XTAR 21700 6000mAh Protected

The XTAR 21700 6000mAh is the undisputed endurance king of the XTAR lineup. Pushing the limits of current lithium-ion energy density, this ultra-high-capacity cell is designed for users who need their devices to stay powered for days, not hours. NOT FOR PARD DEVICES Included: 1 x Battery 1 x Cardboard Case XTAR 21700 6000mAh: The Ultimate Endurance Cell Unrivaled Capacity. Maximum Runtime. When your mission requires long-lasting power without the possibility of a recharge, the XTAR 6000mAh 21700 is the answer. By utilizing the latest high-density cell chemistry, XTAR has squeezed a massive 6000mAh into the 21700 form factor. This cell is optimized for low-to-medium drain devices where longevity is the primary goal, such as long-range LED searchlights, portable power banks, and custom high-capacity battery packs. Key Features Industry-Leading 6000mAh Capacity: Offers significantly more runtime than standard 4000mAh or 5000mAh 21700 cells, making it perfect for multi-day excursions or professional field work. True 3.6V/3.7V Nominal Voltage: Provides a stable energy platform for high-end electronics and power-hungry portable gear. Energy-Dense Chemistry: Advanced lithium-ion internals allow for maximum energy storage without increasing the standard 21700 physical footprint. Optimized for Longevity: While not a "high-amp" racing cell, it excels at providing steady, continuous power over long periods with minimal voltage drop. 500+ Recharge Cycles: Designed for long-term use, maintaining a high percentage of its original capacity even after hundreds of charge-discharge cycles. Ideal Use Cases This ultra-high capacity cell is best suited for: Long-Range Flashlights: Ideal for search-and-rescue or camping lights where a lower-intensity beam needs to stay on for the whole night. Power Bank DIY: The perfect building block for custom, lightweight portable power stations. E-Bike & EV Packs: Excellent for long-range battery builds where weight-to-capacity ratio is critical. Outdoor Gear: GPS units, trail monitoring equipment, and remote telemetry sensors.
