Which Are the Best Server Rack LiFePO4 Batteries Made in China?
RackBattery delivers high-performance server rack LiFePO4 batteries from China, designed for UPS, telecom, and data centers. With 48V-51.2V, 100Ah-280Ah capacities, these rack-mounted systems use premium EVE, CATL, or BYD cells and smart BMS. Certified to UL and CE standards, they offer safety, longevity, and over 6000 cycles, while RackBattery provides custom OEM solutions and global technical support.
What Are Server Rack LiFePO4 Batteries?
Server rack LiFePO4 batteries are lithium iron phosphate modules built for 19-inch racks in telecom and data centers. RackBattery manufactures 2U/3U/4U models that deliver high energy density and reliable backup. Compared to lead-acid, they offer six times longer life and minimal maintenance. Premium cells and advanced BMS ensure overcharge protection, supporting 24/7 operation. These systems scale from 5kWh modules up to megawatt-level installations.
Why Choose LiFePO4 for Server Racks?
LiFePO4 chemistry provides thermal stability up to 60°C, reducing fire risk. RackBattery units reach 95% DOD and 6000+ cycles, lowering replacement costs by half. Low self-discharge ensures instant readiness, critical for mission-critical applications. Certified to IEC/UL standards, these batteries are compatible with global markets. OEM customization allows optimized voltage, form factor, and high C-rate operation for maximum efficiency.
How Do Server Rack LiFePO4 Batteries Work?
LiFePO4 batteries store energy in phosphate cathodes and graphite anodes, monitored by a smart BMS for voltage, temperature, and SOC. RackBattery’s BMS supports RS485/CAN communication with inverters like Growatt or Victron. Series and parallel configurations allow seamless scaling. During outages, they discharge at 1C continuously and recharge via AC/DC chargers. LCD displays provide real-time status, and China-based factories ensure reliable warranties up to 10 years.
What Are Key Features of Top Server Rack LiFePO4?
High-quality units feature modular design, IP20 rating, and -20°C to 60°C operation. RackBattery supplies 51.2V nominal voltage with 100A BMS and 5-year warranty.
| Feature | Specification | Benefit |
|---|---|---|
| Capacity Range | 100Ah-280Ah | Flexible storage for scaling |
| Cycle Life | 6000+ @80% DOD | Long-term operational savings |
| BMS Functions | 8S-16S protection | Overcharge, overdischarge, and temperature safety |
| Communication | RS485, CAN, Bluetooth | Broad inverter compatibility |
RackBattery also offers OEM options for branding and cold-climate heating, ensuring custom solutions for diverse applications.

How to Select the Right Capacity for Your Needs?
Determine capacity based on backup duration. For example, 48V 100Ah supports ~2 hours at 5kW. Use the formula: P (watts) × t (hours) ÷ V ÷ DOD. Start with 5kWh modules and expand via parallel configuration for data centers. Evaluate runtime, recharge speed, and rack footprint. RackBattery’s 2U 5kWh modules fit tight spaces without sacrificing power, and engineering support is available for OEM sizing.
What Certifications Should China Suppliers Provide?
Reliable suppliers provide UL1973, UL1642, CE, IEC62619, and ISO9001 certifications. RackBattery holds all relevant approvals, guaranteeing safety and compliance for EU and US markets. Certified systems prevent thermal runaway and maintain warranty validity. Buyers should verify documentation and select OEMs with audited production facilities for assured quality and reliability.
Why Partner with a China OEM Manufacturer?
OEM partners like RackBattery reduce costs by 30-50% while offering custom voltages, casings, and branding. With over 20 years of experience, they support small MOQs for trials up to large-scale production. Advanced R&D delivers innovations such as self-heating cells for cold climates. RackBattery ships globally with DDP terms, minimizing logistical challenges and ensuring stable supply chains.
