Eleven Molicel cell models in the catalogue now carry the manufacturer's own product data sheet as a downloadable PDF, filed against the model page with the document version printed on the file. The set covers the 18650 M and P series and the 21700 P series, and it is the only brand on this site where every listed model has an original manufacturer document behind it.
What was filed
The data sheets are the manufacturer's PDFs, not reseller summaries or a table we typed up. Each one is linked from the Downloads panel on the matching product page, and the version number is shown where the document prints one.
| Model | Format | Document version |
|---|---|---|
| INR18650-M30A | 18650 | not printed on the file |
| INR18650-M35A | 18650 | v1.4 |
| INR18650-P22S | 18650 | v1.0 |
| INR18650-P26A | 18650 | v1.4 |
| INR18650-P28A | 18650 | v1.3 |
| INR18650-P30B | 18650 | v1.0 |
| INR18650-P30S | 18650 | v1.1 |
| INR21700-P42A | 21700 | v1.7 |
| INR21700-P45B | 21700 | v1.2 |
| INR21700-P50B | 21700 | v1.1 |
| INR21700-P50S | 21700 | v1.1 |
Every value quoted on those product pages — capacity, continuous discharge with its cut-off condition, charge current, impedance — is taken from the document in that row. Where the manufacturer states a condition next to a rating, the condition stays on the page, because a rating without its condition is not something you can design against.
One file name to be aware of
The P30S document is published by the manufacturer under a file name that contains "21700". The document body gives the model as INR-18650-P30S, and the cell dimensions printed in the same file (18.6 × 65.2 mm) confirm it. We go by the document body, not the file name. If you have been working from the file name and reading that cell as a 21700, the 18.6 mm diameter is the quickest way to settle it.
Why this matters when you order
A data sheet tells you what the cell is rated to do, and the version number tells you whether you and your supplier are reading the same document. Revisions move ratings: a later revision of a power cell can change the continuous discharge figure or the temperature cut-off attached to it. When you send us a model for quotation, we quote against the document we hold and tell you which version it is. If your design is built on a different revision, say so at that point — the difference is usually a condition rather than a headline number, and that is exactly the part that gets lost in an email thread.
The full set is reachable from the Molicel cell hub, where each row links to the model page and its Downloads panel. The cell catalogue marks the provenance of every value in its Source column: a data sheet badge opens the PDF, a pending badge takes you to the model page where the document can be requested.
What is not covered
Two Molicel models currently on the manufacturer's site — INR21700-P60C and INR21700-M65A — have no downloadable data sheet published. They are not in the catalogue for that reason. When a document appears for them, it will be filed the same way.
