Description
3.7V 90mAh LiPo Rechargeable Battery – Compact Power for Mini Electronics
The 3.7V 90mAh Lithium Polymer (LiPo) Battery is a compact and lightweight power solution designed for small electronic devices, wearables, and DIY projects. Built with Lithium Polymer technology, this single-cell battery delivers stable voltage output and efficient energy performance in a minimal form factor.
With a nominal voltage of 3.7V (ranging from 4.2V fully charged to ~3.2V discharge), this battery is ideal for low-power applications such as microcontrollers, IoT devices, Bluetooth modules, and mini drones. Its small size makes it perfect for projects where space and weight are critical.
⚠ Note: This battery does not include built-in protection circuitry, so an external protection module (PCM/BMS) is recommended for safe usage.
