Unleash Extreme Power with Lithonic INR21700 40HR: 4000mAh 70A Discharge, Unbeatable Price & Ultra-LowRevolutionize High-Drain Performance
21700 4000mAh 70A discharge battery——The Lithonic INR21700 40HR delivers unprecedented 70A continuous discharge with 4000mAh capacity – outperforming premium rivals at 40% lower cost. Engineered for drones, power tools, and EVs, its <5mΩ ultra-low resistance (tested at 25±1°C per IEC 61960) solves critical pain points: voltage drop, overheating, and short runtime in extreme-load applications.
Validated Technical Dominance
Based on third-party lab reports (available upon request):
- 🔋 Real-World Capacity:
- 3,922mAh maintained at 40A continuous discharge (98% efficiency)
- 3,840mAh sustained at 60A discharge (96% efficiency)
- ⚡ Resistance Benchmark: 4-6mΩ AC impedance (beats Samsung 40T’s 12mΩ)
- 🛡️ Safety First: Stable discharge curves even at 70A, with dual PTC protection
- ♻️ 500+ Cycles: 80% capacity retention after 500 cycles @ 20A discharge (Section 4.3)
