48V rack batteries for servers are available through specialized manufacturers and suppliers offering standard 5U/10KWH configurations with LiFePO4 chemistry for high energy density and thermal stability. Prices range from ¥2,600 to ¥9,080 for 100–200Ah units, with bulk discounts available. Key suppliers include Genixgreen, GSL ENERGY, and Highidea, providing solutions compatible with UPS systems, solar storage, and telecom infrastructure. Pro Tip: Verify rack dimensions and BMS protocols to ensure compatibility with existing server setups.

Where can I purchase 48V server rack batteries?
Primary vendors include industrial battery manufacturers like Genixgreen and GSL ENERGY, offering 48V LiFePO4 rack batteries in 100–280Ah capacities. Platforms like Alibaba and industry-specific distributors provide bulk purchasing options starting at ¥8,200 for 1,000+ units. Most suppliers ship globally from Guangdong or Jiangsu provinces with 2-day processing.
Deep Dive: Server-grade 48V rack batteries typically use 15S LiFePO4 configurations (48V nominal, 54.75V fully charged). For example, GSL ENERGY’s 48V 200Ah model delivers 9.6kWh, supporting 8–12 hours of runtime for mid-sized data centers. Key specs include ≥6,000 cycles at 80% DoD and IP30 enclosures. Pro Tip: Prioritize suppliers offering modular designs—parallel-ready systems like Highidea’s ETR series allow scalability without rewiring. However, mismatched internal resistances in parallel setups can reduce efficiency by 8–12%.
What technical specs define server-compatible 48V rack batteries?
Server applications require 5U/19-inch rack compliance, 45–60Hz output frequency, and pure sine wave inverters. Look for ≥130% overload capacity (e.g., Highidea’s 3kVA units handle 20-second surges) and RS232/SNMP communication for remote monitoring.
Deep Dive: Standard dimensions (310×438×88mm) ensure compatibility with server cabinets. Take Genixgreen’s ESS-9600—it integrates a 150A BMS with cell balancing ±20mV and over-temperature cutoffs at 65°C. For cold environments, Jiangsu-based GSO batteries include -20°C charging capability using electrolyte additives. Pro Tip: Avoid units without forced-air cooling if deploying in confined server rooms—passive thermal designs may overheat during 95%+ discharge cycles.
| Model | Capacity | Peak Power |
|---|---|---|
| GSL 48V 100Ah | 4.8kWh | 5kW |
| Highidea 3kVA | 10.24kWh | 7.2kW |
| Genixgreen ESS-9600 | 9.6kWh | 6kW |

FAQs
Only models with dual-bus BMS designs (e.g., SMI 48V series) allow module replacement without downtime. Standard units require full shutdowns during maintenance.
What’s the lead time for custom 48V server batteries?
Most Chinese suppliers require 15–25 days for non-stock configurations like 280Ah/14.33kWh units. Expedited production costs 18–22% extra.
