frequency data transmission), or a portable glucose meter for 10-15 uses. Perfect for devices where every millimeter and gram counts.​
  • Stable 3.7V Voltage Output: Maintains consistent 3.7V nominal voltage throughout discharge, avoiding the voltage drops that cause glitching, reduced functionality, or sudden shutdowns in sensitive small electronics. This stability is critical for precision devices like medical wearables or sensor modules, ensuring accurate performance until full depletion.​
  • Featherweight Construction: Weighing only 8.8g, it adds virtually no bulk to mini gadgets—essential for wearables that need to be lightweight and comfortable for all-day use. Its flat, compact profile maximizes space efficiency, allowing manufacturers to create thinner, more discreet devices.

Ideal For:
  • Wearable Technology: True wireless earbuds, smart hearing aids, mini fitness trackers, and compact smartwatches.
  • IoT & Sensors: Micro Bluetooth beacons, environmental monitoring sensors (temperature/humidity), and small GPS trackers.
  • Portable Medical Devices: Mini glucose meters, portable pulse oximeters, and small health monitors.
  • Compact Consumer Gadgets: Mini LED flashlights, portable keychain speakers, and tiny handheld game consoles.
  • DIY & Custom Projects: Small drones (micro models), Arduino-based gadgets, and custom wearable prototypes.
