A golf cart maker plans a custom lithium pack for a new model. Before sending drawings and performance targets, the product manager asks what confidentiality terms the battery factory should accept.
Sign a non-disclosure agreement before sharing drawings, and agree the points that matter in practice: what counts as confidential, who may see it, how long the duty lasts, what the factory may not do with the information (copy, sell to others, reverse-engineer), and what happens to files and samples when the project ends. Keep the shared information to what is needed for each stage. Have your own adviser review the wording, because law and practice differ by country.
Terms worth agreeing
- Definition. What is confidential: drawings, specifications, firmware, test data and the existence of the project.
- Purpose. The information may be used only to quote and build for you.
- Access. Named teams or roles at the factory, and any subcontractors bound by similar terms.
- Duration. How long the duty lasts after the project ends.
- Return or destruction. What happens to files, samples and tooling when the project stops.
- Ownership. Who owns improvements made during the project. See our OEM versus ODM article.
Practical protection
- Share in stages: outline and interface first, detail only after quotation.
- Mark documents as confidential and keep a list of what was sent and when.
- Agree that any use of your name or images needs written consent.
- Consider local registration of designs or trademarks where relevant to your market.
Redway offers OEM and ODM services and OEM services for custom battery projects; the confidentiality terms for your project are agreed at quotation. Our pilot order article shows what to approve next.
Working with the factory
Ask how the factory separates customer projects, who can access your files and how it handles samples after testing. A clear answer is a good sign of mature practice. Agree the points before any drawing is sent, and keep the signed agreement with the project file.
Risk limits
This article is general information, not legal advice. An NDA is only as good as its enforceability in the relevant country, so take advice from a qualified lawyer.
Additional perspectives
Send an interface drawing and target specification first. If the factory’s response is thoughtful, you can share more; if it is generic, you have shared little.
Redway Tech Editorial Team – Product manager perspective
Prefer a mutual agreement that covers both sides’ information, with a clear definition and a reasonable term. Overlong or one-sided terms slow the project without adding protection.
Redway Tech Editorial Team – Legal counsel perspective
Keep a log of what was shared and with whom, and set a reminder to request the return or destruction of files when the project ends.
Redway Tech Editorial Team – Procurement perspective
Specifications are taken from Redway product pages as of October 2026. Where a figure isn’t published, this article says so. Confirm current specifications for your model with Redway before ordering. This article is general guidance, not a site-specific engineering assessment.
