Define the device context
Describe the intended use, operating environment and the battery's role within the device risk assessment.
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.
Battery selection guidance for medical-equipment development teams. Product references support an engineering discussion; device suitability and compliance require model-specific validation.

Control the interfaces
Confirm electrical limits, protection behavior, thermistor signals, identification and communication as applicable.
Plan model-specific validation
Agree test evidence, traceability and change control with the equipment manufacturer. A catalogue reference is not device approval.
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.
| Stage | Information to align | Decision to record |
|---|---|---|
| Requirements brief | Device voltage window, measured duty cycle and low-battery transitions; Intended device environment, service access and traceability | The equipment needs, mandatory limits and open questions. |
| Configuration review | Record the battery configuration and its interfaces within the equipment manufacturer’s risk management and change-control process. | The proposed model or design scope, interface drawing and document revision. |
| Sample evaluation | Representative equipment, operating cycle and acceptance procedure. | Results, deviations and changes needed before the next stage. |
| Order preparation | The 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.
