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.
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 - CLMT
OptimumNano adopts CLMT method to control the quality of Battery packs, the core factors like inner resistance, charge / discharge characteristics, available capacity would be considered in quality control procedures.
OptimumNano all in one solution, Battey pack + BMS + Charger
OptimumNano offer "Battery Pack + BMS + Charger ", as all in one solution. Our engineers would test / adjust all related components if customer needed. Like CAN BUS communication or on-off signal way details.
