China makes more lithium battery packs than any other country. Most of the world’s phone, laptop, e-bike, forklift and home energy storage batteries are assembled there, by thousands of companies ranging from listed groups with more than 10,000 employees to small workshops.
This list covers 10 established lithium battery pack manufacturers in China in 2026. It starts with seven manufacturers that build custom battery packs for OEMs, followed by three large, publicly listed groups. For each company we give the location, main products and official website, so you can check them yourself.
Disclosure: This article is published by Holo Battery, which is also on this list.
How We Chose These Companies
- Pack manufacturers, not cell makers: Every company on this list builds finished battery packs with a BMS and enclosure. Some also make their own cells. For the largest cell makers, such as CATL and BYD, see our list of the 15 largest lithium-ion battery manufacturers.
- Own factories in China: Each company runs its own manufacturing in China. Trading companies without a factory are not included.
- Export experience: Each company sells to overseas customers and lists international certifications such as UN 38.3, IEC 62133 or UL.
- Order of the list: The list is written for companies that need a custom battery pack. Manufacturers that accept custom projects from OEMs of any size come first. The three large listed groups come last, because they mainly serve very large customers.
- Public information: Revenue figures for listed companies come from their 2025 annual results. Other figures, such as factory size, come from each company’s own website and are labeled as company claims.

Cell Maker, Pack Manufacturer or Trading Company?
When you search for a battery supplier in China, you will find three kinds of companies. It helps to know which one you are talking to.
- Cell makers: Companies such as CATL, EVE and BYD make the cells themselves. They sell mainly to carmakers and large energy storage companies, and rarely build custom battery packs for small customers.
- Battery pack manufacturers: They buy cells, often from the large cell makers, and design the battery pack around them: cell configuration, BMS, wiring, enclosure, testing and certification. Most custom battery projects are built by this kind of company.
- Trading companies: They sell battery packs made by other factories. Some are reliable, but they cannot change a design themselves, and quality depends on a factory you never see.
Many Chinese suppliers call themselves a factory online. Ask for a video call from the production line, or visit in person, before you place a large order.
How to Check a Chinese Battery Pack Supplier
- Business license: Ask for a copy and check that the company name and scope include battery manufacturing, not only trading.
- Certificates: Ask for test reports in your company’s name or for the exact battery model, not general certificates. At a minimum, a lithium battery pack must pass UN 38.3 to be shipped. Depending on the product, you may also need IEC 62133, IEC 62619, UL 2054, UL 2271 or UL 1973. See UN 38.3 vs IEC 62133 vs IEC 62619.
- Cell source: Ask which cell brand and model the battery pack uses, and whether the cells are Grade A. Ask to be told in writing if the cell source changes.
- BMS design: Ask whether the BMS is designed in-house or bought in, and whether it supports the communication your device needs, such as CAN, RS485 or Bluetooth.
- Samples and testing: Order samples first and test them for capacity, cycle life, temperature and protection functions before mass production.
- Lead time and MOQ: Ask for separate sample and production lead times, and for the minimum order quantity with and without custom tooling.
- Shipping and total cost: Lithium batteries ship as dangerous goods. Compare DDP quotes, which include freight, customs clearance and duties, rather than ex-works prices.

FAQ
Who is the largest lithium battery pack manufacturer in China?
For consumer electronics, Desay Battery and Sunwoda are the largest battery pack assemblers; both supply global phone and laptop brands. For EV batteries, CATL and BYD are the largest, but they make cells and battery systems mainly for carmakers rather than custom battery packs for other companies.
Where are most battery pack manufacturers in China located?
Most are in Guangdong province, especially Shenzhen, Dongguan and Huizhou, close to the electronics supply chain. There are also large clusters in Jiangsu, Zhejiang, Fujian and Anhui.
Can I order a small quantity of custom battery packs from China?
Yes, from many specialist manufacturers. Large listed companies usually require high volumes, but smaller custom battery pack makers often accept sample orders and first batches of 100 units or fewer, especially when no new tooling is needed.
How long does it take to get custom battery packs from China?
Samples typically take 2 to 5 weeks, depending on whether the cells are in stock and whether new tooling is needed. Mass production usually takes 4 to 7 weeks, plus shipping. Sea freight to the United States or Europe adds about 4 to 6 weeks; air freight adds about 1 week.
What certifications should a battery pack from China have?
UN 38.3 is required to ship any lithium battery. IEC 62133 is common for portable devices, IEC 62619 for industrial and energy storage batteries, and UL standards such as UL 2054, UL 2271 or UL 1973 are often required for the U.S. market.
