Specifying a Electric Vehicle pack without the usual template paragraph

EV battery solutions. 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 We do not publish a star rating we cannot source.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: House banks, Group 24/27/31 drop-ins, small inverters

Typical size: Typical 100–400Ah; parallel for more

What actually fails

  • Starting and house loads get mixed up. A deep-cycle LiFePO4 is not a secret AGM starting battery unless we spec it that way.

How we quote it

  • Say whether this is house, start, or both. The BMS and CCA story changes.

Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

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

Electric Vehicle: the constraints that survive a find-and-replace test

EV battery solutions Alternator over-voltage will trip a cheap BMS. Ask about charge-voltage window before you bolt it in. 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. Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

Spec note

Alternator over-voltage will trip a cheap BMS. Ask about charge-voltage window before you bolt it in.

Questions we actually get

How do I size a Electric Vehicle lithium bank?

Watts × hours, then divide by voltage and by 0.8 if you want 80% depth of discharge. Add the worst ambient. That beats any calculator widget.

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.
