Molicel INR21700-P45B High-Rate Lithium-Ion Cell

Molicel INR21700-P45B High-Rate Lithium-Ion Cell

Introduction: Key Specifications

The Molicel INR21700-P45B is a cutting-edge lithium-ion cell engineered for extreme power applications.

With a 4.5Ah typical capacity (4.35Ah minimum) and a nominal voltage of 3.6V, it delivers a 45A continuous discharge current (10C rate).

Featuring rapid charging (9A maximum) and an ultra-wide operating temperature range (charge: 0~60℃, discharge: -40~60℃), this cell excels in high-demand scenarios such as power tools, drones, and energy storage systems, backed by UN38.3 and UL1642 certifications.

Core Features

1. 45A Continuous Discharge & 10C High-Rate Performance
   Designed for peak power demands, the P45B provides stable 45A continuous discharge (cut-off at 2.5V) with superior burst capability. Its discharge rate spans 0.2C to 10C (45A/4.5Ah), ideal for heavy-load applications.
2. Extreme Temperature Resilience
   • Subzero Operation: Maintains ≥3.51Ah capacity at -30℃ (cut-off 2.0V).
   • High-Temperature Stability: Delivers ≥4.35Ah at 60℃ with minimal degradation.
3. Fast Charging & Efficiency
   • Rapid Charge: 4.5A standard charge completes in 1.5 hours; supports 9A fast charging (temperature-dependent).
   • Low Impedance: ≤8mΩ AC impedance ensures 95%+ energy efficiency.
4. Longevity & Safety
   • Cycle Life: Retains ≥70% capacity after 500 cycles at 20A discharge.
   • Safety Compliance: Passes overcharge, short-circuit, crush, and thermal shock tests (up to 130℃).
5. Compact & Lightweight
   • Dimensions: 21.4mm diameter × 70mm height, ≤70g weight.

Applications

• Power Tools: Chainsaws, industrial drills, and heavy machinery.
• E-Bikes/EVs: High torque and extended runtime.
• Energy Storage: Reliable backup for off-grid and outdoor systems.
