6S3P Quantum INR21700-50TB Li-ion Battery Pack – 15000mAh

The Quantum 50TB 6S3P 21700 battery pack is a high-power, high-discharge lithium-ion unit engineered to deliver extreme current output with minimal voltage sag. It ensures stable performance for FPV drones (including long-range, kamikaze, and strike platforms), RC models, and other high-load devices. Utilizing state-of-the-art Quantum INR21700-50TB cells—capable of a continuous discharge current of up to 60A—this battery pack excels under intense dynamic loads without overheating or power loss.

Features:

Ultra-high-discharge Quantum 50TB cells: These next-generation cells support a continuous discharge current of up to 60A (with even higher peak currents) and feature ultra-low internal resistance (down to 4 mΩ).

High capacity (15000 mAh): Provides extended flight times, reducing the need for frequent battery swaps.

6S configuration: A nominal voltage of 22.2V delivers the high power required for demanding drone operations and high-load RC models.

3P design: Three parallel strings of cells offer an optimal balance between current-handling capabilities, weight, and safety. High Discharge Current: The battery easily handles extreme current loads without overheating or significant voltage sag.

Minimal Voltage Sag: Thanks to the cells' exceptional current delivery, high voltage is maintained even at full throttle.

Robust Construction: A durable protective casing, high-efficiency welding with copper-nickel busbars, and quality assembly protect the pack against mechanical damage and vibrations.

High Energy Density: 21700 Li-ion cells offer superior energy density compared to traditional LiPo batteries.

Compatibility: Ideally suited for large FPV drones (7–10 inches), heavy-lift quadcopters, fixed-wing UAVs, and RC models. Specifications:

Advantages:

Top-tier Performance: One of the most powerful battery packs in its class, offering output comparable to LiPo solutions.

Low Heat Generation: High current-handling headroom ensures the cells remain only moderately warm during intensive flights.

Safe Operation: High-quality components guarantee stable performance even under critical loads.

Versatility: Compatible with various types of heavy-duty UAVs and models, thanks to standard power connectors.

Compact and Lightweight: An optimal weight-to-capacity ratio helps minimize the drone's overall weight.

Usage Recommendations:

Use only appropriate chargers designed for Li-ion batteries that support cell balancing. Avoid overcharging and deep discharging the battery (do not go below 2.5 V per cell / 15 V for the entire pack).

Ensure the battery casing and protective outer wrap remain undamaged.

Store the battery in "Storage" mode (at approximately 50–60% charge, or 3.6–3.8 V per cell) to extend its service life.

Before each use, check the condition of the power connectors and the balance lead, and ensure the outer wrap is intact.
