Lemonergy Data API.
Battery information for your tools.

Search battery products, retrieve complete specifications and keep the source evidence in your engineering workflow.

The open reference

Free data library

Need the files directly? Download the public battery records from GitHub, with their source references. API access and account management belong to Lemonergy.

  • Battery cells, modules, packs and systems
  • Original units, test conditions and source references
  • Electrical component and patent research, with review status
  • No account or payment needed to use the data

API reference

The endpoints for your workflow.

These routes are implemented in the private Lemonergy backend. Production activation is in progress; access is not available for purchase yet.

GET /api/data/v1/batteries

Search accepted battery cells, modules, packs and systems.

GET /api/data/v1/products

Search the complete accepted product catalog. Filter by manufacturer, model text, product kind or a measurement in its original unit.

GET /api/data/v1/products/{uid}

Retrieve the full record: specifications, measurement conditions, source documents and page references.

GET /api/data/v1/components

Search electrical components once reviewed into the accepted library. Pending research is excluded.

GET /api/data/v1/manufacturers

List manufacturers and their accepted product counts.

GET /api/data/v1/usage

Check your account’s monthly allowance and remaining requests.

A request keeps the source context.

GET /api/data/v1/batteries?manufacturer=Samsung%20SDI&limit=10
X-API-Key: YOUR_PRIVATE_API_KEY

Your key stays on your server. Responses identify the source release and data licence. Follow the returned pagination link to keep a search on the same release. The hosted API requires paid access; the downloadable data remains free.

Keep the engineering context

A rating needs its conditions.

Two capacity figures for the same cell can describe different discharge rates or cutoff voltages. Keep the measurement conditions beside the value when making a comparison.

Follow the source

Know where a value came from.

The library links observations to source documents and page or section references. Missing conditions stay visible, and pending research remains separate from accepted specifications.
