Molicel INR21700-P42A High-Rate Li-Ion Cell

Molicel INR21700 P42A High Rate Li-Ion Cell

Introduction: Key Specifications

The Molicel INR21700-P42A is a premium lithium-ion cell  with a 4200mAh typical capacity (4000mAh minimum) and a nominal voltage of 3.6V, it delivers an industry-leading 45A continuous discharge current (≈10.7C rate).

Featuring rapid charging (4.2A full charge in 1.5 hours) and an ultra-wide operating temperature range (charge: 0~45℃, discharge: -40~60℃), this cell excels in scenarios demanding extreme power output and durability, such as power tools and energy storage systems.

Core Features

1. 45A Continuous Discharge & 10C High-Rate Performance
   Designed for peak power demands, the P42A supports stable 45A continuous discharge (cut-off at 2.5V) with superior burst capability. Its discharge rate spans 0.2C to over 10C (45A/4.2A), ideal for heavy-load applications.
2. Extreme Temperature Resilience
   • Subzero Performance: Reliable operation at -40℃ with minimal capacity loss.
   • High-Temperature Stability: Maintains efficiency even at 60℃.
3. Fast Charging & Low Impedance
   • Rapid Charge: 4.2A standard charge completes in 1.5 hours; supports 8.4A fast charging (temperature-dependent).
   • Efficiency: Ultra-low impedance (10mΩ AC, 16mΩ DC) ensures 95%+ energy efficiency.
4. Longevity & Energy Density
   • Cycle Life: Retains ≥80% capacity after 500 cycles at 10A discharge.
   • Energy Density: 615Wh/L volumetric and 230Wh/kg gravimetric density for compact, lightweight designs.
5. Safety & Reliability
   Complies with UN38.3 standards, featuring a steel-can structure and passing rigorous safety tests (overcharge, short-circuit, thermal stress).

Applications

• Power Tools: Chainsaws, impact drivers, and industrial equipment.
• E-Bikes/Scooters: Combines high torque with extended range.
• Energy Storage: Reliable backup power for outdoor and off-grid systems.
