Grid interruption
Keep network equipment online through outages, unstable utility power, or generator transfer.
Remote network uptime in extreme cold
Battery Backup for Outdoor Telecom Equipment
Custom low-temperature LiFePO4 backup power for outdoor telecom cabinets, broadband access points, 5G small cells, PoE switches, and unattended infrastructure.
Unattended sites cannot wait for warm-up
-40°C cabinet exposure
Avoid a heater warm-up delay when the site needs immediate discharge and winter charging.
Remote maintenance
Reduce cold-related battery replacements and emergency visits to hard-to-reach sites.
Outdoor equipment scenarios
Outdoor telecom cabinet
DC backup for radios, switches, controllers, cooling, and cabinet monitoring.
Broadband access point
Runtime for remote fiber, fixed-wireless, and last-mile access equipment.
5G small cell
Cold-weather battery support for compact base stations and edge network equipment.
Outdoor PoE switch
Backup for PoE switches and the connected cameras, access points, or sensors.
Surveillance box
One battery system for cameras, routers, recorders, and communication modules.
Low-temperature LiFePO4
Use the winter charging window for charging
Wiltson packs retain at least 90% discharge capacity and support up to 3C discharge at -40°C. At -30°C they charge directly in 2 hours, while a heated pack needs about 5 hours of warm-up plus 2 hours of charging.
See the broader outdoor battery backup power supply guide for 12V, 120V, UPS, enclosure, and OEM options.

Parameters for sizing telecom backup power
| Parameter | Project input |
|---|---|
| Load profile | Continuous watts, startup current, peak current, and duty cycle |
| System voltage | 12V, 24V, 48V, or a project-specific DC bus |
| Required autonomy | Backup hours or days after grid or solar input is lost |
| Temperature | Minimum charging and discharging temperature at the enclosure |
| Charging source | Grid charger, rectifier, solar controller, or hybrid input |
| Mechanical limits | Cabinet space, mounting, connectors, cable routing, and target IP rating |
| Communications | Optional CAN, RS485, UART, Bluetooth, alarms, or dry contacts |
Frequently asked questions
I need outdoor battery backup for broadband access point installation. What information do you need?
Send the access-point and network-equipment voltage, normal and peak power, required backup time, minimum site temperature, charging source, available enclosure space, connector requirements, and expected quantity.
What are the best battery backup solutions for outdoor 5G equipment?
The best solution matches the DC bus, peak radio load, autonomy target, charging source, cabinet environment, remote monitoring, and service strategy. Low-temperature LiFePO4 is useful where standard batteries cannot charge reliably or deliver startup current in winter.
Can the battery fit inside an existing outdoor enclosure?
Yes. Wiltson can customize pack dimensions, mounting, cable direction, connectors, BMS, and communications around the available cabinet space. Thermal and ingress-protection requirements must be checked at system level.
Can one backup system power a PoE switch and surveillance equipment?
Yes, when the battery and power conversion are sized for the combined continuous load, PoE budget, startup peaks, required runtime, and system voltage.
