Wall-Mount 48V 100Ah Lithium Iron Phosphate Telecom Tower Battery Intelligent BMS Remote Telecom Site Power

The SilkWM-TT100-48 is a wall-mount LiFePO4 battery system designed to bring intelligent, space-efficient backup power to remote and space-constrained telecom installations. With 5,120 watt-hours of energy storage in a slim 195 mm profile, it mounts directly onto shelter walls, tower equipment rooms, or street cabinet interiors, eliminating the floor space requirements of traditional rack-mounted battery banks. This makes it the ideal solution for micro base stations, distributed antenna system power nodes, and roadside telecom cabinets where every square centimeter of floor space counts.

Engineered for unattended operation in challenging environments, the SilkWM-TT100-48 features a rugged IP54-rated steel enclosure with corrosion-resistant powder coating, capable of withstanding the dust, humidity, and temperature extremes common at remote telecom sites. The integrated intelligent BMS provides industry-standard RS485 and CAN communication interfaces for seamless integration with existing network management systems, along with galvanically isolated dry contact outputs for critical alarm signaling to supervisory control and data acquisition systems. Remote site operators can monitor battery status, configure alarm thresholds, and perform diagnostic routines through standard Modbus RTU or CANopen protocols without requiring proprietary software.

• Space-Saving Wall-Mount Design: The slim 195 mm depth allows installation in narrow equipment corridors and street cabinets, with an included heavy-duty steel mounting bracket rated for 100 kg static load and seismic Zone 4 compliance.
• Industrial Communication Protocols: Native support for Modbus RTU over RS485 and CANopen over CAN 2.0B ensures plug-and-play compatibility with Huawei, ZTE, Ericsson, and Nokia network management platforms without protocol converters.
• Dry Contact Alarm Outputs: Four programmable Form-C relay outputs provide hardwired alarm signaling for critical conditions including low battery voltage, BMS fault, over-temperature, and communication loss, compatible with legacy alarm collection systems.
• IP54 Environmental Protection: The gasketed steel enclosure with breather-drain valve protects against dust ingress and splashing water, tested to IEC 60529 standards for reliable outdoor cabinet deployment.
• Intelligent Cell Balancing: Active balancing technology maintains cell voltage deviation below 30 mV throughout the entire charge-discharge cycle, maximizing usable capacity and extending pack lifespan compared to passive balancing systems.
• Hot-Swap Capable Architecture: The front-access terminal compartment and modular internal design enable rapid field replacement without disrupting parallel-connected battery strings, reducing mean time to repair to under 15 minutes.

The SilkWM-TT100-48 wall-mount battery is optimized for telecommunications infrastructure where floor space is at a premium. Key deployment scenarios include micro cell and pico cell base stations serving dense urban corridors, distributed antenna system remote power units in tunnels and stadiums, roadside fiber-to-the-home cabinet backup, railway signaling and communication power supply, and remote microwave radio repeater stations on mountain tops. The wall-mount configuration is particularly valuable in street-level telecom cabinets shared with power distribution or traffic management equipment, where the battery can be mounted above other apparatus to utilize vertical space. For network operators managing thousands of distributed sites, the standardized communication protocols enable centralized battery health monitoring through existing network operations center dashboards. The system supports both standalone operation and parallel connection of up to 8 units for scalable capacity expansion from 5 kWh to 40 kWh, providing deployment flexibility from single-sector small cells to multi-technology macro sites. In hybrid energy systems combining solar PV arrays with diesel generators, the battery serves as the primary energy buffer, absorbing excess solar generation during daylight hours and discharging during peak grid tariff periods or overnight, significantly reducing fuel consumption and generator maintenance intervals.

Silk Battery maintains rigorous quality standards throughout the manufacturing process of the SilkWM-TT100-48. Every cell batch undergoes incoming quality control including capacity grading, internal resistance matching, and high-rate discharge testing before acceptance. The assembled battery pack is subjected to a comprehensive test protocol including a 48-hour continuous cycling burn-in with BMS calibration verification, communication protocol compliance testing against reference Modbus and CANopen masters, insulation resistance testing at 500V DC between power terminals and enclosure, and a 4-hour IP54 water spray test on a statistical sampling basis. Packaging is engineered for global logistics with an inner layer of anti-static bubble wrap, custom-cut high-density polyethylene foam blocks that immobilize the battery within a double-wall corrugated carton tested to ISTA 3A drop standards, and an outer IPPC-certified fumigated wooden crate with forklift channels and tilt indicators for ocean freight shipments. Each unit ships with a complete accessory kit including wall-mount bracket, M10 anchor bolts and washers, communication cable with RJ45 and DB9 connectors, and a printed quick-start guide. Silk Battery provides a 5-year standard warranty with optional 10-year extended coverage plans, supported by a dedicated telecom technical support team available 24/7 for mission-critical deployment assistance.
