Key Technical Advantages of the Tenpower INR21700-50XG

High Capacity for Extended Mission Profiles

The 5000mAh nominal capacity provides a meaningful boost over traditional 18650 cells, enabling longer flight durations or extended operational cycles. For UAV developers, more capacity inside the same pack footprint translates directly into improved endurance without restructuring aircraft geometry. Industrial users benefit from longer tool run times and reduced swap cycles in the field.

Exceptional Current Handling for High-Demand Loads

One of the most defining strengths of this model is its flexible discharge performance:

• 40A continuous discharge without temperature cut-off
• 90A continuous discharge with a 75°C cut-off
• 140A pulse discharge capability (3 seconds)

This combination allows the INR21700-50XG to handle aggressive current spikes typically generated by UAV motors during takeoff, hover stabilization, or emergency maneuvers. Ground equipment, such as high-output spotlights or torque-intensive tools, also benefits from the available burst power.

MotioNew’s integration team ensures that current delivery stability and voltage sag behavior match your ESC or power distribution system, particularly in aircraft or robotics that rely on fast transient response.

Advanced Thermal Performance and Safety Behavior

Reliable temperature cut-off behavior provides an added layer of protection during high-drain cycles. The 75°C threshold is tuned to preserve cell longevity without prematurely limiting output, which is especially important for hot-weather operations or enclosed battery compartments. High-density applications such as compact flight controller modules and internal power conditioning circuits can be designed with predictable thermal patterns when paired with this cell.

Applications Across UAV and Industrial Ecosystems

The Tenpower INR21700-50XG allows manufacturers to build flexible battery platforms that support:

• Long-endurance UAV propulsion packs
• VTOL transition aircraft with high burst current demands
• Multirotor stabilization systems with fast current fluctuations
• Portable industrial tools and field equipment
• Robotics power cores that require steady voltage
• Custom modular battery arrays for high-drain systems

In UAV contexts, pairing these cells with appropriate BMS configurations ensures balanced health monitoring, cell protection, and long-term performance. MotioNew can provide guidance on pack architecture, connection strategies, and compatibility with charging systems used across different aerospace and industrial programs.
