Samsung 50S 21700

Samsung 50S 21700 is a high-quality lithium-ion 21700 battery cell from Samsung, designed for high-performance applications where both capacity and current delivery matter. It has a nominal capacity of around 5000 mAh and a nominal voltage of about 3.6 V, with dimensions of approximately 21 mm diameter and 70 mm length, providing a lot of energy in a compact size. The cells are rated for a continuous discharge current up to ~20 A, with higher short-term pulse currents, making them suitable for powerful e-bikes, electric scooters, power tools, and other high-drain devices. With low internal resistance (<20 mΩ), they heat up less under load. Samsung 50S cells are widely used in battery packs assembled in series and parallel configurations, allowing flexible setups for specific needs and usage styles.
