Jiangsu OptimumNano Energy Co., Ltd. (hereinafter referred to as "Jiangsu OptimumNano") is a lithium battery business platform under China Aerospace Science and Technology Group. Jiangsu OptimumNano is headquartered in Gaoyou City, Jiangsu Province, and its main production base is located in Gaoyou Economic Development Zone, with a planned total area of 3,000 mu. It is planned to achieve a total production capacity of 50GWh by 2024, becoming the world's largest lithium iron phosphate cylindrical standard battery production base. Among them, the first phase of the project has a total construction area of 137,000 square meters, with 1 R&D pilot line and 7 fully automated cylindrical cell production lines, with a daily output of 420,000 large cylindrical cells and an annual production capacity of 5GWh.
1. Jiangsu OptimumNano ferro phosphate battery 32800 7.5Ah for byd home energy storage.
2. 7.5Ah Lithium ion Battery is designed for the replacement of the Lead-Acid batteries mainly used for power backup applications, can directly replace the Lead-Acid batteries by using the same standard shells. This series of LiFePO4 batteries Integrated with BMS, have fully protection features, such as over charging protection ,over discharging protection, over current protection and short-circuit protection etc. O’cell E2 series of LiFePO4 batteries with wide capacity range from 12V 4.5Ah to 12V 300Ah call fulfil almost all types of applications to replace existing Lead-Acid batteries.
