48V LiFePO4 lithium batteries for telecom
This is the second product line and it behaves nothing like the rectifier business. Here the buyer usually has a healthy plant and a dying VRLA string, and the decision is a sizing exercise: how much real autonomy the site needs, and whether the existing rectifier shelf can charge lithium correctly.
Availability & lifecycle
Active, competitive and well supplied. The differentiator is not sourcing, it is sizing the bank correctly and confirming the charging profile before anyone ships anything.
Models we are asked for
| Part number | Model | Indicative specification |
|---|---|---|
| — | 48V LiFePO4 50Ah | 19" rack · integrated BMS · RS485/CAN |
| — | 48V LiFePO4 100Ah | 19" rack 3U · integrated BMS · RS485/CAN |
| — | 48V LiFePO4 150Ah / 200Ah | 19" rack 4U · integrated BMS · parallel capable |
Specifications are indicative and published by the manufacturer. Availability, exact revision and lead time are confirmed in the written quotation.
Where it is used
- VRLA replacement in existing 48V plants
- Cellular tower and repeater backup
- Fiber node and ISP cabinet autonomy
- Sites with weight, footprint or temperature constraints
What to send us
The site load in amps or kW, the autonomy you actually need in hours, the rectifier or plant model that will charge the bank, and the ambient temperature range. Those four things determine the answer; the part number does not.
Compatibility notes
Lithium is not always the right call. If a site is cool, rarely cycles and has space, a like-for-like VRLA replacement can be the cheaper answer over the asset life — and we will tell you when that is the case.
Certification & transport
Transport and safety documentation matters on every lithium shipment: UN38.3 for transport, IEC 62619 for industrial cells, plus MSDS. We confirm which certificates come with a given product before you order.
Common questions about this family
Can my existing rectifier charge a LiFePO4 bank correctly?
That is the question to answer before buying anything. Lithium needs a charging profile and voltage window that not every legacy 48V plant can deliver, and the controller has to be able to talk to the BMS or at least not fight it. Send the rectifier or plant model along with the load and we will tell you whether it works as-is.
How much autonomy do I actually need?
It is set by four things: the site load in amps or kW, the hours of autonomy the site genuinely requires, the charging capability of the plant, and the ambient temperature range. Send those four and you get a useful answer; send the part number of your old VRLA and you get a guess.
