Telecom Battery
Backup power for BTS, small cells and edge sites.
XGW builds its LiFePO4 batteries on Tier-1 LFP cells (CATL / BYD / EVE), managed by a smart RS485/CAN BMS with full UN38.3 documentation — the same quality system across its own Shenzhen and Zhongshan factories since 2009.

Applications
BTS & macro sites
48V LiFePO4 racks replace VRLA at cell towers, cutting weight and extending service interval.
5G small cells
Compact 48V modules power dense small-cell clusters on street furniture.
Off-grid & remote
Solar-charged LiFePO4 runs sites where grid power is unreliable or absent.
Microwave & transmission
Stable 48V backs microwave radios and optical transport with clean ride-through.
48V LiFePO4 vs VRLA vs Lead-Acid for Telecom Sites
Telecom operators weigh weight, cycle life and maintenance when moving off legacy VRLA.
| Cycle life | 3000 - 6000 cycles | 300 - 500 cycles | 200 - 300 cycles |
|---|---|---|---|
| Weight (48V 100Ah) | ~30 kg | ~55 kg | ~60 kg |
| Maintenance | None, BMS-managed | Periodic check | Frequent watering |
| Temp tolerance | -20 to 60 deg C | 0 to 40 deg C | 0 to 40 deg C |
| Total cost | Lower over life | Higher | Highest |
Choose 48V LiFePO4 for new and retrofit sites where weight, life and no-maintenance matter. Keep VRLA only where legacy racks must match.
Frequently Asked Questions
Why is telecom standardized on 48V?
48V DC is safe to touch, efficient over long runs and the historical telecom bus, so most BTS equipment expects -48V.
How long does a LiFePO4 telecom battery last?
Typical design life is 10 years with 3000+ cycles at 80% depth of discharge, far beyond VRLA in the same duty.
Does it work in cold climates?
LiFePO4 with low-temp charge protection operates to -20 deg C. Heating blankets are optional for below -20 deg C sites.
Can I monitor the battery remotely?
Yes. XGW racks ship with RS485/RS232 or SNMP BMS that reports voltage, current, temperature and state of charge to your NMS.
