Engineering Support

Tefoo Energy provides engineering-level support for OEM manufacturers, product designers, and procurement teams integrating lithium-ion battery packs into industrial and professional devices. This Engineering Support page outlines the technical resources, documentation scope, and support process available during battery evaluation, system integration, and project development.

Certain technical documents are provided upon request to protect intellectual property and ensure correct application.

For technical documentation, engineering consultation, or project-specific support, please contact our engineering team with the following information:

• Battery model of interest
• Application or device type
• Project stage (prototype, pilot, mass production)
• Expected quantity and timeline

This information allows us to provide accurate and efficient support.

Our engineering team supports customers throughout the full battery integration lifecycle, including:

• Battery pack selection and evaluation
• Mechanical and electrical integration support
• Charger and system-level interface considerations
• Compliance and certification documentation
• Transition from prototype to mass production

This support applies to both standard battery packs and custom battery solutions.

Datasheets provide essential technical information required for engineering evaluation and procurement review.

• Typical datasheet content includes:
• Nominal voltage and capacity
• Charge and discharge characteristics
• Operating temperature range
• Mechanical dimensions and weight
• Protection features and safety notes

👉 Datasheets are available for standard battery pack models. If you need the charger’s datasheet, you can download it from the corresponding charger’s detail page.

To protect intellectual property and ensure correct application, 3D CAD and STEP models of battery packs are provided directly by our engineering team upon request. This process allows us to:

• Verify compatibility with your device and application
• Provide the correct configuration (connectors, cable routing, orientation)
• Avoid misuse of outdated or non-standard models

3D models are typically shared during the engineering evaluation or project development stage.

Usage Context

3D CAD / STEP models are commonly used for:

• Mechanical enclosure design
• Space verification and layout planning
• Design review and integration assessment

Request Guidance

To request a 3D CAD / STEP model, please provide:

• Battery pack model number
• Application or device type
• Project stage (prototype / pilot / mass production)

Tefoo Energy battery packs are designed and manufactured to meet commonly required international safety and transportation standards. Available compliance documentation may include:

• UN38.3 (Transportation safety)
• IEC 62133 (Cell and battery safety)
• CE and RoHS compliance
• Other market-specific requirements upon request
• Certification documents are provided to support:
• Regulatory and compliance evaluation
• Customer qualification and audit processes
• Project documentation requirements

👉 Certification availability depends on the specific battery model.

Selecting a suitable battery pack requires more than matching voltage and capacity. Our engineering team assists with battery selection based on:

• Electrical requirements and peak current
• Mechanical space constraints
• Operating temperature and environment
• Expected cycle life and usage profile
• Charger compatibility and system interface

This guidance helps reduce design risk and shortens development cycles.

Standard battery packs are suitable for many applications with defined electrical and mechanical requirements. However, custom battery solutions are recommended when projects require:

• Unique form factors or size constraints
• Special connectors or cable configurations
• Specific performance targets or lifecycle requirements
• Market-specific regulatory compliance

Our engineering team can advise whether a standard or custom solution is the best fit for your application.
