Rack-Mount 48V 100Ah LiFePO4 Telecom Tower Battery Backup System with Smart BMS

The ECER TTB-48100 is a high-performance rack-mount 48V 100Ah LiFePO4 battery backup system specifically engineered for telecom tower applications. Designed to deliver uninterrupted DC power to critical communication infrastructure, this solution integrates advanced lithium iron phosphate technology with intelligent battery management to ensure maximum uptime for base transceiver stations, microwave relay sites, and distributed antenna systems. With a nominal energy capacity of 4.8kWh per unit and scalable parallel configuration up to 15 units, the TTB-48100 provides flexible energy storage that adapts to diverse site power requirements. The 19-inch 3U rack-mount form factor enables seamless integration into standard telecom equipment cabinets, minimizing footprint while maximizing energy density. Every unit undergoes rigorous factory testing including capacity verification, BMS functional validation, and environmental stress screening to guarantee field reliability from day one.

• Rack-Mount Modular Architecture: Standard 19-inch 3U form factor allows stacking multiple units in telecom racks. Parallel connection supports up to 15 units for 72kWh total capacity without external combiner boxes, enabling incremental capacity expansion as site demands grow.
• Smart BMS with Remote Monitoring: Integrated battery management system provides real-time monitoring of voltage, current, temperature, and state of charge via RS485 and CAN communication protocols. Supports remote firmware updates, alarm notifications, and data logging for proactive maintenance scheduling.
• 6000+ Deep Cycle Lifespan: Grade A LiFePO4 prismatic cells deliver over 6000 cycles at 80% depth of discharge, translating to 10-plus years of service in typical telecom duty cycles. This dramatically reduces total cost of ownership compared to lead-acid alternatives requiring replacement every 2 to 3 years.
• Wide Temperature Tolerance: Operates reliably from -20°C to 60°C ambient temperature with built-in thermal management. The BMS automatically adjusts charge and discharge parameters based on cell temperature readings, ensuring safe operation even in unshielded outdoor telecom shelters.
• Deep Discharge Recovery: Advanced cell balancing and low-voltage recovery algorithms enable the battery to recover from deep discharge events without permanent capacity loss. The BMS implements staged recovery charging to safely restore cells that have dropped below nominal thresholds, a critical feature for remote sites with intermittent grid access.
• Comprehensive Safety Protection: Multi-layer protection includes over-charge, over-discharge, over-current, short circuit, and reverse polarity safeguards. Each cell is individually monitored with temperature sensors, and the flame-retardant steel enclosure meets telecom industry fire safety standards.
• Hybrid-Ready Integration: Compatible with major telecom rectifier brands including Delta, Eltek, and Vertiv. Supports hybrid operation with solar charge controllers and diesel generators, making it ideal for off-grid and bad-grid telecom sites seeking to reduce fuel consumption and carbon emissions.

The TTB-48100 is purpose-built for telecom infrastructure requiring reliable 48V DC backup power. Primary deployment scenarios include macro base transceiver stations in urban and suburban environments where space-constrained equipment rooms demand rack-mount form factors. The system excels in remote microwave relay sites powered by hybrid solar-diesel configurations, where deep cycle endurance and wide temperature tolerance are essential for year-round autonomous operation. Distributed antenna systems in tunnels, stadiums, and commercial complexes benefit from the modular scalability, allowing site engineers to match backup capacity precisely to active equipment load. The 48V nominal output aligns with standard telecom equipment voltage, enabling direct connection to rectifiers and power distribution units without intermediate voltage conversion. For tower operators managing multi-tenant sites, the RS485 and CAN communication protocols integrate with existing network monitoring systems, providing centralized visibility of battery health across the entire tower portfolio. The flame-retardant steel enclosure and comprehensive safety certifications make it suitable for co-location in shared infrastructure cabinets alongside active networking gear.

Each TTB-48100 unit is packaged in a reinforced industrial plywood case with high-density foam cushioning to prevent transit damage. The battery module is sealed in an anti-static polyethylene bag with desiccant packs to maintain optimal internal humidity. External labeling includes model number, serial number, manufacturing date, and handling instructions. Every unit ships with a QC test report documenting individual cell voltages, total capacity measurement, BMS functional verification, and insulation resistance test results. ECER provides a 5-year limited warranty covering manufacturing defects and premature capacity degradation below 70 percent of nominal within the warranty period. Technical support includes remote diagnostics via the BMS communication interface, with replacement parts available from regional service centers in Asia, Europe, and the Middle East. Custom branding, packaging, and documentation are available for OEM and ODM partnership inquiries.
