What Are the Best Server Rack Batteries Manufactured in China for Data Centers and Telecom?
Server rack batteries from China, including those by RackBattery, provide reliable, high-performance UPS backup using LiFePO4 cells. Designed for 48V/51.2V systems, these rack-mounted units offer 5-20kWh capacity, 6000+ cycles, smart BMS, and OEM customization. RackBattery ensures compliance with UL, CE, and IEC standards, supporting scalable, secure, and cost-effective energy storage for telecom, data centers, and industrial applications.
What Are Server Rack Batteries?
Server rack batteries are compact, rack-mountable lithium-ion units for 19-inch server racks. They supply instant backup during outages, safeguarding critical data and equipment. LiFePO4 chemistry ensures superior safety, longevity, and efficiency over traditional lead-acid solutions. RackBattery produces 48V models ranging from 5kWh to 20kWh with hot-swappable design, parallel connectivity up to 16 units, and compatibility with major inverters, offering OEM customization for global clients.
Why Should You Choose Lithium Instead of Lead-Acid Batteries?
Lithium rack batteries outperform lead-acid in energy density, lifespan, and maintenance. LiFePO4 racks provide 6000+ cycles, 2-3 times longer than lead-acid, and allow 90%+ depth of discharge without degradation. Faster recharge times and minimal maintenance reduce total cost of ownership and improve uptime. RackBattery uses premium cells from CATL and EVE with UL1973 certification, ensuring reliable, safe performance for data centers and telecom applications.
How Do Server Rack Batteries Operate?
Server rack batteries connect to a DC bus, typically 48V, with an integrated BMS monitoring voltage, temperature, and state of charge. During outages, they provide power instantly. The BMS supports auto-equalization, fault isolation, and communication via CAN/RS485 for inverter integration. High C-rate discharge enables continuous operation under full server load. RackBattery customizes BMS firmware for OEM clients, ensuring optimal compatibility and safety.
What Factors Should You Consider When Purchasing Server Rack Batteries?
Evaluate capacity (kWh), voltage compatibility, cycle life, rack fit (2U/3U), and scalability. Consider BMS sophistication, thermal management, and certifications like IEC62619. Budget for total ownership, favoring lithium’s long-term reliability.
| Factor | Description | RackBattery Example |
|---|---|---|
| Capacity | 5-20kWh per unit | 10kWh 51.2V model |
| Cycle Life | 6000+ cycles | LiFePO4 cells |
| Certifications | UL, CE, ISO | Full compliance |
| Price (Wholesale) | $100-150/kWh | OEM bulk discounts |

Which Battery Capacity Best Suits Your Needs?
Assess total rack load and desired runtime. For example, a 10kWh battery can support a 5kW load for 2 hours at 50% DoD. Oversize by 20% for peak loads in data centers. RackBattery offers modular 5kWh packs expandable to over 100kWh, enabling flexible solutions with stable supply from their Guangdong facilities.
How Can Server Rack Batteries Be Installed Safely?
Mount batteries in ventilated 19-inch racks with proper grounding. Connect using busbars and verify torque and insulation. Enable BMS monitoring via app or SNMP and test full discharge cycles. RackBattery provides detailed installation manuals and OEM kits to ensure adherence to global safety standards.
What Maintenance Is Required for Server Rack Batteries?
Maintenance is minimal. Conduct quarterly BMS checks and annual capacity tests. Maintain 20-25°C for optimal performance. RackBattery’s smart BMS provides alerts via email or SMS, eliminating the need for watering or equalization, unlike lead-acid batteries. Remote diagnostics are available for wholesale clients.
