High-Capacity Telecom Backup Battery 48V 150Ah LiFePO4 Lithium Ion with Intelligent Monitoring System

The Silk High-Capacity Telecom Backup Battery delivers 48V 150Ah of premium LiFePO4 energy storage in a purpose-engineered package for critical telecommunications infrastructure. Designed as a direct upgrade path from legacy VRLA battery strings, this lithium iron phosphate system offers instantaneous backup power with zero transfer time for base transceiver stations, fiber optic repeater nodes, microwave backhaul links, and satellite communication ground terminals. The intelligent monitoring architecture provides network operators with complete visibility into battery health, state of charge, and predictive maintenance alerts through standard telecom management protocols. With an operating lifespan 5 to 8 times longer than equivalent lead-acid solutions and dramatically reduced footprint requirements, this battery system represents the next generation of telecom DC power backup. The integrated active cell balancing technology ensures uniform charge distribution across all 16 series-connected cells, preventing capacity drift and maximizing the useful energy available from each charge cycle.

• High-Capacity Energy Storage: Delivers 7.68kWh of total stored energy at 48V nominal, sufficient to power a typical macro cell site for 4-6 hours during grid outages depending on site load configuration. The high discharge efficiency above 98% ensures minimal energy loss during backup events, maximizing the usable runtime from each stored charge.
• Intelligent Multi-Protocol Monitoring: Features dual RS485 interfaces and CAN bus connectivity supporting industry-standard telecom monitoring protocols including Modbus RTU, SNMP v2c/v3, and DNP3 via external RTU gateways. Operators receive real-time telemetry data including pack voltage, individual cell voltages, charge/discharge current, state of charge, state of health, and internal temperature readings at 1-second intervals.
• Active Cell Balancing System: Unlike passive balancing systems that waste energy through resistor-based dissipation, the integrated active balancing circuit redistributes charge from higher-voltage cells to lower-voltage cells during both charging and discharging cycles. This continuous balancing maintains cell voltage deviation below 20mV, significantly extending pack cycle life and preventing premature capacity fade.
• Predictive Health Analytics: Onboard algorithms continuously track key degradation indicators including internal resistance trending, coulombic efficiency changes, and capacity fade rates. The system generates automated health reports and predictive alerts, enabling proactive maintenance scheduling and eliminating unexpected backup power failures during grid outages.
• Extreme Environment Durability: The ruggedized steel enclosure with corrosion-resistant powder coating withstands harsh outdoor telecom shelter conditions including high humidity, salt spray, dust, and temperature extremes from -20°C to 60°C. Optional integrated self-heating pads enable charging at ambient temperatures as low as -30°C for arctic and high-altitude tower deployments.
• Hot-Swappable Modular Design: The front-access terminal connections and slide-rail mounting system enable rapid replacement or capacity expansion without system shutdown. Multiple battery modules can be paralleled on a common DC bus using automatic master-slave communication, supporting seamless capacity upgrades from 7.68kWh to over 100kWh as network demand grows.
• Seamless Rectifier Integration: Fully compatible with major telecom rectifier brands including Delta, Eltek, Emerson, and Huawei. The battery accepts standard 48V bus charging profiles with adjustable float and equalize voltage settings, requiring no modifications to existing DC power plant infrastructure. Compatible with both positive-ground and negative-ground telecom architectures.

This high-capacity telecom backup battery system is purpose-built for 48V DC power backup across the full spectrum of telecommunications infrastructure. Primary deployment targets include 4G and 5G macrocell base transceiver stations where continuous uptime is critical for public safety and commercial network service level agreements. The system provides dependable backup for small cell distributed antenna systems in urban corridors, stadiums, and transportation hubs where space constraints demand compact, high-density energy storage. Fiber optic regeneration nodes and microwave relay stations benefit from the remote monitoring capability, allowing operators to verify backup readiness without costly site visits. Cable TV and broadband head-end facilities use these batteries for uninterrupted service during utility switching events. The wall-mount form factor is particularly suited for RTU and SCADA power at water treatment plants, pipeline monitoring stations, and railway signaling installations where floor space is limited. Emergency services radio repeater sites, aviation navigation beacons, and maritime coast station backup power round out the comprehensive application portfolio.

Each High-Capacity Telecom Backup Battery is manufactured under ISO 9001 certified quality management processes with full component traceability from cell procurement through final assembly. Grade A prismatic LiFePO4 cells from approved vendors undergo incoming inspection including capacity verification, DC internal resistance measurement, open circuit voltage screening, and visual defect inspection. The assembled battery system passes a rigorous production test protocol encompassing the following verification stages: 72-hour cell balancing and conditioning cycle, full charge-discharge capacity verification at 0.5C, BMS protection threshold calibration for overcharge at 3.75V per cell and under-voltage at 2.70V per cell, thermal protection verification at 65°C cutoff, communication interface loopback testing, and 2000V DC high-potential dielectric withstand testing between battery terminals and enclosure ground. Export packaging utilizes heavy-duty plywood crates with vibration-dampening neoprene isolation mounts, desiccant packs, and impact indicators. Silk Battery provides a 5-year warranty with optional annual preventive maintenance inspection programs and 24/7 technical emergency support hotline for critical infrastructure customers.
