Capability

What the plant actually runs

Cell to pack, in one building

Cells are graded and matched on site, then assembled into packs with the BMS fitted on the same line. That is why capacity figures stay consistent between containers.

17 automated lines

Spot welding, screw driving, dispensing and testing are automated where it matters; the visual checks stay with people.

500,000 units a month

Monthly capacity across portable, home backup and industrial cart models. Peak season requires a booking 4–6 weeks ahead.

In-house safety testing

Overload, over-temperature, short circuit, drop and burn-in under load before the packing line.

Preshipment inspection

Carton, label, accessories and quantity checked against the order, photographed and sent to you before loading.

Battery-class logistics

UN38.3 reports, MSDS and packing instruction prepared per pack model, so the forwarder is not improvising at the port.

Certification

The documents, with numbers

Document	Details
ISO 9001:2015	GB/T 19001-2016 / ISO 9001:2015 quality management system. Registration no. 064-26-Q-1805-R4-01, issued 15 Oct 2026, valid to 14 Oct 2029, initial certification 13 Nov 2014. Scope: design and production of lithium battery products (limited for export).
Holder	GUANGDONG BOLTPOWER ENERGY CO., LTD. · Unified social credit code 91441900068530796F · No. 22 Xinfu Road, Lincun, Tangxia Town, Dongguan, Guangdong 523710.
UN38.3 + MSDS	Transport documents issued per pack model, required for air and sea shipment of lithium batteries.
CE / RoHS	EU declarations and test reports. Coverage depends on the SKU, the plug type and the destination market.
FCC / PSE	Available for US and Japan configurations where the SKU supports it — confirm per model before printing a claim.

Read this before you print a compliance claim. The factory certificate covers the quality system, not every product. Product-level CE, FCC and PSE documents are per SKU and per plug standard — a 230V Schuko version and a 120V version are separate files. We confirm the exact list in the quotation so your packaging claim matches the paperwork you can actually show a customs officer.

Private label

What changes on the line, and what needs a mould

No new tooling

Logo, colour, panel, language, packaging

Silkscreen, housing colour on volume, plug and voltage configuration, manual and carton artwork, accessory set, output ceiling in firmware. Typically 3–7 days for a proof.

New tooling

Enclosure shape, new port layout, new capacity

These need a mould or a new pack design. Realistic lead time is 45–75 days plus tooling cost, and MOQ is materially higher. We will tell you which side of the line your request falls on.

Order flow

Fixed spec sheet, so container two matches container one

After the first order we write the approved specification into a one-page sheet — cell, capacity, output, plug, panel, packaging, certificate list. Every repeat order is produced against that sheet, which is the cheapest way to avoid a silent component change between shipments.

Deposit 50% on confirmation, balance before shipment, inspection photos before loading. Spare parts can ride in the same container.

Request the spec sheet template

Start with a sample, not a container.

Test one unit, check the build quality and the local response, then scale. We quote FOB, CIF and DDP so you can compare landed cost before committing.
