Samsung 58E 21700 5330mAh 10.7A Battery

Key Features 5330mAh High Capacity: Standard discharge capacity of ≥5330mAh at 0.2C to 2.5V, with a rated discharge capacity of ≥5170mAh at 1C — delivering reliable, high-energy output for extended-runtime applications. 20Wh Energy Output: Typical energy class of 20.0Wh per cell, positioning the 58E as one of the highest-energy cylindrical 21700 cells in its class. Stable Continuous Discharge: Maximum continuous discharge of 2C / 10.7A, optimized for energy-dense applications where sustained, controlled current draw is the primary design requirement. Low Impedance Design: Initial AC impedance of ≤15mΩ at 1kHz after standard charge for efficient energy transfer and consistent performance across the discharge cycle. 500-Cycle Durability: Retains ≥4136mAh capacity after 500 cycles under 0.5C charge and 1C discharge conditions, ensuring reliable long-term performance in professional battery pack applications. Overview The Samsung 58E is a high-capacity cylindrical 21700 lithium-ion cell engineered for energy-focused applications where maximum runtime and long-term reliability are the primary design objectives. Delivering a standard discharge capacity of ≥5330mAh at a nominal voltage of 3.64V, the 58E achieves a typical energy output of 20.0Wh per cell — among the highest available in the 21700 format. Its maximum continuous discharge rating of 2C / 10.7A makes it well suited to applications with moderate, sustained current requirements, where energy density takes priority over peak discharge capability. An initial AC impedance of ≤15mΩ supports efficient energy delivery with minimal resistive losses, and a rated cycle life of ≥4136mAh after 500 cycles under standard charge and discharge conditions ensures dependable performance over extended service. The 58E is an unprotected cell intended for integration into professionally engineered battery pack assemblies with appropriate protection circuitry and spot-welded interconnects — direct soldering to the cell is not recommended.
