System Integrators
Cell technology built for integration
Volklec works closely with system integrators to turn high-performance cells into real-world capability — providing the technology, consistency and local support to help you deliver with confidence.
Working with Volklec
From cell to system-ready
Volklec works closely with system integrators to turn high-performance cells into real-world capability. Whether you're developing battery packs, integrating energy systems into complex platforms or navigating the challenges of qualification and supply, we provide the cell technology, consistency and local support to help you deliver with confidence.
Our focus is simple: offering a reliable, UK-based source of high-performance lithium-ion cells that integrates seamlessly into your architecture, scales with your programme and removes the uncertainties associated with overseas dependency.
If you're building the systems that power next-generation technologies, we're ready to work with you.
"A reliable, UK-based source of cells that integrates seamlessly into your architecture and scales with your programme."

What We Offer Integrators
Everything you need to integrate with confidence
01
High-Performance 21700 Cells
Our 21700 lithium-ion cells — the Energy Cell (5.00 Ah) and the Power Cell (CP50/1) — are available to integrators as qualified cell-level components, independently tested and ready to design in.
02
Consistency & Traceability
Every cell we supply comes with full documentation, batch traceability and compliance support — ensuring your qualification process is grounded in data and your supply chain is audit-ready from day one.
03
Application Engineering Support
Our team works directly with yours — helping with cell selection, pack architecture guidance, thermal and electrical integration challenges, and navigating qualification requirements specific to your application.
04
Supply That Scales
We structure our partnerships to grow alongside your programme — from early development samples through to production volumes — so you're never left managing cell supply as a constraint on your delivery.
05
Compliance & Qualification
We support integrators through safety certification, regulatory compliance and evolving requirements — including Battery Passport, Rules of Origin and Extended Producer Responsibility — removing barriers to market entry.
06
Sovereign UK Supply
Manufactured in the UK at UKBIC, our cells eliminate the geopolitical exposure and lead-time uncertainty associated with overseas supply — giving integrators a resilient, origin-compliant source they can rely on.
What We Offer Integrators
Built for the demands of integration
Proven cell format
The 21700 is a recognised industry standard — easy to source housing and hardware for, well understood by thermal and electrical engineers, and compatible with established tooling and test infrastructure.
Independently tested
Both cell variants have been independently tested by About: Energy and Cognition Energy, giving integrators confidence in the data that underpins their design.
Early engagement
We work with integrators early in the programme — helping to shape cell selection and pack architecture before design freeze, rather than entering as a commodity supplier at the end.
Removes supply risk
A domestic, sovereign cell supply removes the geopolitical and logistical uncertainty that integrators face when sourcing from overseas — particularly relevant for defence and critical infrastructure programmes.
