Why a Complete RFQ Gets a Better Quote
A quotation is only as accurate as the information behind it. When a request for quotation arrives with a one-line product name and a quantity, a supplier must guess the application, the duty cycle, the environment and the certification needs, and every guess adds a margin of safety to the price. When the request is complete, the supplier can select the right model from the catalog, quote closer to the real cost, and answer with fewer round trips. For the buyer, preparing a disciplined RFQ is the cheapest way to shorten a sourcing cycle and to make several quotations comparable line by line.
Describe the Application First
Start with what the battery must do. State the end product or project type, the daily energy throughput, the load profile with running and peak currents, and how often the system cycles. A pack for a solar shop that cycles daily in a hot climate is a different sourcing problem from a backup pack that waits months between events, even at identical Ah. Suppliers pick models, charge limits and BMS settings from the application, so the application paragraph is the most valuable text in the request.
Electrical Requirements
- Nominal voltage class: 12.8V, 25.6V or 51.2V to match the inverter or load
- Capacity in Ah or energy in kWh, with the usable share the project needs
- Continuous discharge current and the peak current with its duration
- Charge source and the maximum charge current available
- Communication needs: CAN, RS485 or Bluetooth, and the protocol expected at the far end
- Series and parallel grouping intended for the project
Mechanical and Environmental Requirements
Physical constraints decide feasibility as often as electrical ones. State any maximum dimensions and weight, the mounting method, the expected IP rating if the unit sits outdoors or in a dusty space, the operating temperature range at the site, and altitude if relevant. For products that travel on to end users, note transport orientation and any drop or vibration expectations. Where a catalog model does not fit, this section is what lets a supplier judge whether an OEM variation is realistic and what it would cost to evaluate.
Market and Certification Requirements
Name the destination market and the documents that market requires. For LiFePO4 storage products, CE marking and the UN 38.3 transport documents are the baseline that most export orders reference; other standards may apply depending on the market and the installation type, and whether additional certificates exist for a given model is a fact every buyer should confirm in writing rather than assume. State in the RFQ which documents the project must have, so the quotation includes them or honestly marks them as pending, instead of discovering the gap after the order.
Commercial Items
- Quantity: the trial order, the first production order and the annual projection, stated separately
- Trade term and port: EXW, FOB or CIF, with the named port for FOB and CIF pricing
- MOQ and lead time, which are order-specific facts to be confirmed in writing against the order
- Payment terms expected for a first order and for repeat orders
- Packaging: export carton standard, palletization, and any retail or branded packaging requirement
- Labeling and OEM scope: logo placement, artwork files, manual language, and who approves proofs
- Target unit price and the currency, so the supplier can respond honestly rather than not at all
The RFQ Checklist
| Section | Include | Why the supplier needs it |
|---|---|---|
| Application | End use, daily cycling, load profile, climate | Model selection and charge settings |
| Electrical | Voltage class, Ah, currents, communication | Correct BMS and inverter match |
| Mechanical | Size, weight, mounting, IP, temperature | Feasibility check against the catalog |
| Certification | Destination market and required documents | Document scope inside the quotation |
| Commercial | Quantities, trade term, packaging, OEM scope | Complete price with no hidden assumptions |
| Timeline | Project dates and quote validity needs | Realistic scheduling of samples and production |
Samples and Validation
State in the RFQ whether a sample precedes production, how many units, and what the sample must prove: a capacity check, a communication test with the project's inverter, or a field trial period. Sample policy, sample cost and whether that cost is credited against the production order are commercial terms to be confirmed in writing with the quotation. A buyer who signals a serious validation plan receives a different quality of attention from a supplier's engineering team than a buyer who asks only for a price.
What a Good Quotation Contains in Return
Judge the response with the same discipline. A complete quotation states the exact model and its datasheet revision, the unit price at the stated quantities, the trade term and port, the validity period, the packing specification, the documents included, and any open points listed as pending rather than quietly omitted. A quotation that answers every line of the RFQ is itself evidence of how the supplier will behave during production and after delivery.
Where YueQi Fits
YueQi New Energy quotes across a catalog that covers 12.8V and 25.6V battery packs, 51.2V mobile storage batteries, home energy storage units at 4.2kW with 8kWh and 6.2kW with 16kWh, and portable power stations from 400W to 2500W. An RFQ prepared along the lines above can be matched to catalog models directly, and OEM variations are evaluated from the same information. Quotation terms, MOQ and lead time for each order are to be confirmed in writing.
Summary
A strong RFQ reads like a specification: application, electrical numbers, mechanical limits, certification needs and the commercial frame. It costs an hour to prepare and saves weeks of quotations that cannot be compared. Send the same checklist to every supplier and the responses will line up line by line, which is exactly where a sourcing decision becomes easy.
Next step
Send your application, target specification and estimated quantity with your inquiry, and we will confirm matching products, samples and document requirements in writing. See the product lines or request a quote.
