Europe's power is critical.
Its cells shouldn't be imported.
Amp-Hour is Europe's dual-use battery cell foundry — sovereign production in Germany where your cells are built, from a single 1 MWh campaign up to series, without building your own factory.
A chip has its foundry. Now the cell has one too.

- 01CreationLocal production of the battery cell & system — built in Germany, not imported.
- 02ApplicationProven cell & module catalogues, applied to your program. No base development — only sovereign application.
- 03HandlingCapability flows in; your IP & data never flow out — one-way, inside one German entity.
Three programs.
One production floor.
You don't need a battery company. You need a cell manufacturer who understands what you're building it for.
UAV & Unmanned Mobile Systems
Every gram matters in the air. Cells for drones and unmanned mobile platforms, produced to the tolerances these systems demand.
Special Vehicles
Secondary batteries for special vehicles — engineered to your chemistry, your form factor, your qualification. Not the traction battery.
Stationary Power Supply
Battery containers and cabinets for fixed installations — uninterrupted power, charging solutions and directed-energy systems, engineered into the site.
One partner, one facility,
every stage.
No serious program bets on a supplier who can only do one phase. We do all four, on the same platform — no requalification between stages.
- S1
Research & Prototype
From 1 MWh · A-gradeCampaigns from as little as 1 MWh. A-grade cells from the first run, not the hundredth.
- S2
Sample Phases (A/B)
Program qualificationA-sample and B-sample campaigns built for program qualification, not for a lab demo.
- S3
Ramp-up
Up to ~30 MWh/yrPilot-scale campaigns that prove the line before you commit to series.
- S4
Series Production
Up to ~100 MWh/yrModular lines, changeover in days — not months — between campaigns.
Same platform, first sample to full series. You don't start over when you scale up.
Your IP never leaves the building.
The building is in Aachen.
We produce your cells in Germany, under German jurisdiction, with a supply chain you tune from 100% local to partially local — sovereignty on your terms, not a slogan.
Capability flows in. Customer data never flows out. Your requirement, your chemistry, your production data — contractually and architecturally, they stay inside this entity. Nowhere else.
- German Entity
- CELLOVATE GmbH — German management, German facilities, German jurisdiction, in Aachen.
- One-Way Data Flow
- Capability comes in; your data never leaves.
- Customized Supply Chain
- From 100% local to partially local — tuned to your program.
Produced in Germany · CELLOVATE GmbH, AachenWe tell you this
before you have to ask.
Serious procurement runs diligence on every supplier. We'd rather you heard our structure from us than found it later.
Amp-Hour operates as an independent German entity — separate branding, separate systems, separate data infrastructure from any affiliate. Customer IP, program data, and production records never leave this entity, by contract and by architecture. That's not a claim. It's how the building is wired.
Your competitor may share a hallway with someone we work with. They will never be in your data.
What buyers
actually ask.
What is Amp-Hour?
Amp-Hour is Europe's dual-use battery cell foundry — a company that engineers and produces battery cells in Germany, from a single 1 MWh campaign up to series production, keeping each customer's chemistry, form factor and intellectual property under German control.
What is a battery cell foundry?
A battery cell foundry manufactures battery cells to a customer’s own design and specification — the way a semiconductor foundry manufactures chips designed by others — so the customer keeps the intellectual property while the foundry provides the sovereign production capacity.
Where does Amp-Hour produce its cells?
Amp-Hour produces its cells in Germany, operating as CELLOVATE GmbH, an independent German-registered entity in Aachen, under German jurisdiction.
What applications does Amp-Hour serve?
Amp-Hour produces cells for three dual-use application categories: UAV and unmanned mobile systems, special vehicles, and stationary power supply — the last covering uninterrupted power supply, charging solutions and directed-energy systems.
Can Amp-Hour build cells to my own chemistry and qualification standard?
Yes. Amp-Hour engineers cells to the customer’s chemistry, form factor and qualification target, from prototype through series production, rather than supplying a fixed catalogue product.
What is the smallest order Amp-Hour will produce?
Amp-Hour serves campaigns from as little as 1 MWh — batch sizes most manufacturers will not take — and scales the same platform up to series production.

No sales funnel, no form-fill maze. A named engineer reads every request.
