1. Longtime cycle life: Longlife cycle life, and good cycle consistency after combining into a battery PACK, effectively ensure the cycle life of pack battery pack.
2. Consistency: The initial performance is consistent with the cyclic attenuation of the assembled performance, which effectively ensures the stability and life of the battery pack.
3. Self-discharge performance: Good self-discharge performance, stable and consistent self-discharge of the battery cells before and after PACK, effectively ensuring the stability and life of the battery pack.
4. High rate performance: Suitable for high power output.
5. High-and-low temperature performance: High and low temperature performance is good, suitable for use in the field of emergency lights, outdoor low temperature and other environments.
6. Safety: Through the strict destructive testing, safety testing, national and regional standards and reports.
7. Sufficient goods: Convenient procurement and end customer delivery, stable and guaranteed.
