3.7V 18mAh Curved Battery 160630 — Ultra-Compact Flexible Lipo Cell

The 3.7 V 18mAh Curved Battery 160630 is a compact, ultra-thin power solution designed for next-generation wearables and smart mini-devices. If you're searching for a reliable curved battery or curved LiPo battery for small electronics, this guide explains everything you need to know—how it works, where it performs best, and why its unique bend-friendly design is transforming flexible power applications.

Part 1. What is a curved LiPo battery?

A curved battery, also called a curved LiPo or curved-by-LiPo cell, is a lithium-polymer battery engineered with a gently arched structure. Unlike flat LiPo batteries, the 160630 model adapts to surfaces that are rounded, contoured, or ergonomically shaped. This allows device designers to make products thinner, lighter, and more comfortable to wear—without compromising reliability or safety. The 3.7 V 18mAh Curved Battery 160630 uses high-efficiency polymer chemistry to provide stable output for low-power devices requiring continuous operation in a minimal footprint. Its micro-capacity is ideal for compact electronics where every millimeter matters.
