The 3.7V 350mAh 1S LiPo Battery is a compact, lightweight lithium polymer rechargeable battery perfect for powering low-power electronic projects and portable devices. With a single-cell (1S) configuration and 350mAh capacity, it delivers reliable energy in a small form factor, making it ideal for wearables, small RC models, mini robots, and embedded systems.
Its slim design and stable voltage output make it especially useful for Arduino, ESP8266/ESP32, and IoT-based applications where space-saving and weight reduction are key.
How It Works:
This LiPo battery provides a nominal output of 3.7V, with a maximum charge voltage of 4.2V. When used with a compatible LiPo charging module (such as TP4056), it ensures safe and efficient charging. It can be integrated directly into low-voltage circuits or through a boost converter if higher voltage is needed.
