Redefining High-Rate Performance
The Lithonic INR21700 40HR lithium cell delivers 70A peak discharge and 60A continuous current with 95%+ capacity retention, ultra-low 4-6mΩ internal resistance, outperforming all competitors:
- Vs Samsung 40T: 60A continuous discharge crushes 35A limit, lower IR (4-6mΩ vs 10.55mΩ).
- Vs EVE 40P/40PL: 20% higher discharge capability (40A→60A) and 15% less capacity fade.
- Vs Molicel P42A: Superior IR (4-6mΩ vs AC 10mΩ/DC 16mΩ) and stability under extreme loads.
Key Performance Advantages
- Extreme Discharge Capability
- 70A Peak: Ideal for drones and power tools requiring instant burst, surpassing Samsung 40T’s 45A (with OTP).
- 60A Continuous: 95% capacity retention with only 32.6℃ temperature rise, 20% cooler than rivals.
- Ultra-Low IR Technology
- 4-6mΩ: 40% less energy loss, extended runtime, and fast charging (1.5C full charge in 1h2min).
- Military-Grade Thermal Control
