XTAR 21700 5000mAh 35A

The XTAR 21700 5000mAh 35A RAW cell is a high-capacity, high-performance lithium-ion battery engineered for demanding applications. With a 5000mAh capacity, it delivers extended runtime for high-drain devices such as high-lumen flashlights, and portable power banks—ideal for prolonged use without frequent recharging.

Built for power, the cell supports a 35A continuous discharge and a 90A peak current (2 seconds), making it suitable for devices requiring high bursts of energy. This robust output ensures stable voltage under load, preventing performance drop in demanding conditions. While the higher discharge rate reduces cycle life compared to lower-drain models, it delivers unmatched power for performance-critical applications.

Designed for extreme environments, the cell operates reliably from -20°C to +60°C, maintaining consistent performance in cold winter conditions or hot outdoor settings. As an unprotected cell, it lacks a built-in protection circuit, so it is intended for use only in devices with integrated safety features such as over-current, over-temperature, and over-discharge protection.
