Power your compact electronics with a reliable 602040 lithium polymer (Li-Po) rechargeable battery cell. Designed for space-constrained applications, this 3.7V 500mAh battery is a popular choice for DIY electronics, prototypes, and replacement battery needs where a thin, lightweight power source is required.
The 602040 form factor is widely used in smart wearables, GPS trackers, portable media devices, small game consoles, and communication gadgets. With a 500mAh capacity, it offers a practical balance between runtime and size, making it suitable for microcontroller projects, BLE/WiFi low-power devices (with appropriate power management), and portable sensor nodes.
This battery includes a pre-attached 2-wire lead to simplify installation into your device or project. For best results, pair it with a proper Li-Po charging/protection circuit and ensure your device supports single-cell 3.7V Li-Po chemistry. Always confirm physical dimensions, polarity, and connector compatibility before ordering or installing.
Safety and usage notes:
Li-Po batteries must be charged using a compatible single-cell Li-Po charger (CC/CV profile). Do not short-circuit, puncture, crush, overheat, or expose to water. If your application does not include protection circuitry, use a protection/charging module to help prevent overcharge, over-discharge, and overcurrent conditions. Store in a cool, dry place and avoid operating outside recommended temperature ranges.
