From first cell to series,
without changing address.
The scaling ladder that makes AMPHOUR the last supplier decision a program has to make.
Four stages.
One platform.
The line that runs your A-sample is the line that runs your up-to-100 MWh series — no requalification between stages.
Research & Prototype
Campaigns from as little as 1 MWh. A-grade cells from the first run, not the hundredth.
Move up when the cell design is stable and A-grade output repeats.
Sample Phases (A/B)
A-sample and B-sample campaigns built for program qualification, not for a lab demo.
Move up when A/B samples clear your program qualification gates.
Ramp-up
Pilot-scale campaigns that prove the line before you commit to series.
Move up when the pilot line proves yield and consistency at rate.
Series Production
Modular lines, changeover in days — not months — between campaigns.
Full series — modular lines run campaign after campaign.
Changeover in days,
not months.
Modular minienvironment lines reconfigure between campaigns without rebuilding the floor. The line that ran your A-sample is the line that runs your up-to-100 MWh series.
- Campaigns from 1 MWh. Batch sizes most manufacturers won't take — one of our USPs.
- Customized supply chain. Tuned per program, from 100% local to partially local.
Same modular lines, A-sample to series. Changeover in days.
Where "we can actually
produce this" gets proven.
Battery production under German operation and as local as you want — from supply chain through cell assembly to system assembly.

What are the stages of AMPHOUR’s production ladder?
AMPHOUR scales across four stages on one modular platform: research and prototype (from 1 MWh), A/B sample phases, ramp-up, and series production.
What is the smallest campaign AMPHOUR will run?
AMPHOUR serves campaigns from as little as 1 MWh — a USP, since that batch size is too small for most manufacturers — and scales the same platform up to series.
How local is AMPHOUR’s supply chain?
AMPHOUR offers a customized supply chain, tuned per program from 100% local to partially local, alongside a one-way data flow that keeps customer IP inside the entity.
