XGW Digital Technology is a China-based commercial and industrial energy storage system (C&I ESS) manufacturer and lithium battery OEM/ODM, serving operators, factories, solar EPCs and data centers since 2009. Our two pillars: telecom & UPS lithium batteries (48V LiFePO4 rack, UPS replacement, sodium-ion) and C&I ESS — rack and containerized LiFePO4 with PCS/BMS for peak shaving, self-consumption and backup. ESS is our 2027–2030 flagship. UN38.3 / IEC / CE certified, OEM/ODM from 500 units.

Telecom & UPS Battery Product Lines

Commercial & Industrial ESS — Our 2027–2030 Focus

Energy storage is moving from backup to a primary site asset. XGW's C&I ESS line pairs LiFePO4 racks or containers with a PCS inverter and EMS for peak shaving, solar self-consumption and backup. We size capacity and power to your tariff and load, then certify and ship as one package.

Comparison: LiFePO4 vs VRLA for Telecom & UPS

Why LiFePO4 Replaces VRLA

LiFePO4 telecom/UPS batteries are typically 50% lighter, last 3-5x longer (2000-6000 cycles), need no watering or equalization, and recharge faster — lowering total cost of ownership despite a higher upfront price. VRLA is cheaper initially but fails sooner in float/cyclic duty.

Telecom Battery vs ESS Battery

Telecom batteries are 48V backup packs built for high discharge to BTS/UPS. ESS batteries are larger rack/cabinet systems (100kWh+) for peak shaving and solar. XGW makes both as separate product families.

Frequently Asked Questions

What is a 48V telecom lithium battery?

A 48V telecom lithium battery is a rack or cabinet LiFePO4 pack that replaces lead-acid as backup for base stations, 5G small cells and off-grid nodes. XGW builds 48V (50-200Ah+) strings with BMS, CAN/RS485 communication and -20C to 60C operation. See our 48V telecom battery.

Who manufactures 48V telecom batteries in China?

XGW Digital Technology is a China-based telecom & UPS lithium battery manufacturer and supplier, producing 48V LiFePO4 rack batteries, BTS backup packs and UPS replacement strings, OEM/ODM for 50+ countries since 2009. We hold UN38.3, IEC, CE and ship global.

What lithium battery is used for telecom towers?

LiFePO4 (lithium iron phosphate) is the standard for telecom towers and BTS sites: stable chemistry, long cycle life (2000-6000 cycles), wide temperature range and no maintenance. XGW also offers a sodium-ion option for -40C cold sites.

Can LiFePO4 replace VRLA in a UPS?

Yes. XGW UPS lithium batteries drop into standard 48V-409V UPS architectures, replacing VRLA strings with longer-life LiFePO4, faster recharge and lighter weight. See our UPS lithium battery range.

What is UPS lithium battery replacement?

UPS lithium battery replacement swaps lead-acid strings in UPS rooms and data centers for LiFePO4 packs — typically 50% lighter, 3-5x the cycle life, no watering, and a lower total cost of ownership over the system life.

What certifications do telecom lithium batteries need?

For export: UN38.3 (transport), IEC 62619 / UL 1973 (cell & pack safety), IEC 61000 (EMC) and CE. XGW designs to these and can support customer-specific marks.

How long do telecom LiFePO4 batteries last?

Typical telecom LiFePO4 packs deliver 2000-6000 cycles at 80% depth of discharge, equating to 5-10 years of float/cyclic backup duty depending on temperature and discharge rate.

Do your batteries support BMS communication?

Yes. Every XGW telecom and UPS pack includes a BMS with RS485/CAN (and optional SNMP) reporting voltage, current, temperature and state-of-charge for remote NOC monitoring.

Can you OEM/ODM telecom and UPS batteries?

Yes. XGW supports OEM/ODM from a 500-unit MOQ — custom voltage, capacity, enclosure, connectors and communication protocol — with samples in 3-7 days and certified production.

What is the difference between a telecom battery and an ESS battery?

Telecom batteries are optimized for 48V backup (high discharge, BTS/UPS). ESS batteries are larger rack/cabinet systems (100kWh+) for peak shaving and solar storage. XGW makes both; see our C&I ESS center.

What is a commercial and industrial energy storage system (C&I ESS)?

A C&I ESS is a rack or cabinet LiFePO4 battery system (typically 30kWh to several MWh) paired with a PCS inverter that stores energy from the grid or solar and discharges it for peak shaving, demand-charge reduction, backup and self-consumption. XGW builds rack and containerized C&I ESS as OEM/ODM.

Who manufactures C&I energy storage systems in China?

XGW Digital Technology is a China-based commercial and industrial energy storage system (C&I ESS) manufacturer and lithium battery OEM/ODM, producing rack and containerized LiFePO4 ESS with PCS and BMS, UN38.3 / IEC / CE certified, serving 50+ countries since 2009.

How does battery storage reduce electricity cost for a factory?

By charging during off-peak tariffs and discharging during peak windows (peak shaving) and by clipping demand-charge spikes, a C&I ESS cuts a factory's demand charges and energy spend without changing production. Solar self-consumption adds further savings by storing PV for later use.
