Samsung INR21700-30T Battery cell delivers a robust energy capacity of 3,000 mAh, maintaining an impressive 35 amp Continuous Discharge/Drain Rating consistently, and this performance is achieved without the need for temperature cuts. Even when subjected to a continuous discharge/drain of 30 amps, the cell's temperature rise is limited to a mere 67 degrees Celsius or 153 degrees Fahrenheit. This makes it suitable for powering devices up to 75 watts per cell while ensuring reliable operation over extended periods. The 30T excels in maintaining a stable output throughout prolonged use, making it an ideal choice for moderate wattage usage. It offers an exceptional equilibrium between High Capacity and Ultra-High Discharging/Drain capabilities, all without compromising on performance.


Samsung, renowned for its pioneering battery technology research and development, exemplifies its expertise through the 30T. Crafting a genuine 3,000 mAh capacity coupled with an unwavering 35 Amp True Constant Discharge Rating, all without invoking temperature restrictions that could strain the cell, showcases an impressive accomplishment. This cell instills genuine "Peace of Mind" by assuring users that their performance and safety requisites will not only be met but exceeded.


  • Rechargeable & Reusable

Invest in a rechargeable battery that will last for years to come– this battery can be recharged 250+ times.


  • High Discharge Rate

35A max continuous discharge rate for high-drain electronics, great for making battery packs for devices that require minimum discharge rates.


  • 3 Year Shelf Life

Stock up and store spare batteries with confidence– lithium ion batteries have a 3+ year shelf life, ensuring you always have a fresh replacement when you need it.


Notable Features

  • 3,000mAh capacity provides long runtimes for all your devices
  • Flat top terminal is perfect for use in making OEM battery packs
