Why pick us for custom

The reasons hardware leads tell us they stayed.

Custom is hard. Lots of suppliers will quote it — far fewer will own it through ramp.

One PM, end to end

The engineer who quotes the program also signs off the production routing. No hand-offs.

Pilot ≡ MP

Pilot line uses the same winding, stacking and sealing equipment as MP — process parameters transfer cleanly.

NDA in 1 day

Mutual NDA, no legal back-and-forth. We sign so you can send drawings and BOMs.

Compliance owned by us

UN 38.3, IEC 62133, UL 1642, KC, CE — we file, you receive certificates with shipment.

BOM transparency

You see actual cathode, anode, separator, electrolyte and casing suppliers. No black-box BOMs.

Datasheet within 5 days

Full datasheet (electrical, mechanical, abuse, transport) released with first samples — not after MP.

Customer types

Who runs custom programs with us.

From garage stage to listed companies — we adjust the level of formality, not the engineering rigour.

Tier-1 OEMs

Several long-term consumer-electronics OEM programs running on dedicated MP cells with on-site QA representation and signed quality agreements.

Series-B / C startups

About half our active book. Typical: pre-production hardware, 1–5k MOQ, fast iteration on capacity and BMS.

Medical device makers

ISO 13485-aligned line, DHF and design-control documentation, IEC 60601 leakage testing, full BOM traceability for 10+ years.

Defence / aerospace

Selective engagement only after security review. ITAR-free BOM where required.

Custom-program FAQ

Common questions before kick-off.

What's the minimum order quantity for a fully custom design?

3,000 pcs is the typical custom MOQ once we ramp. For prototypes during the program (A/B/C samples) we accept 100–500 pcs.

Is there an NRE for tooling and design work?

Tooling NRE depends on the geometry; a typical pouch-cell tool is USD 8–15k. Design NRE is usually waived if you commit to a forecast above 50k pcs/year. We'll be transparent in the feasibility quote.

Can you sign a quality agreement?

Yes — standard for medical and key OEM customers. We use either your template or our IATF-aligned template, signed before MP starts.

Do you support second-source qualification?

Yes. If we're your second source we will match drawings exactly and run a 4-week qualification including dimensional, capacity, IR, abuse and cycle. We don't ask to redesign.

What if my volumes are smaller than 3,000 pcs?

Below MOQ we can keep the program on the pilot line with a per-piece adder. We've run continuous 500-pcs/month medical programs that way for years.

Have a CAD file ready?

Upload it with your inquiry and we'll return a DFM proposal within 3 working days. NDA available before any drawing exchange.
