Long float charge and backup switchover
Backup packs float-charge for long periods and must deliver reliably shortly after mains fails. The charge and discharge strategy and switchover logic are confirmed against your system interface.
Power and telecom battery packs: base stations and UPS
Telecom base stations, 5G small cells and power automation terminals stay online year round, and the backup pack must switch in reliably when mains fails. Long float charge, wide temperature and BMS communication are the three requirements.
Requirements
What this application demands of the pack
These are the electrical and mechanical points that matter in this application.
Wide operating temperature
Outdoor cabinets and base station rooms see wide temperature swings, so the operating range is confirmed against your installation environment and climate.
BMS communication
The backup system has to talk to environmental monitoring and host controllers, so the communication method and protocol are confirmed against your system interface.

What we need from you
Give us these and while meeting your performance needs we pick the most cost-effective option for you.
| Item | What to tell us |
|---|---|
| Equipment type and use | Base station backup / 5G small cell / UPS / power automation terminal (DTU / FTU / TTU) |
| System voltage and capacity | System voltage such as 48 V / 51.2 V and the backup duration required |
| Installation environment | Indoor or outdoor cabinet, and the temperature range |
| Communication method | Communication method and protocol with the host or environmental monitoring |
| Target market | Destination country, used to confirm certification and transport document items |
| Capacity & discharge | Built from 0.1 Ah to 600 Ah to your requirement — common levels such as 10 Ah, 20 Ah, 50 Ah, 100 Ah and 200 Ah are all confirmed per model; continuous and peak rates are matched to the duty cycle |
The above describes the general matching logic only. The final selection is made by us — your requirements come first, and we work to reduce your cost as far as safety allows.
FAQ
Questions about power and telecom packs
Which chemistry is used for power and telecom packs?
Backup is usually assessed from the LFP direction, which suits long float charge and backup switchover in terms of cycle performance and thermal stability. The final choice is ours to make based on your system requirement — lithium-ion, sodium-ion or solid-state, we match the more suitable option.
Can the pack be built to our system voltage?
Yes. Series/parallel layout and mechanical design follow your system voltage, capacity and backup duration. The form factor is prismatic, built to your cabinet and interface requirements.
Will the BMS work with our environmental monitoring?
Tell us your host controller or monitoring model and the required communication method and protocol parameters. We confirm the BMS configuration against that, so nothing fails to connect after installation.
Which transport compliance documents are needed for export?
This is confirmed per target market and per model. For lithium-ion packs we can provide the UN38.3 test report and summary, air and sea transport identification reports, MSDS and the 1.2 m drop test report, with the applicable items confirmed against your order requirements and target market.
