Dongguan Hemax New Energy Co., Ltd. develops customized OEM/ODM lithium-ion battery packs for applications including stair-climbing machines, logistics AGVs, drones, robots, energy storage, mobility, smart homes, medical devices, and industrial equipment. For buyers preparing to discuss a new project, one question deserves attention before detailed files change hands: Does a Custom Battery Pack Manufacturer Sign an NDA?
Yes—some custom battery manufacturers explicitly offer to sign non-disclosure agreements before discussing confidential projects. However, buyers should confirm each supplier's policy rather than assume that protection applies automatically.
From an engineering procurement perspective, the signature is only the starting point. A useful NDA should define what information is protected, how the manufacturer may use it, and who may access it. Equally important, the supplier's everyday handling of drawings, samples, and technical discussions should support those obligations.
A manufacturer may sign an NDA before preparing a detailed quotation, particularly when accurate pricing requires proprietary drawings, battery management system specifications, or product integration details.
Not every introductory conversation needs sensitive information. Buyers can often begin with general requirements:
- Nominal voltage and target capacity.
- Continuous and peak discharge current.
- Approximate installation space.
- Operating temperature range.
- Estimated order volume and development schedule.
- Intended application and target markets.
These details help establish whether a supplier is technically suitable. However, even basic specifications can be sensitive when they reveal an unreleased product concept.
My practical recommendation is to separate supplier screening from engineering disclosure. First establish capability and commercial fit. Then agree on confidentiality before releasing information that would materially help another company reproduce your design or anticipate your launch.
A custom battery pack is more than an arrangement of cells. Its commercial value may sit in the relationship between electrical performance, mechanical integration, software behavior, and operating conditions.
A logistics AGV battery specification, for example, may reveal charging windows and operational duty cycles. A drone battery project may expose weight constraints and power requirements. A medical equipment battery may disclose integration details for an unreleased device.
Depending on the project, confidential material may include:
- Cell selection criteria and approved alternatives.
- Pack layouts, enclosure CAD files, and connector arrangements.
- BMS schematics, firmware, and communication protocols.
- Protection thresholds and charging strategies.
- Thermal designs and validation results.
- Bills of materials, assembly methods, and inspection criteria.
Forecast volumes, target prices, customer identities, launch schedules, and supplier arrangements can be commercially sensitive.
An NDA should therefore address relevant technical and business information. Protecting a drawing while leaving its associated quotation, test report, or development discussion outside the agreement can create an avoidable gap.
A useful agreement should be understandable to the people who must follow it. Broad language alone is not a substitute for clear obligations.
| NDA element | What buyers should clarify |
|---|---|
| Contracting parties | The legal entities providing and receiving information |
| Confidential information | Covered documents, samples, software, discussions, and derived materials |
| Permitted purpose | Activities such as evaluation, quotation, development, testing, or manufacturing |
| Access restrictions | Which employees, affiliates, advisers, and subcontractors may receive information |
| Exclusions | Information legitimately public, already known, independently developed, or lawfully received |
| Duration | Disclosure period and continuing confidentiality obligations |
| Required disclosure | Procedures for legally compelled disclosure, where permitted |
| Project closure | Return, deletion, retention, and treatment of physical samples |
| Dispute provisions | Applicable law, dispute process, and available remedies |
Avoid treating a generic template as automatically suitable for every OEM/ODM relationship. A simple feasibility review and a firmware-intensive joint development project can create different risks.
An agreement that restricts disclosure but says little about use may not address the buyer's main concern.
For example, a supplier might need access to a battery enclosure drawing to assess manufacturability. That purpose is different from using the drawing to develop a competing product.
Define the authorized purpose explicitly. Where relevant, discuss restrictions on reverse engineering, copying, benchmarking, or using samples outside the agreed evaluation.
A unilateral NDA generally protects information disclosed by one party. A mutual NDA protects confidential information exchanged by both parties.
A unilateral agreement may fit a project where the customer supplies a complete design and the manufacturer evaluates production.
A mutual agreement may be more appropriate when the supplier also shares proprietary engineering methods, technical proposals, or manufacturing knowledge.
Neither format is automatically stronger. The important issue is whether the obligations match the actual exchange of information.
For collaborative OEM/ODM development, buyers should also distinguish customer-provided specifications from the manufacturer's pre-existing technology. That distinction becomes especially important when discussing ownership later.
One of the most important procurement distinctions is between confidentiality and IP ownership.
An NDA controls the handling of protected information. It should not be assumed to settle ownership of newly developed firmware, tooling, drawings, or manufacturing improvements.
Address those matters expressly in the appropriate development, tooling, licensing, or supply agreement.
Before funding custom engineering, ask:
1. Who owns the original design files?
2. Who owns project-specific modifications?
3. Is existing supplier technology incorporated into the solution?
4. What rights does the buyer receive to use or modify that technology?
5. Are source code and editable CAD files included in delivery?
6. Can tooling or technical documentation transfer to another manufacturer?
Payment alone should not be treated as proof that every associated intellectual property right has transferred. Record the agreed allocation clearly.
The strongest approach combines contractual protection with controlled information sharing.
Start with the information necessary to assess capability. Describe performance targets and constraints without automatically sending your complete design archive.
For Dongguan Hemax New Energy Co., Ltd., an initial inquiry can identify the application, electrical requirements, installation envelope, and expected production needs.
Resolve the contracting entity, authorized signatory, protected information, and permitted purpose.
If sensitive information has already been disclosed, ask legal counsel whether and how the agreement should address those earlier disclosures.
Provide progressively more detail as the project advances from feasibility to design, prototyping, validation, and production.
A supplier evaluating cell configuration may not initially need your full host-device software or customer list.
Track what was shared, with whom, when, and for what purpose. Include file versions and any restrictions.
This creates a practical record for engineering coordination and helps prevent outdated documents from circulating.
When a project ends or changes suppliers, review access permissions, retained samples, backups, and contractual retention requirements.
Ask for appropriate confirmation of return or deletion, while recognizing that some records may require lawful or agreed retention.
Battery development can involve outside laboratories, enclosure suppliers, electronics specialists, or other service providers.
The buyer should understand whether confidential material will leave the manufacturer's immediate organization.
Useful questions include:
- Which outside parties need project information?
- What specific information will each receive?
- Is customer approval required before disclosure?
- Are suitable confidentiality obligations in place?
- Who remains responsible for managing those disclosures?
The goal is not to block necessary testing or sourcing. It is to prevent unrestricted onward sharing.
Similarly, confidentiality arrangements should accommodate legitimate safety, regulatory, and legal obligations. An NDA should not be treated as permission to conceal required information or bypass applicable requirements.
Consider a hypothetical AGV developer requesting a battery with a custom enclosure, communication interface, and opportunity-charging capability.
At the screening stage, the developer shares voltage, capacity, current demand, and approximate dimensions.
After the NDA is agreed, the developer provides installation drawings and interface requirements. More sensitive operating data follows only when needed for engineering decisions.
A separate development agreement then addresses ownership of project-specific firmware, tooling, and deliverable files.
This staged approach does two things: it gives the manufacturer enough information to perform useful engineering work, while avoiding unnecessary disclosure before the relationship is established.
This is an illustrative workflow, not a reported customer case or a claim about Hemax's completed projects.
A quick signature is convenient, but it is not sufficient evidence of strong confidentiality management.
Look for clear, consistent answers about:
- Named project contacts and authorized recipients.
- Access-controlled document sharing.
- Document identification and revision management.
- Handling of prototypes and rejected components.
- Subcontractor disclosure procedures.
- Incident reporting and project closure.
Be cautious if a supplier requests complete source files before explaining why they are necessary, or proposes sharing your drawings widely to obtain quotations.
Conversely, a supplier's request to clarify an overly broad agreement is not automatically a warning sign. Clear, workable terms are generally more useful than obligations neither side understands.
For cross-border projects, have qualified counsel assess the contracting entity, governing law, dispute mechanism, language requirements, and practical enforcement considerations.
Dongguan Hemax New Energy Co., Ltd. focuses on customized lithium-ion battery solutions across a broad range of equipment applications.
For a productive first discussion, prepare a non-confidential requirements brief covering your application, voltage, capacity, operating conditions, available space, and expected quantities.
Then request confirmation of the appropriate NDA process before submitting proprietary drawings, firmware, detailed bills of materials, or unreleased product information.
Contact Dongguan Hemax New Energy Co., Ltd. to discuss your OEM/ODM battery requirements and clarify confidentiality arrangements before detailed engineering begins.
The objective is straightforward: share enough information to develop the right battery, while keeping sensitive information within clearly agreed boundaries.
No. Some manufacturers publicly offer this option, but policies and acceptable terms vary. Confirm the supplier's position before sharing sensitive information.
Do so when the quotation requires confidential details. A preliminary discussion may be possible using a limited, non-confidential specification.
It can cover them when the definitions and obligations appropriately include those materials. Confirm whether source code, revisions, samples, and derived documents are also addressed.
Not automatically. Confidentiality and permitted-use restrictions are different from exclusivity. Address any agreed exclusivity separately and define its scope carefully.
There is no universally appropriate period. Consider the useful life of the information, applicable law, and whether qualifying trade secrets need continuing protection while they remain secret.
That depends on the agreement and applicable obligations. Define permitted recipients, necessary safeguards, and any approval requirements before disclosure.
No. An NDA is one protective measure. Limited disclosure, controlled access, documented procedures, and appropriately drafted development agreements also matter.
