Railway LiFePO4: size the load, then the voltage

Railway signal batteries. The useful question is hours and ambient, not a synonym for lithium. ChargeX builds LiFePO4 packs (CAGE 93CZ2, UN38.3) and will quote the voltage your equipment already uses.

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 We do not publish a star rating we cannot source.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

  • Duty cycle and recharge window. If the vehicle cannot opportunity-charge, lithium’s ROI story changes.

How we quote it

  • Hours per shift, charger location, and tray size. Then chemistry.

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

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

Railway: the constraints that survive a find-and-replace test

Railway signal batteries We do not guess CCA for a traction pack. Say traction or start. 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.

Questions we actually get

How do I size a Railway 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.
