The 3.7V 560mAh Lithium Polymer Battery is a compact, high-adaptability power solution tailored for small-scale portable electronics. Leveraging the flexibility and high energy density of lithium polymer (LiPo) technology, it strikes an ideal balance between size and performance, making it a go-to choice for devices where space and weight are critical constraints.
With a nominal voltage of 3.7V—consistent with the power requirements of most miniaturized electronics—it delivers steady output across its discharge cycle (ranging from 4.2V at full charge to 3.0V at safe cutoff). The 560mAh capacity is optimized for low-to-moderate power consumption devices: it powers wireless earbuds for 4–6 hours of continuous use, smart bracelets for 3–5 days of daily wear, or small Bluetooth trackers for up to 2 weeks, eliminating frequent recharging hassles.
Unlike rigid cylindrical batteries, this LiPo battery features a thin, flexible form factor that adapts to irregular device enclosures. Its slim profile (typically 3–5mm thick, depending on customization) fits seamlessly into ultra-thin wearables, mini IoT sensors, or compact medical gadgets (such as portable glucose monitors), without adding bulk. This flexibility also allows for custom cutting to match specific device dimensions, a key advantage for OEMs and DIY electronics projects.
Built with multi-layer protection mechanisms, it guards against overcharging, over-discharging, short circuits, and overheating—critical safeguards for devices that often interact with the human body (e.g., wearables) or operate in enclosed spaces. The LiPo chemistry also ensures low swelling risk (less than 2% volume expansion after 500 charge cycles) and long-term durability: it retains over 80% of its original capacity after 500 charge-discharge cycles, outperforming traditional nickel-cadmium batteries.
It supports standard 3.7V USB charging (via compatible chargers) and reaches 80% capacity in just 1.5 hours, minimizing downtime. Its low self-discharge rate (less than 4% per month) means it retains charge during storage—ideal for backup power in emergency sensors or infrequently used devices like portable thermometers.
Beyond consumer electronics, it powers industrial micro-sensors (e.g., temperature/humidity trackers), small drones (mini toy models), and portable audio accessories (e.g., wireless microphones). Its broad compatibility and compact size make it a versatile option for both commercial production and hobbyist projects.
