Second-life lithium cells and BMS, tested and ready to use

Everything you need to assemble your battery packs: second-life 18650 and 21700 cells (LFP & NMC) recovered from end-of-life battery packs, tested one by one and sorted by grade, plus our 12 V to 48 V BMS. Add to cart and order online.

Understanding our cells

Our cell grades

Each cell is graded by its actual state of health (SOH), measured cell by cell on a test bench. Below 70% SOH, a cell is never resold — it goes to material recycling.

GradeSOH (state of health)Recommended use
A≥ 90%Premium pack assembly, high-demand applications.
B80 – 90%Stationary storage, solar self-consumption.
C70 – 80%Low-demand storage, backup power.

Full traceability via QR code

Every cell carries a unique QR code linking to its record in our database: measured capacity, internal resistance, SOH, chemistry and origin. You know exactly what you're buying, cell by cell.

Second-life cells, not new

Our cells come from disassembled battery packs, then tested one by one. They may show slight soldering marks (nickel spots) on the electrodes: this is a purely cosmetic detail, with no impact on the cell's performance or safety.
