Custom Battery Packs for Telecom Backup Power
A telecom backup battery keeps base stations, switches and cabinet equipment running during an outage. Jetray builds custom 48 V LiFePO4 packs for telecom equipment makers and integrators, in rack and cabinet formats.

Why operators move from lead-acid to lithium
Lithium costs more up front. Whether it pays back depends on site visits and the grid.
- 01Less weight and space in shelters and cabinets.
- 02No watering and fewer site visits.
- 03Many cycles where the grid is unstable.
- 04Remote monitoring of state of charge and faults.
What a backup pack must handle
Formats
For tower-side equipment, see signal tower packs →.
- 01Rack-mount standard 19-inch rack modules; send the rack depth and height.
- 02Cabinet module sized to your cabinet shelf.
- 03Wall-mount for small sites.
- 0412 V and 24 V packs: for gateway, CCTV and IoT equipment.
How to size
Send these. We propose the cells and layout, and supply a matching charger. Cell selection → Charger and communication →
- 01Load in watts and its peak.
- 02Backup time during an outage.
- 03DC bus voltage and charger.

Documents, order size and delivery
UN38.3, IEC 62133 and MSDS documents are available, with transport and certification reports for the shipment.
Other requirements, such as operator approval, depend on your customer. Energy storage products can be ordered in small quantities, even a few units. Custom packs usually take one to two months. Quality and certification →
