What Is the SG48100P 48V 100Ah Server Rack LiFePO4 Battery?
The SG48100P is a 48V 100Ah lithium iron phosphate (LiFePO4) battery designed for server racks, renewable energy systems, and industrial applications. It offers high energy density, long cycle life (3,500+ cycles), and advanced safety features like overcharge protection. Ideal for UPS backups, solar storage, and telecom infrastructure, it ensures reliable, scalable power with minimal maintenance.
What Safety Features Are Integrated Into the SG48100P?
The SG48100P includes multi-layer protection: BMS-controlled overcharge/over-discharge prevention, short-circuit shutdown, and thermal runaway mitigation. Its flame-retardant casing and cell-level fuses ensure stability during extreme loads. UL1973 and UN38.3 certifications validate its compliance with industrial safety standards.
Advanced thermal management uses nickel-plated copper busbars to maintain cell temperatures within ±2°C variance during 1C discharge. The battery’s self-diagnostic system performs 72-point checks every 15 minutes, detecting anomalies like internal resistance spikes or electrolyte leakage. In critical scenarios, the multi-stage disconnect mechanism isolates faulty cells within 50 milliseconds while maintaining 80% of rated capacity through redundant circuits. These features make it compliant with NFPA 855 fire codes for energy storage systems in occupied spaces.
How to Install and Configure the SG48100P in a Rack System?
Mount the 19-inch rack-compatible unit using M6 bolts, ensuring 4-inch side clearance for airflow. Connect terminals with 35mm² copper cables (torque to 2.5 N·m). Use dip switches to set battery addresses in parallel setups. Calibrate voltage thresholds via the LCD interface or proprietary software to match inverter specifications.
For large-scale deployments, implement a star topology when connecting more than 8 units to minimize voltage drop. The battery supports CAN 2.0B and RS485 protocols for integration with third-party monitoring systems. Grounding resistance must be below 0.1Ω using 10AWG wires to prevent EMI interference. During commissioning, perform a full capacity test by discharging to 44V (2.75V/cell) under 50A load, then recharge to 58.4V while verifying balancing currents stay under 2A.

FAQ
- Does the SG48100P support parallel connections?
- Yes, up to 16 units can be paralleled (1600Ah total) using built-in current-sharing technology. Ensure all batteries are within 0.5V voltage difference before connecting.
- What warranty coverage applies?
- Redway provides a 7-year warranty, covering capacity below 80% or BMS failures. Exclusions include water immersion, physical damage, or use below -25°C.
- Is external cooling required?
- Not under normal loads. The SG48100P’s aluminum heatsink dissipates heat at 120W/m·K. Add forced airflow only if ambient temperatures exceed 45°C or during sustained >0.5C charging.
