High Light Lithium 48v telecom batteryRack Mounted 48v telecom battery48V telecom backup batteries

The SOETECK SY-Li Series Rack-Mounted 48V Lithium Iron Phosphate (LiFePO4) Battery is a high-performance, space-efficient power solution built for modern critical power infrastructure, and a superior upgrade to conventional 48V lead-acid battery banks. Optimized for 19-inch standard server rack installations, it delivers reliable performance for data centers, telecom base stations, edge computing facilities and industrial UPS systems alike.

Equipped with premium automotive-grade LiFePO4 cells and an integrated intelligent BMS, it features a 48V nominal voltage (51.2V full charge) with configurable capacities of 100Ah to 500Ah, and allows parallel expansion up to 16 units for scalable energy storage needs. With an exceptional cycle life of 4000+ cycles (80% DOD), rapid 0.5C charging that recovers 80% capacity in 2 hours, and a completely maintenance-free design, it achieves a 50% TCO reduction compared to 48V lead-acid batteries across a 10-year service life. It also delivers dramatic space and weight savings, with 60% less rack footprint and a 70% lighter profile for streamlined deployment.

Product Features

Precision Motor
 

Intelligent BMS & Multi-Layer Safety Protection

Integrated high-precision BMS (Battery Management System) with real-time monitoring of cell voltage, current, temperature, and SOC (State of Charge). Provides multi-layer protection: overcharge/over-discharge protection (42V cut-off / 58.4V cut-off), overcurrent/short-circuit protection, overtemperature/undertemperature protection (-20°C to 60°C), and cell balancing to ensure uniform charging/discharging. Supports RS485/Modbus/CanBus communication for remote monitoring and control via central management systems.

 

Fast Charging & Wide Temperature Adaptability

Supports 0.5C fast charging (e.g., 50A charge current for 100Ah battery), recovering 80% capacity in 2 hours and 100% capacity in 3 hours (3x faster than 48V lead-acid). Operates reliably in extreme temperatures (-20°C to 60°C discharge, 0°C to 45°C charge), suitable for outdoor telecom base stations and harsh industrial environments. Low self-discharge rate (<1%/month at 25°C), no regular charging required during storage.

FAQ

 
1. What is the key difference between 48V rack-mounted lithium battery and 48V lead-acid battery?
48V lithium batteries outperform lead-acid in core metrics: (1) Cycle life: 4000+ cycles (80% DOD) vs. 800 cycles for lead-acid; (2) Energy density: 140Wh/kg vs. 45Wh/kg (70% weight reduction for same capacity); (3) Charging speed: 80% capacity in 2hrs vs. 8hrs for lead-acid; (4) Space efficiency: 60% less rack space; (5) Maintenance: Zero maintenance vs. regular watering/checks for flooded lead-acid. Lithium has higher upfront cost but 50% lower TCO over 10 years due to longer lifespan and lower operational costs.
2. What is the cycle life and service life of 48V rack-mounted lithium battery?
At 80% Depth of Discharge (DOD), cycle life is 4000+ cycles (retains ≥80% capacity); at 50% DOD (standby use), it extends to 6000+ cycles; at 100% DOD, cycle life is 2500 cycles. Under normal operating conditions (25°C, float charge voltage 53.5V), the service life is 10-12 years (2x longer than 48V AGM lead-acid). At 35°C, service life reduces to 8-9 years due to accelerated cell aging, but still 1.5x longer than lead-acid at same temperature.
3. What are the charging requirements for 48V rack-mounted lithium batteries?
For 48V (51.2V nominal) LiFePO4 batteries: (1) Float charge voltage: 53.5-54.0V (25°C); (2) Cycle charge voltage: 56.0-58.4V (25°C); (3) Max charging current: 0.5C (e.g., 50A for 100Ah battery, 250A for 500Ah battery). Temperature compensation: -8mV/°C (e.g., 52.7V float charge at 30°C). Use lithium-specific CC-CV chargers (not lead-acid chargers) to avoid overcharging (voltage >58.4V) which damages cells and triggers BMS protection shutdown.
4. How to install and expand 48V rack-mounted lithium battery systems?
Installation: (1) Fits 19-inch standard racks (2U/3U/4U models), requires minimum 600mm depth rack; (2) Plug-and-play connection via standard power connectors (no hard wiring); (3) Ensure rack ventilation (airflow ≥0.5m/s) for heat dissipation. Expansion: (1) Parallel connection up to 16 units (max 8000Ah total for 500Ah units); (2) Series connection for higher voltage (2 units for 96V, 4 units for 192V); (3) All units must be same model/batch, BMS firmware version, and initial SOC (±5%) to avoid uneven charging/discharging.
5. What communication protocols does the BMS support and how to monitor the battery?
The integrated BMS supports RS485 (Modbus RTU), CanBus, and optional TCP/IP (Modbus TCP) for remote monitoring. Key monitored parameters: cell voltage (±5mV precision), total voltage, charge/discharge current, temperature (±1°C precision), SOC (±3% precision), and fault codes (overtemp, overcurrent, low SOC). Compatible with mainstream data center/telecom monitoring systems (e.g., Huawei NetEco, APC InfraStruxure) for real-time alerts and historical data tracking.
6. What applications are 48V rack-mounted lithium batteries suitable for?
48V rack-mounted lithium batteries are optimized for space-constrained, high-reliability critical power scenarios: (1) Data center UPS systems (19-inch rack integration); (2) 4G/5G telecom base stations (outdoor/indoor cabinets); (3) Edge computing facilities (small footprint requirement); (4) Industrial UPS (cyclic load with fast recharge); (5) Renewable energy storage (solar/wind 48V systems). They are not recommended for low-voltage (12V/24V) small-scale applications (use 12V lithium batteries instead).
