The EVE 21700 50E lithium-ion battery cells pack a powerful punch, boasting a nominal capacity of 5000mAh. This impressive energy density ensures that the devices and vehicles they power can run for longer periods between charges, making them an attractive choice for applications demanding reliable and extended runtime.
Uncompromising Safety and Performance
These cells are engineered to deliver exceptional performance while prioritizing safety. With a nominal voltage of 3.65V and a cycle life of up to 1000 cycles, the 21700 50E cells provide reliable and consistent power throughout their lifespan. The low AC-IR (internal resistance) of ≤20mΩ further contributes to their efficiency and responsiveness, ensuring smooth and stable operation.
Versatile Charging and Discharging
The 21700 50E cells are designed with user-friendly charging and discharging parameters. The end-of-charge voltage is set at 4.2V, with a recommended end-of-charge current of 100mA. For discharging, the cells can safely operate down to 2.5V, making them suitable for a wide range of applications. The standard charging current of 1000mA and the maximum continuous charge current of 2500mA provide flexibility and fast-charging capabilities, while the standard discharge current of 1000mA ensures consistent and reliable power delivery.
Compact and Lightweight Design
Measuring just 21.15±0.10mm in diameter and 70.15±0.15mm in height, the 21700 50E cells boast a compact and space-efficient design. With a weight of 71g, these cells offer an excellent power-to-weight ratio, making them an ideal choice for applications where size and weight are crucial factors, such as electric vehicles and portable electronics.
Conclusion
As the data source indicates, these 21700 50E cells were developed and tested in EVE’s own laboratories, ensuring the highest standards of quality and reliability. EVE’s decades of experience in the battery industry are reflected in the careful engineering and attention to detail that have gone into the design of these cells, making them a trusted choice for a wide range of applications.
