About Joolee Battery (Shenzhen) Co., Ltd. - Batteries & Chargers Supplier in China

Joolee Battery (Shenzhen) Co., Ltd. is based in Shenzhen, Guangdong Province, China. The company lists five distinct lithium‑ion battery pack models in its catalogue. Products include a 3.7 V lithium‑ion polymer pack, and 7.4 V, 11.1 V, 14.8 V and 18.5 V lithium‑ion packs, all classified under the Batteries & Chargers category. The catalogue groups these items under HS Chapter 85, which covers electric accumulators and related parts. The supplier’s active product count of five reflects a focused range of voltage configurations.

All five items are lithium‑ion battery packs intended for integration in portable electronics, power‑tool modules and low‑voltage electric equipment. The voltage tiers correspond to typical series‑cell configurations (single‑cell 3.7 V, 2‑cell 7.4 V, 3‑cell 11.1 V, 4‑cell 14.8 V, 5‑cell 18.5 V). The catalogue does not provide capacity or certification details; buyers should verify compliance with UN 38.3 transport test, IEC 62133 safety standard and any regional CE, UL or RoHS requirements.

Product Range and Specialties of Joolee Battery (Shenzhen) Co., Ltd.

The catalogue offers five lithium‑ion battery packs distinguished by nominal voltage: 3.7 V polymer, 7.4 V, 11.1 V, 14.8 V and 18.5 V. In the broader market, such packs are commonly supplied in capacities ranging from 1 Ah to 5 Ah, with energy densities between 150 Wh/kg and 250 Wh/kg. Typical specifications include built‑in protection circuits for over‑charge, over‑discharge and short‑circuit, and a recommended operating temperature of - 20 °C to 60 °C. Buyers often receive the packs in anti‑static cardboard boxes, stacked on wooden pallets suitable for 20‑ft or 40‑ft container loading (approximately 2‑3 ton per container).

Trade and Export Information - Joolee Battery (Shenzhen) Co., Ltd.

China is a major exporter of lithium‑ion battery packs, with HS code 8507.60 covering rechargeable lithium‑ion accumulators. Export shipments frequently target North America, the European Union, and Southeast Asian OEMs that assemble consumer electronics, power tools and small electric vehicles. Importers usually request compliance with UN 38.3 for safe transport, IEC 62133 for safety, and regional certifications such as CE (EU), UL (US) or RoHS for hazardous substance limits. Standard logistics involve FOB Shenzhen or Shanghai, with CIF options to major ports; containers are loaded with pallets and secured with stretch film to meet ISO 1496‑2 specifications for hazardous goods handling.

Regulatory scrutiny has increased for lithium‑ion packs due to fire risk, so customs authorities often inspect documentation for safety test reports, material safety data sheets (MSDS) and third‑party certification. Exporters from China typically provide a commercial invoice, packing list, certificate of origin and test certificates. Buyers should anticipate lead times of 4‑6 weeks for production and 2‑3 weeks for sea freight, depending on volume and destination.

Sourcing from Joolee Battery (Shenzhen) Co., Ltd. - Buyer Guidance

When sourcing from Joolee Battery, request a detailed data sheet that lists nominal capacity (mAh), continuous discharge current, cycle life and protection circuit details for each voltage model. Ask for UN 38.3 test reports and IEC 62133 conformity certificates to confirm safety compliance; these documents are standard for lithium‑ion packs and are often required by freight forwarders and import regulators.

Confirm the packaging format (e.g., anti‑static boxes, pallet dimensions) and verify that the packs are sealed to meet IEC 62368‑1 for electronic equipment safety. Buyers should also inquire about minimum order quantities, which in the Chinese battery market typically start at 500 units per voltage variant, and request a sample batch for performance testing before confirming larger orders.

What voltage options does Joolee Battery offer?

The supplier lists five lithium‑ion pack voltages: 3.7 V polymer, 7.4 V, 11.1 V, 14.8 V and 18.5 V.

Which HS code applies to these battery packs?

Lithium‑ion rechargeable packs fall under HS Chapter 85, commonly recorded as 8507.60 for lithium‑ion accumulators.

What safety standards should I verify for these packs?

Buyers should request UN 38.3 transport test results and IEC 62133 safety certification, as well as any regional CE, UL or RoHS compliance documents.

Are there typical capacity ranges for the listed voltages?

In the industry, 3.7 V cells are offered from 1 Ah to 5 Ah, and higher‑voltage series packs (7.4 V to 18.5 V) usually combine cells to achieve similar or higher total capacities, often 2 Ah to 10 Ah depending on application.

What packaging and shipping format is common for these packs?

Suppliers typically pack the packs in anti‑static cardboard boxes, palletized on wooden pallets that fit standard 20‑ft or 40‑ft containers; stretch‑film wrapping is used to secure the load.

What documentation is normally required before import?

Importers usually request a commercial invoice, packing list, certificate of origin, UN 38.3 test report, IEC 62133 certificate and, where applicable, CE or UL certification.

What are typical lead times for orders from China?

Lead times for lithium‑ion battery packs from Chinese manufacturers are generally 4‑6 weeks for production, plus 2‑3 weeks for sea freight to major ports.

Is there a minimum order quantity for these battery packs?

In the Chinese market, minimum order quantities often start around 500 units per voltage model, but exact MOQ should be confirmed with the supplier for each pack type.
