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

Design-in checkpoint. Ratings are retained from published Jetray catalogue information. Confirm the current model revision and test conditions with the team.
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.
Selection checks for this reference
- Request the pack drawing, lead length and connector pinout for the chosen 3S8P layout.
- Ask which capacity acceptance limit and discharge test apply to the quoted revision. The public 20.8Ah figure is typical capacity.
- Document the controller voltage window and peak demand before confirming the protection board and harness.
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 11.1V 20.8Ah 3S8P 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
The nominal voltage, typical capacity, series-parallel layout and energy are listed in the Jetray catalogue and corroborated by a matching Jetray configuration sheet. Request the current approved connector, protection settings and charge limits for the planned build.
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.
