Lithium Polymer Lipo Rechargeable Battery 3.7V 320mAH

Lithium Polymer Lipo Rechargeable Battery 3.7V 320mAH 

The 3.7V 320mAh Lithium Polymer (Li-Po) Rechargeable Battery is a compact, lightweight, and high-performance energy solution designed for modern portable electronics. Built with advanced lithium-polymer chemistry, the cell offers excellent energy density relative to its size, making it ideal for applications where space and weight are critical. Its thin, flat form factor allows integration into slim devices without compromising design aesthetics or power capability.

This Li-Po cell provides a stable nominal voltage of 3.7V, with charging voltage typically up to 4.2V, ensuring consistent and efficient power delivery throughout its discharge cycle. With a capacity of 320mAh, the battery is suitable for applications requiring moderate run time with low to medium current consumption.

The battery construction includes high-grade electrode materials, ensuring long cycle life, minimal voltage drop, and high reliability. When combined with an appropriate protection circuit module (PCM), it safeguards against overcharge, over-discharge, short circuits, and excessive current, enhancing both safety and durability.

Due to its low self-discharge, the battery maintains charge even after long periods of inactivity, making it suitable for standby and intermittent-use applications. Its chemical stability and consistent discharge characteristics make it a preferred choice for IoT devices, wearable gadgets, and miniature consumer electronics.
