Custom BBU and UPS Battery Solutions for Data Centers and Telecom
What Are BBU and UPS Batteries?
Quick Answer: BBU batteries provide short-duration backup power close to servers, telecom equipment, or network nodes, while UPS battery systems support broader centralized loads. The correct solution depends on output voltage, peak power, backup duration, communication protocol, thermal design, and system architecture.
A Battery Backup Unit (BBU) is a localized DC backup system designed to maintain critical equipment during a short power interruption or until another power source becomes available. Rack-level BBUs for AI servers prioritize rapid response, high power density, and close integration with the server power architecture. Telecom BBUs commonly use 48V-class battery modules to support base stations, fiber networks, and remote communication nodes.
A UPS battery system supports an uninterruptible power supply that protects larger centralized loads such as server rooms, industrial controls, security systems, and medical infrastructure. Runtime, output architecture, redundancy, and power conditioning requirements differ from those of a rack-level BBU.
Large Power develops custom lithium battery solutions with application-specific cell chemistry, enclosure design, connectors, thermal management, and an integrated Battery Management System (BMS). Final voltage, capacity, discharge capability, and testing requirements are defined according to the customer’s equipment and target market.

Why Choose Our Custom BBU and UPS Battery Solutions?
Reliable backup power for critical infrastructure and always-on operations
Large Power develops BBU and UPS battery packs around the required voltage, peak power, backup duration, space, thermal environment, communication interface, and maintenance strategy. Performance and compliance targets are defined for each project rather than assumed across every battery configuration.
Fast Response for Critical Loads
Our BBU and UPS battery systems can be engineered for rapid response during outages or voltage disturbances. Transfer behavior and ride-through time depend on the complete power architecture, including the battery, BMS, charger, converter, and load profile.
Application-Specific Energy and Power Design
Cell chemistry and pack architecture are selected according to the required balance of energy density, discharge power, service life, temperature range, and installation space. NMC may suit compact high-power rack-level BBUs, while LiFePO4 can support applications that prioritize thermal stability and longer cycle life.
Smart BMS and Remote Monitoring
Each system can integrate a smart Battery Management System (BMS) for cell monitoring, balancing, temperature protection, fault reporting, and state estimation. Communication options may include CAN, RS485, I2C, or other interfaces required by the host equipment.
Mechanical Integration and Project-Based Compliance
We support application-specific voltage, capacity, enclosure, connector, mounting, thermal management, and communication requirements. Applicable testing and certifications, such as UN 38.3, IEC 62619, UL standards, CE, or RoHS, are evaluated according to the final design, target market, and customer requirements.

BBU and UPS Battery FAQ
These answers cover the main engineering decisions for rack-level BBU, telecom backup, and centralized UPS battery projects.
What is the difference between a BBU and a UPS battery system?
A BBU is usually installed close to a server rack, telecom node, or other specific load to provide localized DC backup. A UPS supports broader centralized loads and normally includes power-conversion and power-conditioning functions. The two systems may complement each other rather than serve as direct replacements.
How long should a BBU support the connected equipment?
Required backup duration depends on the system architecture. Some rack-level BBUs provide only enough ride-through time to bridge a short interruption or complete a controlled transition, while telecom and UPS batteries may require longer operation. Runtime must be calculated from load power, battery energy, conversion efficiency, temperature, aging margin, and end-of-life capacity.
Should a BBU use NMC or LiFePO4 cells?
NMC offers higher energy density and may suit compact, high-power rack-level BBUs. LiFePO4 provides strong thermal stability and longer cycle life for installations with more available space. Cell selection should also consider peak current, operating temperature, service-life target, enclosure design, and charging strategy.
Which communication protocols can a smart BBU support?
Depending on the host equipment, the BMS can be designed to support CAN, RS485, I2C, SMBus, UART, or other communication interfaces. The protocol, data map, fault logic, and state-of-charge reporting requirements should be confirmed during system integration.
What testing and certifications may apply to BBU and UPS batteries?
Requirements depend on the battery design, installation, transport method, and target market. Projects may require UN 38.3 transport testing and safety evaluation under standards such as IEC 62619 or applicable UL requirements. CE, RoHS, EMC, enclosure, and system-level tests may also apply. Compliance should be defined for the final product rather than assumed from the battery chemistry alone.
