Description

The Samsung INR21700-50E is a high-capacity rechargeable lithium-ion battery designed for applications requiring long runtime and reliable energy delivery. With a nominal voltage of 3.6V and a capacity of 5000mAh, this flat top cell offers excellent energy density and consistent performance.

Unlike high-drain cells, the 50E is optimized for capacity over current output, making it ideal for energy storage systems, e-bikes, flashlights, and battery packs where extended runtime is more important than extreme power output. Its flat top design makes it suitable for battery pack assembly and compatible devices.
