2. Advantages fully displayed

(1) Safe and Reliable
The rack-mounted lithium iron phosphate battery pack has undergone rigorous safety testing and has shown outstanding performance in terms of safety. Compared to other types of batteries, such as ternary lithium batteries, LiFePo4 batteries have higher thermal stability and high temperature resistance. By using lithium iron phosphate as the positive electrode material, the risk of thermal runaway is lower, making it less likely to experience thermal runaway even in high temperature or overcharged states, greatly reducing the risk of fire and explosion and providing users with reliable safety assurance. For example, even in the event of a severe collision during actual use, the battery pack will not explode, ensuring the safety of equipment and personnel in various application scenarios.

(2) Long Lifespan
The cycle life of the 48V rack-mounted lithium iron phosphate battery pack is long, which is one of its significant advantages. The cycle life of a single cell exceeds 8000 cycles, while the cycle life of a group exceeds 6000 cycles, compared to lead-acid batteries which typically have a cycle life of around 300 cycles, with a maximum of about 500 cycles. Such a long cycle life means that under the same conditions of use, the battery pack's lifespan is several times that of lead-acid batteries. For example, in a conventional 48V model, the cycle life of a lithium manganese battery pack is over 600 cycles, while the cycle life of a lithium iron phosphate battery pack can exceed 6000 cycles, making the lifespan advantage of the lithium iron phosphate battery pack more apparent. This allows users to reduce the frequency of battery replacement and lower usage costs over the long term.

(3) Excellent Performance
a. Good High Temperature Performance: The rack-mounted lithium iron phosphate battery pack has good high temperature performance. Its thermal peak can reach 350°C - 500°C, while lithium manganese and lithium cobalt only reach around 200°C. It has a wide operating temperature range (-20°C - +75°C) and high temperature resistance characteristics, allowing the battery pack to operate stably in high temperature environments and be suitable for various complex working environments.
b. Large Capacity: The battery pack has a larger capacity than ordinary batteries (such as lead-acid). For example, a 48V280Ah lithium iron phosphate battery pack can provide longer power support for equipment.
c. No Memory Effect: The rack-mounted lithium iron phosphate battery pack has no memory effect, allowing the battery to be used as needed without having to fully discharge before recharging. This brings great convenience to users, as they do not have to worry about the memory effect affecting the battery's performance and lifespan.
d. Lightweight: The volume of a lithium iron phosphate battery with the same capacity as a lead-acid battery is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery. This gives the rack-mounted lithium iron phosphate battery pack a significant advantage in applications where weight is important, such as communication base stations and RVs.
e. Environmentally Friendly: The battery is generally considered to be free of heavy metals and rare metals, non-toxic, non-polluting, and compliant with European RoHS regulations, making it an absolutely green and environmentally friendly battery. In today's increasingly environmentally conscious world, the environmental characteristics of the rack-mounted lithium iron phosphate battery pack make it the preferred choice for many users.

(2) Rack-mounted Design
1. Support for parallel expansion: The 48V lithium iron phosphate battery rack-mounted battery pack adopts a rack-mounted design, supporting parallel expansion. This means that users can parallel multiple battery packs together according to their actual needs to increase the system's capacity and output power. For example, in commercial energy storage systems, users can gradually increase the number of battery packs according to the growth of energy storage needs, achieving system expansion. This flexible design allows the battery pack to adapt to different scale application scenarios, improving the system's scalability.
2. Built-in MBS, achieving zero maintenance: The battery pack is equipped with a Management and Balancing System (MBS) that achieves zero maintenance. The MBS can monitor the status of the battery pack in real-time, including parameters such as voltage, current, temperature, etc., and balance the batteries to ensure that each cell works in optimal condition. At the same time, the MBS also has protection functions such as overcharging, over-discharging, overcurrent, and temperature, effectively preventing the battery from being damaged due to abnormal situations. This zero maintenance design greatly reduces user operating costs and maintenance difficulties, improving the system's reliability and stability.
3. Low lifecycle cost: Due to the advantages of long life, high energy density, and low maintenance costs of the 48V lithium iron phosphate battery rack-mounted battery pack, its lifecycle cost is relatively low. Compared to traditional lead-acid batteries, although the initial investment in lithium iron phosphate batteries is higher, their lifespan is several times that of lead-acid batteries, and they do not need frequent battery replacements during use, reducing maintenance costs and downtime. In addition, high energy density battery packs can reduce the volume and weight of the system under the same capacity requirements, reducing transportation and installation costs. Therefore, from the perspective of the entire lifecycle, the 48V lithium iron phosphate battery rack-mounted battery pack has a higher cost-effectiveness.
(3) Intelligent Management

1. Equipped with high-performance BMS: The 48V lithium iron phosphate battery rack-mounted battery pack is equipped with a high-performance Battery Management System (BMS). The BMS has protection functions such as over-discharge, overcharge, overcurrent, temperature, etc., ensuring the safety of the battery. For example, when the battery is overcharged, the BMS will automatically cut off the charging circuit to prevent the battery from being damaged due to overcharging; when the battery is over-discharged, the BMS will automatically cut off the discharge circuit to prevent the battery from affecting its lifespan due to over-discharge. At the same time, the BMS can monitor the status of the battery in real-time, such as voltage, current, temperature, etc., and provide this information to the user, allowing the user to understand the battery's operating status at any time.
2. Multiple protection functions: In addition to over-discharge, overcharge, overcurrent, temperature protection functions, the BMS also has short circuit, reverse charging protection functions. The short circuit protection function can quickly cut off the circuit when the battery experiences a short circuit, preventing safety accidents such as fires caused by short circuits. The reverse charging protection function can prevent the battery from being reverse-charged during the charging process, protecting the safety of the battery. The existence of these protection functions makes the battery pack safer and more reliable during use.
3. Automatic charge and discharge management: The BMS can achieve automatic charge and discharge management, with monitoring units automatically measuring the charge and discharge current of the battery, and managing float and equal charge of the battery. When the battery is low on power, the BMS will automatically start the charging mode to charge the battery; when the battery is full, the BMS will automatically stop charging to prevent overcharging. During discharge, the BMS will adjust the discharge current automatically according to the battery's power level and load conditions, ensuring a safe and stable discharge process. In addition, the BMS also has a secondary power-off function, which will issue an alarm when the battery voltage is below the warning value; when the battery voltage is too low, it will automatically power off to protect the battery system.
