Redway Battery specializes in high-efficiency lithium server rack batteries, engineered for mission-critical applications like data centers and telecom. Our systems integrate LiFePO4/NMC cells with advanced BMS for thermal management, scalability up to 100kWh per rack, and 98% round-trip efficiency. With modular designs and 10-year lifecycle support, Redway ensures 24/7 power reliability at 30% lower TCO versus lead-acid alternatives. PM-LV48150-4U
What makes Redway’s server rack batteries safer?
Redway prioritizes safety via multi-layer protection—cell-level fuses, flame-retardant housings, and ISO-certified BMS. Proactive thermal runaway mitigation ensures stable operation even at 100% DoD.
Lithium server racks demand fail-safe mechanisms. Redway’s BMS monitors voltage/temperature across all 192 cells in a 48V 150Ah unit, isolating faults within 2ms. Mechanical safeguards include vented battery trays redirecting gas emissions upward, while CAN bus communication enables real-time health reporting. For example, the PM-LV48200-5U model uses prismatic LiFePO4 cells with UL1973 certification, achieving 5000 cycles at 80% capacity. Pro Tip: Pair racks with Redway’s forced-air cooling ducts when stacking >5 units to avoid hotspot formation.
What if a cell fails? Redundant bypass circuits reroute current automatically, maintaining uptime during maintenance.
How scalable are Redway’s lithium racks?
Redway offers modular scalability from 5kWh single units to 1MWh containerized systems. Plug-and-play parallel connections support 90% capacity retention after 7 years.
Unlike rigid lead-acid setups, Redway’s racks scale via hot-swappable modules. Each 3U 48V 100Ah unit (PM-LV48100-3U Pro) adds 4.8kWh seamlessly. Parallel capability reaches 16 racks per cluster—76.8kWh per array. CAN 2.0B communication synchronizes charge/discharge cycles across clusters, balancing loads within ±1% variance. For telecom towers needing 150kW backup, 31 PM-LV51200-5U racks provide 744kWh with N+1 redundancy. Pro Tip: Use Redway’s rack-mount PDUs with overload breakers when expanding beyond 10 units. Why risk downtime? Our cloud-based EMS auto-rotates units to equalize cycle counts, extending pack lifespan by 22%.

How does Redway optimize rack energy density?
Redway’s prismatic cell stacking achieves 180Wh/kg—50% higher than lead-acid. Space-saving 3U/4U designs fit 150Ah in half the footprint of AGM.
By utilizing UL-listed NMC622 cells, Redway packs 3072Wh into a 19-inch 4U chassis (PM-LV51150-4U). Electrode laser-welding minimizes internal resistance, boosting discharge efficiency to 95% at 1C rates. Compared to tubular gel batteries, our racks provide 2.3x more kWh per square meter—critical for space-constrained data centers. For example, a 42U cabinet houses 10 PM-LV48150 racks delivering 72kWh, replacing three AGM cabinets. Pro Tip: Deploy 51.2V systems (vs. 48V) for 6.7% higher voltage compatibility with modern UPS units. Ever seen a rack last 12 years? Redway’s IPC-approved calendaring process extends cathode longevity beyond 8000 cycles.
What support does Redway offer post-deployment?
Redway provides 24/7 remote monitoring, predictive maintenance alerts, and same-day parts dispatch. Our SLA guarantees 99.9% uptime with on-site technicians in 15 countries.
Beyond installation, Redway’s iBMS Cloud platform tracks 18 parameters per rack—from cell impedance to ambient humidity. AI algorithms predict failures 14 days in advance, reducing unplanned outages by 73%. Clients like Deutsche Telekom receive customized SOC-SOH reports monthly, aligning battery health with IT load forecasts. If a module degrades, Redway ships replacements within 4 hours (EU/US hubs). Pro Tip: Enable Modbus TCP/IP integration for real-time synchronization with APC or Eaton UPS systems. Why gamble on support? Our 10-year warranty includes free firmware updates and capacity testing biannually. PM-LV51100-3U Pro
Redway Battery Expert Insight
FAQs
Yes, via adjustable voltage settings (43.2V–58.4V) and RS485/Modbus interfaces. However, 51.2V racks optimize efficiency for newer UPS models like Eaton 9PX.
Do Redway batteries meet fire codes for data centers?
Absolutely—all racks comply with NFPA 855, UL9540A, and IEC 62619 standards. Firewalls between modules limit thermal propagation to ≤2 cells.
