Advantages
General features of OptimumNano Lithium Iron Phosphate Battery(LiFePO4 Battery):
1. Long life cycle, no memory effect.
2. High C-Rate Discharge capability, can be fast charged.
3. High peak power available under high depth of discharge.
4. High energy density, small size, light weight.
5. Good performance in high/low temperature working condition.
6.100% safe / environmental friendly / maintenance free.
Why choose OptimumNano LiFePO4 batteries?
Comparing with other China energy suppliers who only begin to engage in this vocation one or two years ago, we are the one or two producers started to research and develop LiFePO4 BATTERY as early 2006 and had been the main supplier of the Shenzhen 26th Summer Unversiade New Energy Automitive Lithium Iron Phosphate Battery Power System.
In May 2008, we have finished the First Pure Electric Bus for Shanghai Expo Project.
Until now ,we have become famous Electric vehicle power battery supplier.
OptimumNano LiFePO4 Battery test - Performance test
OptimumNano engineers take some tests to know battery performance clearly. Those tests include the different C-rate discharge, battery performance in difference temperatures, fast charging, and cycle life curves.
OptimumNano LiFePO4 Battery test - Abuse test
Unlike LiMo2O4 or LiCoO2 batteries, LiFePO4 modular structure is very stable, thus LiFePO4 battery is very safe in mis-opertation and hard conditions, Here are some abuse tests, such as Over-charge performance, Over-discharge performance, Short-circuit performance in normal temperature, Acupuncture performance, Thermal Shock safe performance etc.
OptimumNano Battery quality control method
8conformity:make sure the battery stability and long lifetime
