Balanced Capacity with Rapid Charging Performance. Your portable power applications demand reliable energy storage with efficient recharge cycles. Our PK Cell ICR18650 delivers genuine 3000mAh capacity with 4-hour fast charging capability and verified 300+ cycle lifespan for sustained performance in power banks, LED lighting, and DIY battery projects.

As battery specialists since 2010, we've supplied thousands of 18650 cells to builders who prioritize consistent specifications over inflated marketing claims. Our precision-manufactured ICR18650 features authenticated 3000mAh typical capacity (2850mAh minimum), 0.5C standard charging rate, and wide operating temperature tolerance (-20°C to 60°C discharge) - engineered for enthusiasts and professionals who demand verified performance data in portable power and lighting applications.

PK Cell ICR18650 3000mAh Excels in These Applications:

• Portable Power Banks: Ideal for 10,000-50,000mAh USB power banks delivering 2-3A output where 4-hour charging cycle supports daily use patterns - common configurations include 3S2P (11.1V 6Ah) and 4S3P (14.8V 9Ah)
• High-Performance Flashlights: LED flashlights and tactical lights drawing 1-3A continuous with multi-hour runtime requirements - delivers consistent voltage curve throughout discharge for stable brightness levels
• Portable Electronics: Custom battery solutions for portable speakers, camping equipment, and mobile workstations where 3000mAh provides adequate capacity without space or weight penalties of larger cells
• DIY E-Bike Packs (Light Duty): Suitable for assisted pedaling systems with moderate power demands (250-500W) - typical 10S4P configuration (36V 12Ah) or 13S3P (48V 9Ah) for urban commuting applications under 15 miles
• Solar Charging Systems: Small off-grid solar setups and portable solar generators where daily cycling benefits from faster 4-hour recharge capability compared to higher-capacity alternatives requiring extended charge periods

Technical Compatibility Considerations:

Standard 18650 dimensions ensure universal compatibility with battery holders, spacers, and BMS systems designed for cylindrical cells. ICR chemistry characteristics optimize energy density for applications under 1.5C discharge rate - for loads exceeding 4.5A continuous per cell, consider INR chemistry alternatives with higher discharge ratings.

Critical Lithium-Ion Safety Parameters

• Overcharge Prevention Required: BMS must disconnect charging at 4.2V maximum - continued charging above 4.25V causes electrolyte decomposition, internal pressure buildup exceeding safety vent ratings, and potential thermal runaway events
• Discharge Protection Essential: Load disconnect at 2.5V minimum prevents copper dissolution from anode current collector - over-discharge below 2.3V creates permanent internal resistance increase and capacity degradation exceeding 20%
• Thermal Management Mandatory: Multi-cell packs require temperature monitoring between parallel groups - heat generation during 3A+ discharge in restricted airflow conditions can exceed safe operating limits within 15-20 minutes continuous use
• Short Circuit Safeguards: Insulating spacers and proper cell wrapping prevent accidental terminal contact - short circuit current can reach 30-50A instantaneously, generating sufficient heat to ignite PVC wrapping and compromise adjacent cells

We document these safety requirements transparently because proper lithium-ion handling protects both builders and end-users. Battery pack construction demands technical knowledge and appropriate safety equipment.
