The Samsung 30T 21700 battery is a powerhouse designed for high-drain applications, setting a benchmark in the world of lithium-ion cells. With an impressive nominal capacity of 3000mAh, this battery is engineered to provide the energy required by devices that demand substantial power output. The 30T excels in delivering high performance, offering a continuous discharge rating of 35A, making it an ideal choice for ultra-high drain devices. This makes it one of the top contenders for applications where a constant, reliable flow of energy is needed, such as in power tools, high-performance flashlights, and electric vehicles, among other demanding devices.

The true strength of the Samsung 30T lies in its remarkable discharge capabilities. With the ability to continuously output 35 amps without relying on temperature cutoffs, this battery can endure prolonged use under significant load without overheating or suffering from voltage sag. Even when pushed to 30 amps of continuous discharge, the battery only reaches a temperature of 67°C (153°F), which is a testament to its exceptional thermal management. This performance ensures that the Samsung 30T maintains its high power output while minimizing the risks of overheating, which can significantly affect the longevity and safety of many other batteries in similar applications.

Designed specifically for ultra-high discharging and draining devices that exceed 20 amps, the Samsung 30T truly shines when used in environments that require robust and sustained energy. In these conditions, the 30T’s voltage remains remarkably stable, with almost no sag in voltage until it reaches the manufacturer's specified limit. This stability ensures that devices powered by this battery continue to operate efficiently even during extended use, which is crucial for the performance of high-drain equipment. The Samsung 30T’s ability to hold its voltage and sustain power under heavy use makes it a top choice for those who need consistent, long-lasting energy, without the risks of premature voltage drops.

The battery’s capacity of 3000mAh provides a substantial energy reserve, ensuring that devices can run longer between charges. This makes the 30T ideal for applications that require extended operational periods, such as in power tools, e-bikes, and other high-drain devices. The nominal voltage of 3.6V, which is standard for many lithium-ion batteries, offers a reliable and stable power output for a wide range of devices. With a maximum voltage of 4.2V when fully charged and a discharge cutoff voltage of 2.5V, the 30T delivers a well-balanced power cycle, offering both high energy storage and efficient discharge capabilities.

At 68.2 grams in weight and with dimensions of 21.10mm in diameter and 70.20mm in length, the Samsung 30T fits the 21700 battery size profile, providing a compact yet powerful energy solution. The flat top design of the 30T makes it compatible with a broad range of devices, ensuring easy integration into different battery packs and equipment that require high-performance cells. This design, paired with its high discharge rate and reliable power output, makes the Samsung 30T a versatile choice for a variety of applications
