Introduction
EV battery production has recently outpaced demand, leaving large volumes of high-quality lithium-ion batteries warehoused and idle. For pack builders, this creates a rare opportunity: tier-1 automotive-grade supply is now available outside the traditional supply chain.
That's why Cling, as an advisory brokerage, gives pack builders direct access to this overstock—no middle layers, no unnecessary friction. Here’s how:
Overstock supply, ready to move
One of the most exciting aspects of this overstock is the quality: unused lithium-ion cells and modules from tier-1 producers that were never deployed, surfacing as surplus and ex-stock. New listings land most weeks, and the available inventory spans various formats and chemistries:
-
Cells: cylindrical, prismatic, pouch with mostly NMC and LFP.
-
Modules: originally built for EVs (OEM overstock) and ESS with mostly NMC and LFP.
-
Packs: automotive and ESS with mostly NMC and LFP.
Whether you're building grid-scale systems or e-mobility packs, this inventory lets you expand your capacity. Of course, "overstock" still means doing your homework — for how to set acceptance criteria for a batch before you commit, see where’s your floor? the blueprint for ESS success. As one North American pack builder put it:
"You are aggregating supply demand for something that is otherwise super high friction and it’s usually very hard to get price discovery or volume discovery. This saves us a tremendous amount of time."
Cutting the complexity
Sourcing batteries traditionally meant juggling specifications, volume, logistics, regulations, and timing across endless email and WhatsApp chains. Working with a desk collapses that workflow:
-
Aggregated supply – surplus and ex-stock listed as found, with quantity, chemistry, level and region, so you can compare like with like.
-
Enquire, then the desk runs the deal – you flag what fits and we handle qualification, contracting and negotiation; pricing is quoted against your actual requirement.
-
Structured terms & dangerous-goods logistics – every deal closes on a contract with an inspection window and a documented claims process, with UN38.3, ADR/IATA and cross-border compliance (EU Waste Shipment Regulation, Basel, EPR) handled.
The aim: far less time from “need batteries” to “batteries shipped.”
Move now
Pack builders who move now will secure cost-effective, high-quality batteries and gain a competitive edge before supply tightens again - while contributing to a more efficient, circular battery value chain.
