Mission-critical markets — marine, defence, automotive, aerospace, agriculture, industrial.

UKMADE IN BRITAIN

Sovereign capability — design, engineering and manufacturing owned and controlled in the UK.

Anyone can build a battery. We engineer them to last — turnkey systems, designed for manufacture, from concept to consumer-ready. For forward-looking organisations who want the power of certainty in their product.

Markets

Six Markets. One Standard of Reliability.

Made in the UK

Designed and Built in Britain.

From our facility at Unit 1142, Silverstone Park, we design, engineer and build in the UK for the markets that can’t afford compromise. Sovereign capability — owned and controlled here.

Our difference

Custom Where It Counts. Proven Everywhere Else.

We don’t hand you a blank sheet and a big bill. We start from a standard bill of design and a repeatable manufacturing process — engineered elements proven across marine, defence, automotive, aerospace, agriculture and industry — and configure them to your application. You get a pack built for you, without paying to reinvent the wheel.

01

Engineered, Not Bashed Together

A properly engineered pack — not a cheap cell in a box. Our customers put it plainly: theirs don’t fail in the field. That difference is design discipline, testing and interconnect done right.

02

A Standard Bill of Design

Proven building blocks — cells, modules, our BMS, our interconnect — configured to your application. Design it once, optimise it for you. Custom where it counts; standard where it pays. You’re not funding a blank sheet every time.

03

Radically Open

Straight answers on cost, lead time and trade-offs — the positives and the negatives, fast. No proprietary lock-in, no ransom charges, no scope-creep games. You always know where you stand.

04

Nothing Too Hard

No walls, no silly questions. Send us the raw CAD and the problem — we come back with a solution. Concept to delivered hardware in as little as three months.

How we work

Not Wall Decorations. How We Actually Work.

High Regard

Respect for others and believing the best in people. Start with trust, not scepticism.

Transparency

Trusting, sharing, supportive and open. No hidden agendas, no smoke and mirrors.

No Fault Forward

Do what we said we'd do. Learn from mistakes, and move forward.

Continual Improvement

Always a better way. Curiosity in excellence, embracing change.

Extreme Ownership

See it — own it — fix it. No sloped shoulders, no them vs us. One team.

Track record

Delivered, in the Field.
