Ask five LiFePO4 OEM/ODM suppliers for “a custom pack” and you will get five quotes that cannot be compared. One assumes a different cell brand, another a different BMS continuous rating, another a different certificate scope. An OEM RFQ works when every supplier answers the same field map in writing.
General procurement guidance as of 31 October 2026. Not legal, certification or engineering advice. Market rules and certificates depend on product, channel and destination country.
Short answer
- Start with five lines: application and duty cycle, nominal voltage, capacity/energy (Ah and kWh), target markets, and annual volume band.
- Mark every other line Required / Preferred / Open (advise me). A supplier that flags what it cannot confirm is more useful than one that leaves blanks.
- Use the full A–M checklist on our OEM/ODM page (or the printable PDF) before samples.
- Keep supplier vetting separate from custom-spec RFQ: see how to verify a China LiFePO4 supplier.
Who this checklist is for
Wholesale importers, brand owners, equipment OEMs, ESS integrators, distributors and installers who need a private-label or project-confirmed LiFePO4 pack — not a one-line “send quote” email. If you only need a catalogue model, start from the product catalog or a standard page such as the 51.2V 200Ah (10.24kWh).
Five fields that unlock a first reply
| Field | What to write | Why it matters |
|---|---|---|
| Application & duty cycle | Golf cart, RV house bank, marine, telecom, home ESS, AGV; cycles/day | Sets cell choice, BMS settings and warranty basis |
| Nominal voltage | 12.8 / 25.6 / 51.2 V (48V class) or other | Must match equipment and charger voltage window |
| Capacity / energy | Ah and Wh/kWh | Ah alone hides voltage; usable energy depends on DoD |
| Target markets | Every country of sale | Drives certificates, labelling and languages |
| Annual volume band | Band is enough (e.g. pilot then yearly range) | Lets the supplier plan cells and quote tiers |

LJY Energy is a China-based LiFePO4 battery supplier and OEM/ODM solutions provider. Certificates are available or arranged per project; testing and certification fees are borne by the buyer. MOQ, price, lead time and warranty length are confirmed in the quotation — not as public list claims on this page.
Common RFQ mistakes that force a re-quote
- “Grade A cells” with no brand/model — write measurable criteria or a named cell model (see Grade A vs Grade B).
- Brand-level inverter “compatible with X” — closed-loop needs exact model + firmware + protocol, confirmed per project.
- Ah without Wh/kWh or voltage — two “100Ah” packs at different voltages are not comparable.
- Mixing supplier vetting with custom-spec — use the verify guide for who produces and which documents; use A–M for the pack you want built.
