Reliance RS50 70A 5000mAh Flat Top 21700 Tabless Battery - Wholesale Discount

Next Generation Tabless Battery Cell

The Reliance RS50 is a next-generation 21700 lithium-ion cell built around a tabless electrode architecture, significantly reducing internal resistance and improving thermal performance under load. This design minimizes current bottlenecks inside the cell, resulting in lower voltage sag, more uniform heat distribution, and improved efficiency during high-current charge and discharge operation.  

With a 5000 mAh nominal capacity and up to 70 A continuous discharge capability, the RS50 delivers an uncommon combination of sustained high output and extended runtime. 8A standard charge and 15A max charge current allows for extreme fast charging.  Its stable chemistry and robust construction make it well suited for high-drain pack builds, e-mobility systems, and demanding power applications where both performance and reliability are critical.
