Introduction of 48V Rack Mounted Lithium Battery Energy Storage Equipment Product Information Overview In the market, there are many 48V rack mounted lithium battery energy storage products to choose from. Scope of application Everyday electronic devices are suitable for cameras, e-books, tablets, portable speakers, digital photo frames, power banks, cordless phones, portable projectors, MP3/MP4 players and other devices. 

These devices typically require a stable power supply, and 48V rack-mounted lithium batteries can meet their power needs to keep them up and running2. Transportation and special equipment can be used in electronic cigarettes, bicycles, electric motorcycles, scooters, balance bikes, drones, model airplanes, power tools and other fields. In addition, it is also widely used in industries with high requirements for power supply stability and performance, such as communications, medical, aircraft, ships, aerospace technology, military industry, transportation equipment, security equipment, etc., especially for equipment that requires high current discharge and high capacity. 

Energy is also commonly used in energy equipment such as energy storage, solar energy, wind energy, and thermal energy. For example, as a solar photovoltaic energy storage battery, it is used to store electrical energy in the solar system to achieve effective use of energy; It can also be used for energy storage of communication base stations to ensure that the base station can continue to work when the mains power is interrupted. 

Product Features Performance Parameters Standard Capacity: The standard capacity of different products is different, such as the nominal capacity of 2000 - 3500mAh, there are also specifications such as 51.2V100AH, and the instantaneous discharge current can reach more than 100A (amperes)24. Internal resistance: The internal resistance of some products is ≤ 0.4mΩ, which can reduce the loss of electrical energy in the process of transmission and improve the efficiency of the battery4. 

Battery characteristics Accurate pairing: imported batteries can be perfectly paired, and the voltage, internal resistance, capacity and other parameters of all batteries are relatively consistent, which ensures the overall performance and stability of the battery pack. High safety: The battery made of lithium iron phosphate has good thermal stability and safety, and can effectively reduce the risk of fire and explosion during use. 

Precautions for transportation and use Transportation Due to the new requirements of air transportation, the factory power of the battery will not be higher than 30%, and the voltage must be charged when it is used for the first time. Charging requirements: You need to choose a lithium battery charger with corresponding parameters, and do not arbitrarily use the charger of other rechargeable batteries such as nickel-metal hydride and nickel-cadmium. For example, a 48V battery needs to be charged with a charger that matches 48V2. 

Use of protection board: Lithium batteries need to be equipped with protection plates to prevent overcharging and overdischarging. If some people do not add a protective plate when using the flashlight, it will damage the battery and cannot be charged, and the battery with too low voltage (below 1V) or no voltage should not be used again2. Processing restrictions: Once the battery cell is processed, it will not accept returns, and it is necessary to pay attention to the control of insulation and welding temperature during spot welding and welding to avoid damage to electricity
