Telecom lithium banks — duty cycle before brochure cycle life

People land on a Telecom page because the last bank died early or would not charge. Reliable power for telecommunications infrastructure. We start from load, charger, and temperature — then cells.

CAGE 93CZ2

UN38.3 transport docs on request. DUNS 109774429. We do not publish a star rating we cannot source.

This rail: Residential solar, telecom, warehouse trucks

Typical size: Typical 100–600Ah; parallel for autonomy

What actually fails

  • OEM and government quotes stall on paperwork (CAGE, UN38.3, traceability), not on a missing adjective.

How we quote it

  • Lead with CAGE 93CZ2, UN38.3, and the actual voltage the platform already uses.

Default house and telecom rail once you are past a few kilowatts. Inverter protocol has to match.

If you delete the voltage, the Telecom constraints above should still make sense. That is the point.

What to spec for Telecom

Reliable power for telecommunications infrastructure Send the interface drawing before the cell count. Form factor kills more programs than chemistry. Voltage overlay on this URL is only there because the equipment rail is real — delete the voltage and the duty-cycle advice should still read as a sentence. Default house and telecom rail once you are past a few kilowatts. Inverter protocol has to match.

Spec note

Questions we actually get

How do I size a Telecom lithium bank?

Start from the load you cannot lose. Everything else is optional capacity. We will convert that into Ah at the voltage you already have.

Can I keep my existing charger?

If it can hold a lithium charge curve (higher absorb, little or no float), maybe. Send the charger model. A lead-acid-only charger is how people cook packs.

What paperwork can you send?

UN38.3 is the usual transport packet. CAGE 93CZ2 and DUNS 109774429 for government bids. Other marks depend on the SKU — we send PDFs we actually have.
