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.
