Send an Inquiry

A quotation for a custom lithium battery pack starts from your device, not from a catalogue. The more you can tell us about the application, the electrical requirements and the physical space available, the faster we can confirm a configuration and put a price against it. Inquiries that arrive with a complete picture move through engineering review without a round of clarifying questions.

Include these items in your first message:

• Device and application — what the pack powers and how it is used, so the duty cycle and safety context are clear.
• Available space or drawings — enclosure dimensions, mounting points and any connector positions already fixed.
• Target voltage and capacity — the voltage class you need and the capacity your runtime target requires.
• Continuous and peak current — both figures, since they drive cell selection, protection board rating and tab design.
• Operating environment — temperature range, vibration, ingress exposure and charging conditions.
• Estimated quantity and target market — annual volume and the destination market, which determine the document set the order needs.

If you have a working spec from a current supplier, attach it. A like-for-like brief is often the quickest path to a comparable design. Where the space and the electrical requirement contradict each other, our engineers will say so early and propose alternatives rather than quote around the conflict.

For the configuration logic that sits behind a pack — how series count sets voltage and parallel count sets capacity — the custom battery packs page explains what a build covers. If the mechanical envelope is still open, the design service page sets out how a pack is developed from your device requirements through to the specification. Both pages are useful background to send to colleagues before an inquiry is filed.

Contact Details

Email: sales@customlithiumbatterypacks.com. Phone / WhatsApp: +86 13924645656. The sales and engineering team works from Shenzhen, Guangdong, China, and corresponds in English — email, WhatsApp and the inquiry form on this page all reach the same team.

The inquiry form asks for your name, email and message. Treat the message field as the place to paste the checklist above: a short application note plus your voltage, capacity and current requirements, and any drawings in text form. Attachments that cannot be sent through the form can follow by reply once the thread is open.

We are a manufacturer working with OEMs and importers, not a retail channel. Orders are project-based: custom packs are built to a confirmed specification, and items held in stock ship directly. That means the useful conversation starts with your requirements, not with a part number. Buyers who arrive with a full brief move straight into engineering review; buyers who send a one-line request should expect one reply asking for the missing items.

Our quality and environmental management sit under ISO 9001 and ISO 14001 certified systems, and the company holds National High-Tech Enterprise status with multiple utility model patents. Documentation for a specific model — UN38.3, IEC 62133 and MSDS — is confirmed per model, so name the model you are buying and we will tell you which documents cover it.

Frequently Asked Questions

How fast will we get a quotation?

The first response runs on the completeness of the brief: a message carrying the device application, space, voltage and capacity, current figures, environment and estimated quantity can be reviewed against the engineering checklist straight away. Incomplete inquiries receive a reply asking for the missing items before a price is quoted.

What should we include in our first inquiry?

Send six things: the device and how it is used, the available space or drawings, target voltage and capacity, continuous and peak current, the operating environment, and estimated quantity with the target market. These let engineering select a configuration and check it against your current profile and enclosure before quoting. If you hold a specification from an existing supplier, include it. For general questions not tied to a quotation, the FAQ page covers documentation and order terms.
