Beginner mode
Describe the need before you know the part number
Plain-language lookup with datasheet-backed answers and a facts review before you pin a cell.
Guided lookup when you are comparing options for the first time
Ask in plain language
Describe form factor, capacity, voltage, or environment. We translate your sentence into a spec query—no part-number guessing.
Review datasheet facts
Each candidate shows chemistry, geometry, and electrical limits traced to manufacturer documentation—not marketing copy.
Save and revisit
Pin cells, continue the thread later, and export from your dashboard when you are ready to share with the team.
Expert mode
Filter the catalog, then sanity-check pack math
Spec-first filters across chemistry, geometry, and electrical limits—plus an illustrative results table from our indexed catalog.
Spec filters
Filter the catalog by form factor, chemistry, capacity, and continuous discharge—from indexed datasheets.
Saved sessions
Revisit guided lookups and expert filter sets from your dashboard—every answer keeps its sources.
Pack voltage, capacity, and energy computed from the cells you select.
Example expert results
Spec-first filters across the indexed catalog—every row maps to a loaded datasheet.

Expert mode is for engineers who already know their envelope—filter by chemistry, geometry, and electrical limits, then run pack math before you commit a BOM.
How it works
From a sentence to a sourced answer
Three short steps. No spreadsheets. No invented part numbers.
- 01Step 1 of 3
Tell us what you need
Start in Beginner mode with a sentence—form factor, capacity, voltage, environment. We translate it into a spec query.
Open guided lookup - 02Step 2 of 3
We pull from datasheets
Voltaniq cross-references manufacturer documentation across chemistries and form factors—no invented part numbers, no marketing copy.
- 03Step 3 of 3
Compare, save, revisit
Pin candidates, run pack math, and revisit the conversation later from your dashboard. Every decision keeps its sources.
