05 / Manufacturing evidence
See the process. Review the record.
Real workshop and equipment photography provides manufacturing context. For an order decision, ask which records relate to your battery design, sample revision and acceptance criteria.
- Requirements & design
- The agreed application needs, battery definition and relevant drawings.
- Sample & validation
- Prototype status, test scope and the available records for that revision.
- Build & release
- Assembly information, quality criteria and open items before production.
The review package is agreed per project; availability and disclosure of individual records are confirmed during project review.
06 / Production readiness
Make the release decision explicit.
Before moving from a sample to production, align the product definition, the evidence to review and the remaining decisions. A design change should be reflected in the relevant build and inspection information.
Define the build
Review the design revision, bill of materials and assembly information needed for the agreed scope.
Review readiness
Confirm sample status, validation findings and the resolution of open items. A pilot build may be included where required.
Agree release & changes
Confirm release conditions, responsibilities and how subsequent changes will be reviewed.
Order preparation
Packaging & delivery readiness
Packaging is part of the project definition. Product protection, terminal protection, labeling and transport documentation need to match the battery configuration and planned shipment.
Packing method, transport requirements and delivery arrangements are confirmed for the specific order.

Compliance support
Plan for the market. Check the scope.
Certification requirements are evaluated during project development and incorporated into design and validation planning. The destination market, application and battery configuration determine what needs review.
Applicable documents and their relevance to your configuration are confirmed during project review.
- Market & application
- Identify the destination, host product and intended operating conditions.
- Relevant documentation
- Check the document owner, covered model, scope, date and applicable conditions.
- Project-specific plan
- Agree which evaluations or documentation are needed and who is responsible for each step.
Questions before production
A clearer starting point.
How does a custom battery move from design to production?
Start with the agreed battery definition and application requirements. The project then defines the component selection, assembly route, inspection points and functional test scope. Sample findings and open issues are reviewed against the release criteria before production proceeds.
What quality checks should be defined for a battery pack?
Depending on the design, the scope may cover incoming materials, assembly connections and insulation, electrical behavior, mechanical fit, functional verification and final review. The methods, acceptance criteria and records are defined according to project requirements.
What does an equipment photograph tell me about validation?
A photograph shows the equipment or setup visible in the image. It does not establish that a specific battery passed a test. Product validation requires a record identifying the sample revision, method, conditions, acceptance criteria and result.
What can I review before placing a production order?
Discuss the agreed requirements, battery definition, relevant drawings, sample status, validation plan, available manufacturing evidence and documentation package. The review scope and availability of each record are confirmed for the project.
How is certification and compliance support planned?
The destination market, application, battery configuration and shipment requirements are reviewed during development. Any proposed report or certificate needs to be checked for its owner, covered model, scope, dates and relevance. Requirements and responsibilities are agreed for the specific project.
What information should I send for a manufacturing review?
Share the application, electrical requirements, installation space, interfaces, operating environment, project stage and expected volume. Include available drawings and any validation, certification or packaging requirements through the Technical RFQ.
