Unmatched Performance Specifications
The INR21700-50XG is designed where both runtime and peak power are critical. It provides the energy to last and the punch to perform.
-
High Energy Density: 5000mAh nominal capacity for extended operational time.
-
Extreme Discharge Capability:
-
Continuous Discharge: 90A (with 75°C temperature cut-off)
-
Pulse Discharge: 140A for 3 seconds
-
-
Maximum Efficiency: Ultra-low internal impedance (≤4mΩ) minimizes energy loss as heat, ensuring stable voltage and superior performance under heavy loads.
-
Rapid Charging: Supports maximum charging currents of up to 15A.
Engineered for Reliability and Longevity
Performance is nothing without consistency. The INR21700-50XG is built to withstand rigorous use, ensuring long-term value and reliability.

-
Proven Safety: Compliant with stringent international safety standards, successfully passing tests including Overcharge, Short-Circuit, Crush, Thermal Shock, and Impact.
-
Wide Operating Range: Optimized for discharge in environments from -20°C to 60°C.
Verified Quality: Performance You Can Trust
Our commitment to quality ensures that every cell not only meets but often exceeds its published specifications. Real-world production data consistently shows:
-
Actual Delivered Capacity: 5075 – 5100mAh
-
Actual Measured Impedance: 2.3 – 2.6mΩ
This consistent over-performance provides a critical safety margin for your designs, guaranteeing that your end product will deliver on its promises.
Ideal Applications
The INR21700-50XG is the optimal power source for a wide range of high-drain devices, including:
-
Professional Power Tools: (e.g., High-torque drills, circular saws, angle grinders)
-
Electric Mobility: (e.g., Performance e-Bikes, e-Scooters, Drones)
-
High-Performance Hobbyist RC Vehicles: (e.g., Race-grade drones, RC cars, and boats)
-
Critical Backup Systems: (e.g., UPS, Portable Power Stations)
The Technology Advantage: Full-Pole Tab Design
The cornerstone of the INR21700-50XG’s superior performance is its innovative Full-Pole Tab design. This technology dramatically reduces the path of internal current flow, resulting in significantly lower resistance, better heat dissipation, higher discharge capability, and enhanced cycle life compared to conventional cells.
