XTAR 21700 5000mAh 15A

The XTAR 21700 5000mAh 15A cell is a high-capacity, high-performance lithium-ion battery designed for reliable, long-lasting power in demanding applications. With a generous 5000mAh capacity, it delivers extended runtime for high-drain devices such as high-lumen flashlights, and power banks.

Engineered for stable, consistent output, the cell supports a 15A continuous discharge, making it ideal for devices that require sustained power without voltage drop. While lower than the 35A model, this discharge rate enables improved cycle life and thermal stability, contributing to longer overall performance. With a proven lifespan of over 500 charge and discharge cycles under normal use, this battery offers excellent durability and cost-effectiveness over time.

Built to perform in harsh conditions, the cell operates reliably across a wide temperature range—from -20°C to +60°C—ensuring dependable function in cold winter environments or hot outdoor settings. As an unprotected cell, it lacks a built-in protection circuit, making it suitable only for use in devices with integrated safety features.
