48V Lithium Telecom Batteries
48V server rack packs at 50Ah, 100Ah and 200Ah for base stations, exchanges and data centres, 6000+ cycles, 19-inch format.
Telecom And Data Centre Backup
48V rack packs at 50Ah, 100Ah and 200Ah for base stations, exchanges and DC plant, 6000+ cycles, parallel to fifteen units.
Telecom backup is judged on two things: whether the site stays up, and how often somebody has to drive to it. The 48V range is built around both - 19-inch modules that fit the cabinets already in the network, a smart BMS that reports cell state continuously, and a 6000+ cycle rating so the replacement interval is measured in a decade rather than in seasons.
Sector pain points
What Goes Wrong In This Sector
VRLA Fails Quietly
A lead-acid string loses capacity without warning and is discovered at the moment the grid drops. A lithium BMS reports state of charge and balance continuously.
Truck Rolls Cost More Than Batteries
For a remote tower or a rural exchange, the drive is the expensive part. Cycle life and monitoring are what cut the visit count.
Cabinet Space And Weight
482x480x132 mm modules at 27 kg for 2.4 kWh and 40 kg for 4.8 kWh, against a VRLA string that needs two people and a trolley.
Charge Profile Mismatch
A rectifier set for lead-acid will not charge a lithium pack correctly. It is a settings change, but it has to be planned rather than discovered.
What buyers need
What This Sector Actually Asks For
- 19-inch modules that fit the existing cabinet
- Hold-up time calculated from the real site load
- Continuous state-of-charge reporting over RS485 or CAN
- Parallel expansion as the site load grows
- Cold-climate charging protection where the cabinet is unheated
- UN38.3 and MSDS documentation for shipping to site

Where Most Buyers In This Sector Start
How we work with you
From Enquiry To Repeat Supply
Send The Site Load And Hold-Up Target
Load in kW and the hours you need. That gives the kWh and therefore the module count.
Confirm The Cabinet
Rack depth, available U height and whether the enclosure is indoor or outdoor.
Check The Rectifier
Charge profile and communication - RS485 or CAN - so commissioning is a settings task rather than a surprise.
Pilot Site First
Most operators run one site before a rollout. Sample units are available for that.
Rollout With Documentation
Each shipment travels with UN38.3, MSDS and the certificate set for the model.

FAQ
Telecom And Data Centre Backup Questions
How many modules can I parallel?
The published telecom range parallels up to fifteen units. Send the hold-up requirement and we will confirm the count and the arrangement for your model.
Will these work with my existing rectifier?
Usually, after a charge profile change to LiFePO4 and a communication setup over RS485 or CAN. Send the rectifier brand and model and we will confirm before you order.
Can I keep the old lead-acid string as extra capacity?
No. Mixing chemistries on one bus means the lithium pack carries the load while the lead-acid string sits on float and ages out. Replace the string.
What is the IP rating on the telecom modules?
IP20 on the 50Ah and 100Ah rack modules - an indoor cabinet rating. For outdoor sites the enclosure provides the protection; tell us what the cabinet is and we will confirm.
What about sites that freeze?
Specify the optional heating on the 48V 100Ah pack. Charging LiFePO4 below 0 degrees Celsius without heating permanently loses capacity, and an unheated cabinet in a cold climate will do exactly that.
Can you build these under our own brand?
Yes. OEM and ODM are standard here: case, label, protocol list and packaging to your specification, with a sample for approval before the bulk order.
