Vancouver / Richmond, BC · Battery Commercialization Partner

Source advanced battery
technology from China — with confidence.

We help global pack builders discover, evaluate, and bring in qualified Chinese cell technology — starting with a deep, direct relationship with one manufacturing partner, not a marketplace of unknowns.

Why it's hard — The Sylva Gap

Sourcing cells from China isn't the bottleneck.
Trusting what arrives is.

Pack manufacturers outside China don't struggle to find a factory — they struggle to find one they can verify, communicate with in real time, and hold accountable after the invoice is paid.

Language & Distance

Specs get lost in translation

Datasheets, tolerances, and quality flags don't always survive the trip from a Chinese factory floor to a foreign engineering team — and by the time the gap surfaces, the cells are already on a boat.

Compliance

Missing paperwork stops shipments cold

UN 38.3 test summaries, MSDS, and CO get requested after the fact more often than they should. Without them, cargo sits at customs — or worse, doesn't clear at all.

Continuity

Most cross-border deals start with one unverified factory

A cold-outreach relationship with a single, unaudited factory is a fragile foundation for a production line. We start every relationship with real diligence — not a WeChat introduction and a deposit request.

How we help — The Thermal Core

We reduce the risk in a decision
you'd otherwise be making blind.

We're not a marketplace and we don't move volume through a warehouse. We work one relationship at a time — helping you find the right technology, verify it's real, and get it landed correctly.

01

Discover

We match your chemistry, form factor, and volume requirements against what our manufacturing partner actually produces — no generic catalog dump.

  • Application & spec intake
  • Chemistry & form-factor matching
  • Honest fit/no-fit assessment
02

Evaluate

We do the supplier due diligence and technical review your team doesn't have a China-based person to do — so you're deciding on evidence, not a sales deck.

  • Supplier due diligence
  • Technical & datasheet review
  • Testing coordination with the factory
03

Coordinate

Certification isn't something we issue — it's something we coordinate, chasing the factory for the right paperwork before it becomes your problem at customs.

  • UN 38.3 documentation coordination
  • Certification coordination (UL, IEC, etc.)
  • Pack configuration input, coordinated with the factory
04

Deliver

We manage freight and the factory relationship end-to-end, with a founder you can actually reach — not a ticket number.

  • Freight coordination, sea & air
  • A direct point of contact in Canada
  • Ongoing account management
Current manufacturing partner

One partner, chosen deliberately —
not a list padded for effect.

We work directly with a single manufacturing partner today. We'd rather show you one relationship we can actually stand behind than a wall of logos we can't.

Talent New Energy (太蓝新能源)
Chongqing, China

Talent New Energy is our current strategic manufacturing partner for advanced battery technologies. We selected them for three reasons:

01

Real chemistry, not a slide deck

Semi-solid-state and anode-free cell lines with an established product catalog — production we could inspect, not a roadmap.

02

Prior overseas experience

Existing work on international UAV and specialized-vehicle programs, so shipping outside China isn't a first for them.

03

A relationship we can verify directly

Our founders have direct contact with their team — not an intermediary, not a trading company standing between us and the factory floor.

We're in the process of qualifying additional manufacturing partners. As that happens, they'll be added here with the same diligence — not appended to a list to make the network look bigger than it is.

Catalog shown reflects our current manufacturing partner, Talent New Energy. LMB = lithium-metal battery. AFB = anode-free battery. SSB = semi-solid-state battery. Don't see the form factor or chemistry you need — pouch, cylindrical, prismatic, other capacities? Tell us your spec and we'll tell you honestly whether it's something we can source.

Applications we support

Built for platforms where weight,
temperature range, and pulse power matter.

Our current catalog is concentrated in a few demanding categories — not a general-purpose cell list. If your platform falls outside these, tell us anyway; we'll say so honestly if it's not a fit yet.

UAV & eVTOL

Specialized and long-range UAV platforms — our deepest current coverage, from 11Ah to 50Ah.

Energy Storage (ESS)

Semi-solid-state chemistry suited to stationary and mobile storage applications.

Marine

Cold-tolerant chemistries (down to −40°C) suited to marine and cold-climate deployments.

Robotics

Compact high-discharge cells for humanoid and quadruped platforms, 8.8Ah–13Ah.

Special Vehicles

Heavy-load and pulse-discharge cells for demanding ground vehicle platforms.

How we work — The Ignition Sequence

From first call to running line.

A fixed sequence, not a black box — you know what's happening at every stage of the relationship.

01

Discovery call

We take your cell spec, volume forecast, and timeline, and tell you honestly whether our current manufacturing partner can meet it — no generic RFQ blast.

02

Samples & technical review

You receive samples along with translated datasheets and our own technical review notes, not raw marketing decks.

03

Compliance coordination

Before any purchase order is placed, we coordinate with the factory to confirm UN 38.3, MSDS, and CO documentation is complete and matches the actual production batch.

04

Order & logistics

We manage the PO, freight booking, and customs handoff — with a Canadian point of contact you can reach during your own business hours.

05

Ongoing account management

Repeat orders and early notice of any factory-side disruption — for as long as the cell is on your BOM.

Compliance, by default — Bedrock Compliance

We don't sell you the cell.
We sell you the paper trail behind it.

Transport Canada's own testing found that half of sampled third-party replacement lithium batteries failed UN 38.3 — some catastrophically. We built our process around that exact failure point.

UN 38.3 test summaries, verified against batch

We confirm the test summary corresponds to the exact production run being shipped — not a general certification for the product line.

Full documentation package, before departure

MSDS, certificate of origin, and transport declarations are assembled and checked prior to the cargo leaving the factory.

A record you can hand to your own QA team

Every shipment comes with a documentation file your compliance or engineering team can audit independently.

Documentation gaps are the single most common reason third-party cell shipments stall at customs. We check before you commit, not after the shipment is stuck.
Request your requirement

Tell us what you're building.
We'll tell you honestly what we can do.

Five fields, not a sales funnel. We'll come back with a real answer — including "not a fit yet" if that's the honest one.

The SylvaGrid Standard

We don't just ship cells. We ship certainty.

Three commitments that hold on every order, regardless of factory, chemistry, or destination port.

Chosen, not padded

Our manufacturing partner is diligenced and re-checked on an ongoing basis, not onboarded once and forgotten.

Coordinated, not slow

Sourcing, QA, and logistics run as one coordinated process — not three handoffs that each add a week.

Honest, not fragile

Documentation, a direct point of contact, and a straight answer when something isn't a fit — the foundation stays solid because we don't overreach.
