UPS Battery
48V-409V LiFePO4 battery strings for UPS systems
48V Telecom Battery 50-200Ah LiFePO4
The XGW 48V telecom battery series replaces lead-acid backup in communication base stations, 5G sites and data centers with LiFePO4 chemistry rated for 6,000+ cycles at 80% depth of discharge. A smart BMS with RS485/CAN communication reports cell-level telemetry to site managers, while active balancing, wide-temperature charging and 19-inch rack or cabinet form factors make retrofit straightforward.

Applications
5G base stations
High-cycle LiFePO4 backup for grid + solar hybrid sites. 6,000+ cycle life matches the 10-15 year service life of 5G equipment, eliminating mid-life battery replacement. RS485/CAN BMS telemetry feeds SOC and SOH to the site NMS.
Telecom cabinets
Outdoor cabinet backup with remote telemetry for unmanned sites. -20C to +60C operation and IEC 62619 safety certification suit harsh environmental conditions. Form factors designed for VRLA retrofit.
Data centers
48V rack backup for edge data centers and distributed IT rooms. LiFePO4 chemistry delivers 3-4x the cycle life of VRLA at 1/3 the volume, freeing valuable rack space. Parallel-capable for capacity expansion.
Microwave & fiber nodes
Long-duration autonomy for unattended remote sites. Smart BMS reports cell-level voltage and temperature, enabling exception-driven maintenance instead of scheduled site visits — the largest single operational saving for multi-site operators.
Solar-hybrid & off-grid sites
Wide-temperature charging supports solar-hybrid sites where grid power is intermittent. Parallel capacity expansion allows scaling backup from 50Ah to 200Ah+ as site load grows without replacing the base module.
CCTV & surveillance backup
48V LiFePO4 batteries maintain recording and transmission through grid outages at remote surveillance installations. CAN/RS485 integration with surveillance management platforms provides real-time battery health monitoring.

LiFePO4 vs VRLA vs Sodium-ion for Telecom BTS
Most base-station buyers are moving off VRLA. The real choice is between LiFePO4 and sodium-ion, with lead-acid as the legacy baseline.
| Cycle life | 6,000 cycles | 300-500 cycles | 4,000 cycles |
|---|---|---|---|
| Cold ( -20°C ) | Reduced, heater optional | Severe loss | Full discharge, no heater |
| Weight | ~1/3 of VRLA | Heaviest | ~25% heavier than LFP |
| 10-yr TCO | Lowest (few swaps) | High (3-5 swaps) | Low, more volume |
| Best for | General BTS, tropical | Legacy retrofit only | Cold / remote sites |
Pick LiFePO4 for the best weight and lifecycle at normal climates - see the 48V telecom range. Choose sodium-ion when winter temperature or heater-power draw is the constraint. Both ship from the Battery & ESS hub.
Frequently Asked Questions
How many cycles will the 48V telecom battery deliver?
Rated at 6,000+ cycles at 80% depth of discharge - typically 3-4x the service life of VRLA lead-acid, translating to lower total cost per kWh delivered.
Can the battery report status to my site management system?
Yes. The smart BMS communicates over RS485 or CAN, exposing voltage, current, SOC, SOH and cell temperatures for integration with common telecom NMS platforms.
Can I retrofit it into an existing lead-acid cabinet?
Yes. Form factors and terminal layouts are designed for VRLA replacement; our engineers provide retrofit guidance including charge-voltage settings.
What certifications come with the battery?
CE, RoHS, UN38.3 transport certification and IEC 62619 safety, with full test reports provided with each shipment.
