Specify the cell, not only the size
18650 identifies a form factor. Chemistry, rated capacity, current limits and manufacturer documentation still matter.

Plan the integration
For 18650 battery packs, work through these requirements before finalizing the battery choice.
Review the pack structure
Series and parallel arrangements affect the operating voltage, capacity and protection architecture.
Approve a representative sample
Check the fit, runtime and load behavior using production-representative equipment and agreed test conditions.
Information to include in your inquiry
- Equipment voltage window, continuous load and measured peak current.
- Runtime target, charging system and expected operating temperature.
- Available dimensions, mounting method, connector and cable drawing.
- Sample quantity, forecast volume, target market and required documents.
Ask for model-specific evidence
Request the current electrical specification, a mechanical drawing, protection limits and test conditions. Where required, ask for the exact model’s transport and safety documentation. Confirm the report holder, model scope and revision.
A company certificate, a cell report and a finished-pack report cover different things. The documents need to match the product and its intended use.
Common questions
Is 3.6V 3.5Ah 18650 Battery Pack suitable for my equipment?
The published values are an initial reference. Compatibility depends on the operating voltage window, continuous and peak current, charging system, enclosure and application requirements. Share those details for a model-specific review.
Can I receive a quotation and sample?
Send the reference name and your project specification. The team can confirm the available configuration, sample terms, quantity, price and lead time. No standard MOQ or delivery promise is asserted on this page.
Is the same mAh rating enough to substitute a cell?
No. Confirm voltage limits, current capability, temperature conditions, dimensions and the pack's validated cell model.
Sources & product notes
Values taken from Jetray public listings; request the current approved datasheet before design-in.
Source paths may redirect following the corporate website’s reorganization. Ask Jetray for the current approved model sheet when a legacy page has moved.
Build a complete inquiry
Make your requirements easy to assess.
For 18650 battery packs, the most useful RFQ connects the published reference to the equipment and the project.
01
Electrical & runtime
Exact cell model, series/parallel arrangement and measured load. Include measured peak duration and the target operating time.
02
Mechanical & interface
Protection board, leads, thermistor and pack connector. Add the available dimensions, cable direction and the equipment drawing.
03
Project & evidence
State the sample stage, expected quantities, destination market and documents required for review.
