designed for applications that need a practical mix of runtime, current capability, compact size, and pack-building flexibility. This Shopify-ready page summarizes the live product listing and Samsung SDI specification into a technical, chart-heavy layout for customers comparing voltage behavior, rate capability, cycle life, thermal limits, and fitment. 3000mAh Class Capacity 15A Continuous Discharge 4A Rated Charge 3.6V Nominal Voltage 18650 Form Factor Unprotected Flat Top 3000mAh class capacity 2950mAh minimum capacity 15AMax Continuous Discharge 4ARated Charge Current ≤26mΩInitial AC Impedance 18.4 × 65.0mmMax Cell Envelope Samsung 30Q 18650 3000mAh 15A Battery The Samsung INR18650-30Q sits in the balanced high-drain category. It offers more capacity than many ultra-power-focused 18650 cells while still providing a 15A continuous discharge rating. That makes it useful for flashlights, custom packs, moderate power tools, robotics, portable equipment, and other designs that require stable 18650 performance without moving to a lower-capacity cell. In practical design terms, the 30Q is best viewed as a capacity-forward high-drain cell: strong 3.0Ah-class runtime with enough current support for medium-to-high drain devices. For engineering calculations, use 2950mAh minimum capacity, 2900mAh rated 10A discharge capacity, and 15A maximum continuous discharge at 25°C. Design note: the simplified charts below are presentation-oriented engineering visuals built from the published specification and test conditions. They are meant for product-page comparison and pack-planning guidance, not as a substitute for full validation testing in the final application.
