2) Advantages:

1, The key to battery quality is Material LiFePO4, Facilities, and technique.

----For LiFePO4, many suppliers use domestic materials: ( technically immature ), Price: $13000/t. But imported mature LiFePO4: Price: $20000/t

----For facilities like coating machine: Price (domestic): just several millions of USD. But price (imported) is Tens of millions USD

2, Technology: new energy star LiFePO4 Battery appear in 2005 worldwide. Japan, Korea, USA, China is the Pioneer. And LifePO4 battery, though be looked good by public, yet a newly rising field, few suppliers has

very mature techniques. Optimum in Shenzhen, the LiFePO4 Battery Centre, has produced Ni-Zn battery since 2002. and started producing LiFePO4 battery in 2006. 7 years\' practice win us rich Technology accumulation.

3, Safty: to a great extent, the safty of a battery depends on BMS. You know, many suppliers just produce battery module, and buy BMS. Though year\'s reseach. now we have developed our own BMS, of perfect compatibility

with our battery, That\'s to say, quality of battery module and also key part BMS are under our control, which receive very good feedbacks from our old customers in USA, Europe, etc.

4, Quality control: Optimum\'s powerful QC team strictly carry on 5 QC steps. Our CEO know very well, battery almost belong to \"dangerousproduct\". Quality is our life. We never \"green light\" defective products to our customers!

5, Service: for electric products especially battery:service, MF, technical support are more important. Generally, suppliers only offer 1 year warranty. We afford 2 years and technical support and free repair forever, for we fully understand,

what it means to customers if battery abnormal anytime. We already has dozens of service agency nationwide, and now plan to set offices worldwide to answer foreign customers\'s needs. Good neighbours Korea, Russia are prior.
