6S3P 21700 Li-ion Battery Pack (Samsung 50S) – 15000mAh

The 6S3P 21700 Samsung 50S battery pack is a high-capacity, ultra-powerful, and highly efficient lithium-ion power source. It is designed to deliver extended flight times, high current output, and stable power for heavy-duty FPV drones (long-range), cargo UAVs, RC models, and autonomous robotic platforms. Utilizing genuine Samsung INR21700-50S cells in a 6S3P configuration, this battery offers a massive energy reserve and excellent resilience under peak loads.

Features:

Ultra-high capacity: An impressive 15000mAh ensures maximum autonomy and long mission durations without the need for frequent battery swaps.

Premium Samsung 50S cells: Original INR21700-50S cells feature minimal internal resistance and maintain stable voltage even under high current loads.

6S configuration: A nominal voltage of 22.2V provides powerful and stable operation for UAV propulsion systems and heavy equipment.

3P design: A triple-parallel connection (comprising 18 cells) distributes the load evenly, significantly reducing heat generation and increasing the pack's total operating current capacity. High Discharge Current: Ensures reliable performance in demanding conditions with high peak loads.

Robust and Durable Construction: High-quality busbar layout, precision welding, and a durable protective casing safeguard the battery against mechanical impact and vibration.

Compatibility: An ideal choice for large FPV drones (8–10+ inches), heavy-lift quadcopters, fixed-wing UAVs (reconnaissance/relay drones), and heavy-duty RC ground platforms.
