Laboratory LiFePO4: size the load, then the voltage

People land on a Laboratory page because the last bank died early or would not charge. Laboratory equipment backup. 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 We do not publish a star rating we cannot source.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: Trolling motors, mid-size solar, light commercial

Typical size: Typical 100–400Ah

What actually fails

  • Runtime and a charger that will not cook a cell in a closet. Consumer jump-pack marketing does not belong here.

How we quote it

  • We need device voltage, duty cycle, and whether the pack is inside the device envelope.

24V on this URL

Halves current versus 12V for the same watts. Confirm the motor or inverter is actually 24V before you order.

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

What to spec for Laboratory

Laboratory equipment backup If the device is FDA-adjacent, say so up front. Documentation is the long pole. 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. Halves current versus 12V for the same watts. Confirm the motor or inverter is actually 24V before you order.

Spec note

If the device is FDA-adjacent, say so up front. Documentation is the long pole.

Questions we actually get

How do I size a Laboratory 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.
