Description:

LP-443440-1S-3M Li poly Battery Pack 3.7V 560mAh Rechargeable Polymer Cell for Bluetooth IoT Wearable Devices

The 3.7V 560mAh LP-443440-1S-3M Lithium Polymer Battery is a compact, high-efficiency power solution tailored for miniaturized electronics. Its diminutive size and reliable performance make it an ideal choice for devices where space is at a premium, without sacrificing energy output.

Essential Performance Traits
Operating at a nominal 3.7V, this battery delivers a steady power supply within a safe range of 4.2V (full charge) to 2.5V (discharge cutoff). With a 560mAh capacity, it’s perfectly calibrated for low-power devices like wireless earbuds and small sensors, providing consistent runtime for daily use. The 1S single-cell design ensures simple integration into compact circuits.

Ultra-Compact Form Factor
Following the LP-443440 specification, this battery features a slim, lightweight build that fits seamlessly into tight enclosures. Its compact dimensions make it suitable for devices such as Bluetooth tags, miniaturized medical monitors, and portable IoT gadgets, where bulk and weight could compromise functionality.

Safety and Durability
Equipped with a multi-layer protection system, it guards against overcharging, over-discharging, and short circuits—critical for small devices where battery safety is paramount. The lithium polymer chemistry ensures stable performance over 300+ charge cycles, with minimal capacity loss. Its low swelling risk adds to long-term reliability, even in continuous-use scenarios.

Versatile Compatibility
The integrated 3M connector enables plug-and-play functionality with a range of small electronics. Its low self-discharge rate ensures it retains charge during storage, making it ideal for backup power in emergency sensors or infrequently used devices.

Efficient Charging
Compatible with standard 3.7V micro-chargers, it reaches 80% capacity in under 90 minutes, minimizing downtime for daily-use gadgets. Its efficient energy conversion ensures every mAh is utilized, extending time between charges for user convenience.
