xygbattery.com (hereinafter referred to as “this Website”) is operated by Dongguan Junda New Energy Technology Co., Ltd. (hereinafter referred to as “we”). This page explains how a custom battery order moves from your first message to a delivered shipment, what we need from you at each step, and how long each step normally takes. It is a practical guide; the binding terms are in our Terms of Service & Order Terms.

I. What We Need Before We Can Quote

Battery packs are engineered items, not catalogue items. A quotation is only meaningful once we know the electrical and mechanical envelope. The more of the following you can provide, the faster and more accurate the quote:

  • Application — e-bike, golf cart / LSV, power tool, garden equipment, or another device.
  • Voltage and capacity — nominal voltage (e.g. 48V) and energy or capacity (Ah / Wh).
  • Continuous and peak discharge current — this decides the BMS rating and the cell choice.
  • Physical limits — maximum length, width, height, and weight if the pack must fit an existing compartment.
  • Connector and wiring — connector type, discharge/recharge port layout, cable length.
  • Communication — whether the pack must talk to the controller, and over which protocol (CAN, RS485 or Modbus).
  • Certification and destination market — for example UN38.3 plus CE/RoHS for the EU.
  • Quantity — prototype units and expected annual volume, quoted separately.

If you only have a drawing, a photo of an existing pack, or a device specification, send that instead. We routinely work from a sample or a 3D file.

II. Step 1 — Send Your Requirement

Use the request a quote form and attach a drawing or specification (PDF, JPG, PNG, WEBP or ZIP, up to 8 MB). You can also email us directly. We reply to technical and quotation enquiries within 1–3 working days.

Attachments matter: a pack dimension drawing or a photo of the battery compartment removes the single most common cause of a wrong first quote.

III. Step 2 — Technical Review and Quotation

An engineer reviews the requirement for feasibility: cell selection (Samsung, Panasonic, EVE or ATL depending on the duty cycle and budget), BMS architecture, thermal layout and mechanical fit. You then receive a written quotation covering unit price at your quantity, tooling or engineering charges if any, lead time, and the Incoterm we propose.

Minimum order quantity. MOQ is project-based rather than a fixed number. Prototype runs can start as low as 1–5 units so you can test fit and behaviour before committing; production MOQ is quoted separately and depends on the cell and the enclosure. We will always state both numbers explicitly instead of quoting one figure that later changes.

IV. Step 3 — Sample and Approval

After design approval, sample production normally takes 2–4 weeks. Samples are shipped with their test record so you can verify capacity, discharge behaviour and communication before approval.

One to three sample rounds is normal. Mechanical fit issues and firmware or protocol tweaks usually surface in the first round; changes requested at this stage are far cheaper than changes after tooling and production.

V. Step 4 — Order Confirmation and Payment

Once parameters, quantity, price, delivery cycle and payment method are agreed, we sign a formal order contract — confirmed online or signed and sealed offline. Payment follows the advance payment plus final payment structure set out in the order contract; the exact proportion is agreed per order rather than fixed by this page.

Production is scheduled from the date the parameters are confirmed and the corresponding payment is received. This is why the production clock does not start on the day of the enquiry.

VI. Step 5 — Production and Inspection

Mass production normally takes 3–6 weeks after sample approval. Every pack is assembled from tier-1 branded cells and tested before shipment; the inspection record travels with the shipment.

This production window covers manufacturing only. Freight and customs transit are additional — see Shipping & Order Tracking for how transit time is estimated.

VII. Step 6 — Shipment and Documentation

Lithium batteries are regulated dangerous goods (UN3480 for cells and packs shipped alone, UN3481 when packed with or contained in equipment). We prepare the transport documentation — UN38.3 test summary, MSDS, and the dangerous goods declaration appropriate to the mode — and handle export documentation. Door-to-door delivery is available worldwide.

VIII. What Can Delay an Order

  • Late parameter confirmation — every change after sample approval restarts part of the engineering review.
  • Late advance payment — the production slot is held but the clock does not start.
  • Certification — a UN38.3 test on a new pack design typically takes a few weeks and runs in parallel with, not before, the sample build.
  • Destination import rules — some markets require additional registration or a local responsible party before lithium batteries can be imported.

If any of these affect your order we tell you as soon as we know, with a revised date, rather than letting the original date quietly slip.
