Typical Highlights
Unparalleled Performance:
With a 4000mAh nominal capacity and up to 70A continuous discharge capability, the 40PL delivers an uncommon combination of sustained high output and extended runtime. 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.
Efficiency Redefined:
The EVE 40PL 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.
Caution:
- Don't use this battery in e-cigarettes, vaporizers, or similar devices.
- Don't mix old and new, or used and unused batteries.
