From 100 kWh

Find a BESS manufacturer in China — LFP battery storage sourcing, from 100 kWh

LFP battery storage from residential racks to containerised systems — with BMS, UN38.3 and safety documentation, capacity-verified before shipment.

Energy-storage enclosures during assembly in the factory hall

Battery energy storage (BESS) is increasingly where solar projects live or die, and China dominates LFP cell and system production. We source storage from residential rack systems up to containerised utility-scale units, built on LFP chemistry, from manufacturers we verify rather than re-sellers stacking unbranded cells.

The real risks with storage are over-stated usable capacity, recycled or B-grade cells, a weak or generic BMS, and — critically — missing safety documentation that strands the shipment at customs or fails an insurer. We verify the manufacturer and cell source, confirm usable capacity and BMS spec, and collect UN38.3, IEC and the transport and safety documents the shipment needs before it moves.

Frequently asked questions

How do I find a reliable BESS manufacturer in China?

We identify and vet genuine BESS manufacturers — not re-sellers stacking unbranded cells — through our on-the-ground China network, confirm the cell source and usable capacity, and run the order end to end, so you reach the real producer rather than a trader.

What battery chemistry do you supply?

LFP (lithium iron phosphate) — the standard for safety and cycle life in stationary storage. We verify the cell source so you are not getting recycled or B-grade cells.

Do you provide the safety documentation for shipping?

Yes — UN38.3, IEC 62619 and the transport and safety documents are collected before shipment, because storage that lacks them gets stuck at customs or rejected by insurers.

What sizes can you source?

From 100 kWh residential and commercial racks up to containerised MWh-scale systems, with the BMS and capacity confirmed against your spec.

The risks of sourcing from China — and how we remove them

Every importer faces the same handful of failure points. Here's what each one is, and what we do about it.

1Paying a trader's hidden markup

We verify the supplier is the actual manufacturer and show the factory price separately from our fee, so you never overpay a middleman.

2A 'factory' that turns out to be a shell company

We check business licenses, capacity and history, and visit the site in person before you commit a single payment.

3Losing the deposit to fraud

Funds go to Silk Way Sourcing under one contract, not to an unknown account, and the balance is tied to an inspection you approve.

4Receiving goods that don't match the sample

An independent pre-shipment inspection checks quantity, dimensions and quality against your spec, with a photo report, before anything ships.

5Goods stuck at customs over paperwork

We prepare and handle export and customs documentation end to end, so shipments clear without costly holds.

What importers say after working with us

Sourcing wins across steel, solar, energy storage, construction materials and supplier verification. Client names are withheld for confidentiality.
