The 48V 50Ah telecom LiFePO4 battery — 48.0V nominal, 2.40kWh from a 15S1P pack — is the standard backup battery for telecom base stations. The critical detail: telecom 48V is 15S (48.0V, 54.75V charge), not the 16S (51.2V, 58.4V charge) used in solar storage. Mixing them up damages equipment or voids compatibility. This page explains the distinction and covers specification, cell options, and wholesale/OEM sourcing.
Specification at a Glance
| Parameter | Value |
|---|---|
| Nominal voltage | 48.0V (15S × 3.2V) |
| Rated capacity | 50Ah |
| Nominal energy | 2.40kWh (48.0V × 50Ah) |
| Cell configuration | 15S1P |
| Charge voltage | 54.75V typical (telecom standard) |
| Form factor | 19″ rack-mount (2U/3U-class) |
| Communication | CAN, RS485, SMbus (site monitoring) |
| Certifications | Per project: UN38.3, CE, IEC 62619 as required |
15S vs 16S: a Real Product-Line Distinction
Both are called “48V”, but they are different products:
| Telecom 48V (this page) | Solar 48V | |
|---|---|---|
| Series count | 15S | 16S |
| Nominal voltage | 48.0V | 51.2V |
| Charge voltage | 54.75V | 58.4V |
| Application | Telecom BTS, rectifiers, UPS | Home solar storage, hybrid inverters |
Telecom rectifiers and site power systems are engineered around the 15S charge profile. A 16S solar battery on a telecom rectifier will not charge correctly; a 15S telecom battery on a solar hybrid inverter will underperform. Always specify 15S for telecom. For solar storage, see our 51.2V 314Ah and 51.2V 280Ah pages.
Cell Options
EVE LF50K/F and REPT 50Ah-class prismatic cells are the standard telecom cell platform. The 15S1P arrangement is the industry’s established telecom structure. LJY Energy verifies cell model, grade, and batch documentation per project; UN38.3 test summaries and MSDS are supplied. Certifications are arranged per project requirements. Specifications, pricing, MOQ, and lead times are confirmed per project.
Applications
- Telecom base stations: BTS backup where grid power is unreliable, especially across Africa, Southeast Asia, the Middle East, and Latin America.
- UPS and data rooms: 19″ rack form factor fits standard cabinets.
- Hybrid site power: solar + battery + generator sites.
Buyers sourcing for African telecom markets can review our Nigeria sourcing guide for market-specific notes on telecom backup demand.
BMS and Customization Options
- Communication BMS: CAN/RS485/SMbus for site monitoring — see our BMS selection guide.
- Rack enclosure: 19″ rack-mount with front terminals and status indicators.
- Parallel operation: multiple racks in parallel for larger site autonomy.
- OEM branding: private-label racks and operator-specific specification sheets.
Wholesale and OEM/ODM
48V 50Ah 15S is a dense B2B category. LJY Energy supplies this model wholesale to telecom integrators, tower companies, and distributors. Contact us with your rectifier compatibility requirements, certification needs, and volume for a project quotation.
Certification & Compliance Notes
- UN38.3 + MSDS: mandatory for all lithium battery shipments — supplied with every order.
- IEC 62619: the key safety standard for industrial lithium batteries.
- What we never do: we do not ship with borrowed, expired, or unrelated certificates, and we do not claim certifications not yet obtained.
Shipping, Documentation & Project Terms
Lithium batteries ship as Class 9 dangerous goods with UN38.3 test summaries and MSDS. Specifications, pricing, MOQ, and lead times are confirmed per project.
Frequently Asked Questions
Can I use a 51.2V (16S) solar battery for telecom backup?
No — not directly. Telecom rectifiers expect the 15S charge profile (54.75V). Use a purpose-built 15S telecom battery.
What communication protocols are supported?
CAN, RS485, and SMbus options for site monitoring and rectifier integration. Specify your monitoring platform per project.
What certifications can you provide?
UN38.3 and MSDS are standard. CE, IEC 62619, and TÜV are arranged per project requirements — we confirm certification scope before quoting, never after.
Do you support tower-company OEM programs?
Yes. OEM/ODM includes private-label racks and matched communication firmware — request a quotation.
