Description

The Samsung INR21700-50E with tabs 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 tabbed cell delivers excellent energy density and consistent performance.

Equipped with pre-attached tabs for easy integration into custom battery packs and welded assemblies, the 50E is optimized for energy storage rather than high-drain output. It is ideal for e-bikes, solar storage systems, backup power, and other applications where extended runtime is more important than maximum current output.
