ENGINEERING BRIEF

Good requirements make better decisions.

Jetray’s corporate website describes cell selection, BMS design, prototyping and custom pack services. Use this brief to discuss the scope and feasibility of your own project.

From requirements to review

Make the important interfaces explicit.

A dedicated cylindrical-cell collection for engineers and sourcing teams. Compare form factor, chemistry and documented operating limits before committing to a pack design.

Identify the exact model

A shared size does not make cells interchangeable. Record chemistry, manufacturer and the complete model code.

Compare at matching conditions

Read discharge rate, cutoff voltage and temperature alongside capacity and current ratings.

Protect sourcing continuity

Agree acceptable substitutions, lot traceability and document revision control before repeat orders.

A practical project brief

What to share with the engineering team.

Electrical

Nominal system voltage, allowable input window, continuous current, peak current and peak duration.

Mechanical

Available envelope, fixing points, weight constraints, cable routing, connector and polarity.

Charging & communication

Charger model, charging opportunities, temperature sensing and required BMS or communication signals.

Project & documentation

Intended use, target markets, sample quantities, forecast volume, required test evidence and revision controls.

Project review stages

Keep the decisions and the documents together.

Use these review gates to organize a project discussion with the supplier. The agreed scope and deliverables are confirmed for the individual project.

StageInformation to alignDecision to record
Requirements briefManufacturer model, chemistry and ratings at stated test conditions; Storage conditions, assembly method and equipment environmentThe equipment needs, mandatory limits and open questions.
Configuration reviewIdentify the cell manufacturer, model code, document revision, lot requirements and permitted substitution policy.The proposed model or design scope, interface drawing and document revision.
Sample evaluationRepresentative equipment, operating cycle and acceptance procedure.Results, deviations and changes needed before the next stage.
Order preparationThe approved configuration, quantity, packaging and required shipment documents.The purchase specification, acceptance method and agreed commercial terms.
A useful conversation starts with a specification

Tell us what your equipment needs.

Share the load, dimensions and intended use. Ask for a current model specification and a project review.
