In the world of lithium-ion batteries, EVE Energy has established itself as a leader in providing high-performance and reliable solutions for a wide range of applications. One of their standout offerings is the 21700 cylindrical cell, the 21700 50E lithium battery. This blog post delves into the specifications of this battery, highlighting its design strengths and potential use cases.
Understanding the Specifications of the 21700 50E Battery
The specifications of a battery give insight into its performance, safety, and suitability for various applications. Here, we explore the key specs of the EVE 21700 50E model.
End-of-Charge Voltage: 4.2V
The end-of-charge voltage is a critical specification as it determines the maximum voltage to which the battery should be charged. For the 21700 50E, this voltage is set at 4.2V. Charging beyond this voltage can stress the battery, potentially leading to overheating and reduced lifespan. A voltage of 4.2V ensures optimal energy density while maintaining safety and longevity.
End-of-Charge Current: 100mA
This specification indicates the current level at which the charging process should terminate. The lower end-of-charge current of 100mA for the 21700 50E ensures that the battery is gently topped off, reducing the risk of overcharging and enhancing the overall battery health. This slow finishing charge helps in stabilizing the battery cells and maximizing their lifespan.
End-of-Discharge Voltage: 2.5V
The end-of-discharge voltage is set at 2.5V, which is a common cutoff for many lithium batteries to prevent excessive depletion that can harm the battery’s internal chemistry. Discharging below this level can cause irreversible damage, reducing both the capacity and cycle life of the battery. By setting this limit, EVE helps ensure that the battery remains within a safe operational range.
Standard Charging Current: 1000mA
The standard charging current is crucial for determining how quickly the battery can be charged. A 1000mA (1A) standard charge rate for the 21700 50E is an effective balance between charging speed and thermal management. This rate allows the battery to be charged efficiently without imposing high thermal stress, which can degrade the battery cells over time.
Conclusion
EVE’s 21700 50E lithium battery is a testament to the company’s commitment to innovation and quality. By understanding the specifications and recognizing the appropriate applications, users and manufacturers can maximize the potential of this battery, ensuring optimal performance and longevity. Whether for personal devices, transportation, or energy solutions, the 21700 50E offers a compelling choice for a reliable and efficient power source.
