VoltR has secured €22m in combined financing to move its lithium-battery remanufacturing model from pilot scale into a larger French industrial operation. The package comprises €16m of Series A equity from Bpifrance's SPI 2 Fund and Decathlon Pulse, plus €6m of grants through the Première Usine programme.
The company says it has already placed more than 20,000 batteries on the market. It now plans to double the footprint of its Verrières-en-Anjou factory, increase production capacity sixfold within two years and add about 40 roles, doubling its workforce. The funding will also support automation, cell-diagnostic and reassignment technology, and a regulated storage site for used batteries.
Turning variable waste into a repeatable product
VoltR does not simply recycle cells for raw materials. Its process starts with collecting used battery packs, then testing and characterising individual cells before grouping them by remaining performance and assembling them into new packs. VoltR says it supplies standard and custom batteries for light mobility, power tools and other electronics, and energy-storage applications.
That model makes diagnosis and matching the centre of the factory economics. Incoming cells arrive with different usage histories and levels of wear, while customers still need certified packs built to a defined power, capacity and lifetime specification. Automating the sorting and reassignment steps can raise throughput, but only if VoltR can secure enough suitable used batteries and keep demand growing for the resulting products.
The company points to concrete routes into both sides of that equation. Its official case studies include a Leroy Merlin rollout across 140 stores, batteries for refurbished La Poste e-bikes and storage systems for Solamaz. These are company-supplied examples rather than disclosed revenue figures, but they show how the same cell-recovery capability can serve several markets without requiring VoltR to manufacture the end product.
Financing the move from proof to capacity
The mix of equity and grants reflects the capital demands of that transition. The equity gives VoltR risk capital for automation and commercial expansion; the Première Usine support helps fund an industrial project with wider supply-chain and environmental objectives. Bpifrance brings factory-scale investment experience, while Decathlon Pulse offers knowledge of product use cases and distribution. No supply agreement with Decathlon was disclosed, so its participation should not be read as a customer commitment.
VoltR's previous step was a €4m first funding round announced in April 2024. It later announced a small-electric-mobility battery partnership with Valeo. The new package is therefore a larger industrial test: whether a process demonstrated across early products and partnerships can operate at six times the capacity without cell quality, collection logistics or customer qualification becoming the constraint.
