Start designing custom packs for e-bikes, e-motos, drones, robotics, and one-off builds
Create a free account to trace the enclosure, plan the cell layout, preview spacers, cases, and busbars, and export CAD-friendly files from the same workspace.
Best fit today: irregular custom geometries where packaging and manufacturability matter. No credit card required.
Frame-fit e-bike packs
Plan around triangle cavities, central frame volumes, service lids, and connector exits before you print or machine anything.
Drone and payload packs
Useful for endurance packs, constrained battery bays, and custom payload power modules.
Live 3D validation
See your pack from every angle, verify clearances, and catch issues before you export.
Case, spacer, and busbar outputs
Exports that match the preview. Generate STL/STEP, optional DXF, and a JSON manifest.
Safety first
Battery systems can be dangerous if improperly designed, assembled, or used. BatteryBee provides estimates and exports, not guarantees. You are responsible for validation, protective circuits, and compliance. The full disclaimer and agreement appear in the sign‑up form.
What you can export once the layout is ready
- ✓Case body and lids as STEP/STL
- ✓Optional spacer STLs and (when enabled) DXF outlines
- ✓Busbar DXF when busbar layers are configured
- ✓JSON manifest with key parameters and layer summaries
- ✓Fabrication README (units, orientation, lid parameters)
Why DIY builders pick BatteryBee
Freeform geometry
Irregular outlines are first-class. Design around cavities, keep-outs, and service access from the start.
Layer‑aware planning
Multi‑layer packs with spacing rules and per‑layer visibility for quick checks.
Export parity
What you export matches the geometry you validated in the 3D viewer.
