The 3.7V 1200mAh 1S LiPo Battery is a lightweight, high-performance rechargeable lithium polymer (LiPo) battery designed for compact electronic devices and DIY electronics projects. With a single-cell (1S) configuration and 1200mAh capacity, it provides reliable power for microcontrollers, IoT devices, drones, RC toys, wearable tech, and more.

This battery offers a balance between high energy density and low weight, making it ideal for portable and battery-powered projects that require long-lasting power in a small footprint.

How It Works:
This 1S LiPo battery outputs a nominal 3.7V, and can be charged using a standard LiPo charger or charge protection board. Once fully charged (up to 4.2V), it can power low-voltage devices efficiently and steadily. Be sure to use a protection circuit or battery management system (BMS) to prevent overcharge, over-discharge, or short-circuiting.
