Interested in our stock of cells?
We supply professionals with tested, sorted and documented second-life lithium-ion cells. Reconditioners, pack assemblers, integrators, repair shops — let's talk volume, chemistry and grade.
Measured cells, not cells sold “by weight”
We disassemble end-of-life mobility and EV batteries, then characterise every cell before offering it. You receive qualified material, with its data.
Cylindrical 18650 & 21700
LFP and NMC chemistries, from scooters, e-bikes, mopeds and EV packs. Other formats on request.
Tested one by one
Real capacity (Ah), internal resistance (mΩ), SOH and a safety check measured cell by cell on a test bench.
Sorted and matched
Grouped by SOH, capacity and chemistry into homogeneous batches, ready to use in assembly.
Documented & traceable
A measurement sheet per batch, chemistry and origin. You know exactly what you build into your products.
A grade for every use
Cells are graded by their real state of health. Below 70% SOH they are not resold — they go to material recycling.
| Grade | SOH | Typical use |
|---|---|---|
| A | ≥ 90% | Premium pack assembly, heavy duty |
| B | 80 – 90% | Stationary storage, solar self-consumption |
| C | 70 – 80% | Low-duty storage, backup power |
A supplier that measures before selling
- Cell-by-cell sorting. No cell enters a batch without being characterised on a charge/discharge bench.
- A standards-aligned process. Our batteries are tested to meet EN IEC 62619:2022, CE marking and UN 38.3.
- Regular volumes. A steady flow of cells from our collection activity, for recurring supply.
- Based in France. Workshop in Grenoble, a dedicated technical contact, European logistics.
