Key Features
- High Energy Capacity: 5000mAh nominal capacity supports extended runtime in demanding applications.
- Extreme Discharge Capability: Up to 40A continuous discharge without temperature cutoff and up to 90A with 75°C cutoff.
- Ultra-Low Internal Resistance: ≤4mΩ (AC 1kHz @ 25°C, 30% SOC) minimizes voltage sag and improves efficiency.
- High-Power INR Chemistry: Lithium-ion formulation optimized for stability, performance, and durability.
- Flat Top Unprotected Design: Intended for integration into engineered battery packs with appropriate BMS and protection circuitry.
Overview
The TENPOWER INR21700-50XG is a high-output lithium-ion battery cell engineered for professional applications that demand both high current delivery and strong energy density. Featuring a 5000mAh nominal capacity and exceptionally low internal resistance, the 50XG provides stable voltage performance and reduced thermal stress under load. Designed for battery pack assembly, this flat-top unprotected cell delivers up to 40A continuous discharge — and up to 90A continuous when operating with a temperature cutoff — making it ideal for advanced power systems and high-performance mobility solutions.
Applications / Uses
- Electric vehicles and e-mobility systems
- High-performance battery pack assemblies
