Rack-Mount 48V 150Ah LiFePO4 Telecom Tower Battery Smart BMS LCD Display Base Station Backup Power System

The SilkR-TT150-48 is a premium rack-mount LiFePO4 battery system engineered specifically for telecommunications infrastructure. With a nominal capacity of 150Ah at 48V, this battery delivers 7,680 watt-hours of reliable backup energy, ensuring uninterrupted operation of base stations, microwave relay towers, and fiber optic nodes even during extended grid outages. Its standard 19-inch 3U rack-mount form factor allows seamless integration into existing telecom equipment cabinets, making it the ideal drop-in replacement for legacy lead-acid battery banks.

Built around Grade A prismatic lithium iron phosphate cells, this telecom battery offers exceptional safety characteristics that are critical for unattended remote sites. LiFePO4 chemistry is inherently thermally stable and non-flammable, eliminating the risk of thermal runaway that plagues other lithium chemistries. The integrated multi-layer Battery Management System continuously monitors individual cell voltages, pack temperature, charge and discharge currents, providing comprehensive protection against overcharge, over-discharge, short circuit, over-temperature conditions, and cell imbalance. Every protective function is hardware-enforced with redundant safeguards, ensuring fail-safe operation in mission-critical telecom applications.

• Rack-Mount Standardization: 19-inch 3U form factor fits all standard telecom equipment racks, enabling rapid deployment and hot-swap capability for zero-downtime maintenance.
• Smart BMS with Multi-Protocol Communication: The advanced BMS supports RS485, CAN bus, and optional Bluetooth interfaces, allowing real-time remote monitoring of SOC, SOH, cell voltages, and temperature via SCADA or NMS platforms.
• Extended Cycle Life Beyond 6000 Cycles: Laboratory-tested at 80% depth of discharge, the SilkR-TT150-48 delivers over 6,000 charge-discharge cycles, equivalent to more than 15 years of daily cycling field service with proper thermal management.
• Wide Operating Temperature Range: Engineered for harsh outdoor telecom enclosures, the battery charges reliably at 0°C to 55°C and discharges from -20°C to 60°C, with an integrated self-heating film option available for sub-zero installations.
• High Energy Density Design: At only 58 kg and occupying just 3U of rack space, this unit provides 7.68 kWh of usable energy, representing a 60% weight reduction and 40% space savings compared to equivalent VRLA battery strings.
• Maintenance-Free Operation: Unlike lead-acid batteries requiring periodic water topping, terminal cleaning, and equalizing charges, the LiFePO4 rack-mount system requires zero routine maintenance over its entire service life.
• LCD Touch Screen Interface: A front-panel color touch display provides instant access to real-time operating data, alarm history, and configuration settings without requiring a laptop or external monitoring software.

The SilkR-TT150-48 rack-mount battery is purpose-built for telecommunications infrastructure where reliability is non-negotiable. Primary deployment scenarios include cellular base station backup power, microwave radio relay sites, fiber optic repeater stations, small cell network nodes, and remote telemetry equipment shelters. The battery seamlessly integrates with 48V DC power plants from major manufacturers including Delta, Eltek, Emerson, and Huawei. For regional telecom operators managing distributed networks across challenging terrain, the rack-mount form factor enables standardized hot-swap maintenance procedures that dramatically reduce mean time to repair. The system also serves as an excellent energy buffer for hybrid power sites combining solar photovoltaic arrays, diesel generators, and grid connections, smoothing load fluctuations and reducing generator run hours. In data center and colocation environments, the 19-inch rack compatibility allows this battery to function as a distributed DC backup source within server cabinets, eliminating the need for centralized battery rooms.

Every SilkR-TT150-48 battery undergoes a rigorous multi-stage quality control process before shipment. Each individual cell is capacity-tested, internal-resistance-matched, and graded to ensure consistent performance across the entire battery string. The assembled pack passes a 48-hour burn-in test with full charge-discharge cycling to validate BMS calibration, thermal stability, and communication integrity. Packaging consists of an anti-static ESD-safe inner wrap, high-density foam cushioning conforming to the rack-mount chassis, a double-wall corrugated carton rated for 200 kg stacking load, and an optional IPPC-certified fumigated wooden crate for ocean freight. Each shipment includes a comprehensive documentation package with installation manual, communication protocol guide, and factory test report. Silk Battery provides a standard 5-year warranty with optional extended coverage up to 10 years, backed by a global network of authorized service partners providing local technical support and warranty fulfillment.
