Features of the 48V rackmount battery module
Performance Benefits
High level of security
The 48V rack-mount battery module, represented by lithium iron phosphate batteries, does not burn or explode even under extreme conditions, making it ideal for scenarios that require stable power supply for a long time. For example, in data centers, data security and business continuity can be ensured, avoiding data loss and business interruption caused by battery security issues.

Long cycle life
The cycle life of lithium iron phosphate batteries is thousands of times, which means that 48V rackmount battery modules can work stably for a long time, greatly reducing the frequency of replacement and maintenance costs. For example, some 48V rack-mounted battery modules used in communication base stations can maintain good performance after multiple charge-discharge cycles.

High energy density
These battery modules have a higher energy density and are smaller, allowing them to be easily integrated into rack-mounted devices while reducing overall weight. For example, the 48V50AH lithium iron phosphate battery LD4850pro can not only provide sufficient power reserves, but also flexibly adapt to a variety of equipment needs, whether it is a small server, network communication equipment, or a large data center, it can easily do the job.

Design features:
Modular design
The standard 19-inch rack mount is easy to install and maintain, and can flexibly combine multiple batteries according to actual needs to build energy storage systems of different scales. For example, in some scenarios where energy storage capacity needs to be expanded, the number of battery modules can be easily increased

Application flexibility
Strong adaptability
It can be adapted to a variety of devices and application scenarios. For example, in different fields such as telecom base stations, solar energy systems, and data centers, you can choose the right 48V rack-mounted battery module according to your specific needs to provide stable power support for the equipment
