Telecom Base Station Backup Power Solution
Diesel backup at telecom sites carries a persistent cost structure: fuel delivery, theft, engine maintenance and generator replacement cycles that rarely match the network’s economic life. LiFePO4 backup banks remove most of that,…
Telecom Base Station Backup Power Solution
What a telecom site looks like
A base station is a small power system that must survive the grid, not depend on it. Sites are spread over large areas, most have no air conditioning, and field teams reach them on a planned route.
- Macro sites with 1-3 kW average load, indoors or in outdoor cabinets
- Micro and pole-mounted sites with smaller loads and very little room
- Outages measured in hours and, in weak-grid areas, in days
- Rectifiers and site controllers from several generations, with mixed communication interfaces
What the design has to respect
- Autonomy set by the longest credible outage, not by the average one
- Alarms that reach the network management system, because nobody is standing at the site when a bank fails
- Charge current limits that protect older rectifiers and avoid tripping site breakers
- An operating window that matches the cabinet’s real temperature, not a laboratory one
- Retrofit form factors that fit existing 19-inch racks, cabinets and poles
Replacing Diesel Without Losing Autonomy
The engineering question at a telecom site is not whether lithium can deliver backup power. It is how many hours of autonomy the network requires at each site class, and what that implies for bank sizing and cooling.
- Macro sites with 1-3 kW average load typically use 10-30 kWh banks for 8-12 hours of autonomy
- Micro and pole-mounted sites use 5-10 kWh compact banks for 4-8 hours
- Outage profiles are used to size for the longest credible event rather than the average
- Where outages exceed storage autonomy, solar or a small genset is retained as a second layer
- Discharge depth limits are configured per site to balance autonomy against cycle life
We support both full diesel removal at sites with reliable daily recharge, and hybrid configurations where the genset runs only during extended outages.
Remote Monitoring and Fault Handling
Telecom operators manage thousands of sites with limited field teams, so the backup battery must be a monitored asset, not a black box behind a door.
- BMS communication over RS485, CAN or SNMP toward the site controller or network management system
- Alarm set covering low voltage, cell imbalance, over-temperature, communication loss and fuse or contactor failure
- State-of-health reporting so underperforming sites are identified before an outage exposes them
- Charge current limiting to protect weak rectifiers and avoid tripping site breakers
- Discharge event logging with depth and duration, supporting outage reporting and SLA analysis
Protocol mapping is agreed during the quotation stage; we can supply register maps and test the interface against your controller before shipment. Where a site controller is not available, the BMS can be configured to log locally and push periodic summaries when connectivity returns, so outage data is not lost.
Site Conditions, Installation and Lifespan
Telecom cabinets are often the hottest place on a site, and battery life is governed by temperature as much as by cycling.
- Rack, cabinet and wall-mount form factors for indoor, outdoor and pole installations
- IP55 to IP65 enclosures with filtered ventilation for dusty environments
- Operating window of -20C to +60C, with charge derating above 45C
- Front-terminal access and standard 19-inch rack compatibility for retrofit into existing cabinets
- Weight and footprint specified per model so structural and civil requirements can be checked in advance
Expected service life of eight to twelve years at moderate temperatures reduces replacement cycles relative to lead-acid, and the higher usable depth of discharge means a smaller lithium bank can replace a larger lead-acid one. Packs ship with terminals protected and state of charge held at a level appropriate for transport, and commissioning includes a full charge cycle to confirm delivered capacity before handover.
What this design gives you
Fuel and Logistics Cost Removal
Eliminating routine diesel consumption removes fuel purchase, transport, storage and theft losses, which typically dominate the operating budget of an off-grid or unreliable-grid telecom site over its lifetime.
Fewer Generator Interventions
Without continuous genset running, engine servicing, filter replacement and generator overhaul cycles are reduced to emergency-only events, cutting maintenance labour, parts consumption and unplanned site visits.
Temperature-Aware Protection
BMS charge and discharge derating above defined temperature thresholds protects cells in hot cabinet environments and preserves long-term capacity in locations where active cooling is impractical or unavailable.
Network Management Integration
Standard protocols and supplied register maps allow battery status and alarms to appear in the operator’s existing network management system, so field teams receive faults through established operational workflows.
Higher Usable Capacity
Deeper usable discharge means a smaller and lighter lithium bank replaces a larger lead-acid installation at comparable autonomy, reducing structural loading on poles, rooftops and cabinet floors.
Long Service Life
LiFePO4 chemistry supports eight to twelve years of typical service at moderate temperatures, lowering total cost per site-year and reducing the frequency of truck rolls for battery replacement.

How an order runs
These are the terms we quote on for backup banks and their interface hardware. Voltage, capacity, quantity and destination are fixed on the quotation, and every figure below is confirmed in writing before production starts.
| Minimum order | 20 units per model for a production order. Single units are available as paid evaluation samples, credited against your first production order. |
| Lead time | 25 days after the deposit is received for a standard batch. Tooling, custom BMS or project-specific capacity is scheduled separately and confirmed on the quotation. |
| Payment | T/T: 30% deposit with the order, balance against the bill of lading copy. |
| Shipment | Tell us the destination port or door. The quotation states the Incoterm and the freight option we are quoting, so the delivered cost is comparable across suppliers. |
| Packing | Packed to the packing instruction applying to UN3480 or UN3481, terminals protected, lithium battery mark and hazard label applied, pallets strapped and shrink-wrapped. |
| Documents with the goods | Packing list, commercial invoice, MSDS, UN38.3 test summary and report, shipper’s declaration for dangerous goods, and the bill of lading or air waybill. |
| Per unit | Datasheet for your model and the end-of-line test record for that serial number. |
| Warranty | 3–5 years, depending on model, written into the contract. |
| HS classification | Lithium-ion accumulators, heading 8507.60. The national tariff line and duty rate are confirmed against your destination before the order is placed. |

How to verify before you commit
The bank and the interface are proven together before rollout.
- Bank sizing signed off against your own outage profile, with the assumptions written down
- A register map and protocol test against your site controller or NMS, done before shipment where you supply a test target
- UN38.3 test summary and report, plus the transport documents for the delivered configuration
- Datasheet, end-of-line test record and BMS parameter list per model
- A pilot site plan, so the first installation is used to confirm alarm mapping and autonomy
