FAQS ABOUT OUR LITHIUM-ION BATTERY SUPPLY CHAIN
Lithium-ion batteries have an excellent and improving energy density to cost ratio. Fueled by production scale from electric vehicles, laptops, and other devices, lithium-ion is on track to be the world's premier form of clean energy storage. Modern lithium-ion batteries are safe, inexpensive, and offer performance benefits over all other battery types.
We are a lithium-ion battery supplier that has helped power products for clients including globally recognized brands and leading universities and laboratories. Our lithium-ion batteries have powered submarines, spacecraft, and everything in-between. Our core competency is in the large-scale manufacturing of small to medium format lithium-ion battery packs. Some industries we supply include home energy storage, electric vehicles, medicine, military, computing, power tools, robotics, sensors, and more. While we are primarily a large-scale B2B company, we also dedicate support for pioneering startups.
Our main factory in Dongguan, China provides battery pack assembly and testing.
Our battery pack manufacturing centers in Xiamen and Shenzen provide additional services and the production of lithium-ion battery packs and cells. With over 50 years of combined experience in lithium-ion battery technology, no project is too big for us to handle.
All of our facilities utilize the ISO:9001 process quality management system approach for all executed projects. This ensures we are able to identify, measure, control, and improve continually on our core processes leading to excellent business performance and customer satisfaction.
All lithium-ion cells and component parts are purchased only from authorized manufacturers and distributors with supporting proof-of-purchase documentation where it may apply.
Voltaplex has a zero-tolerance policy for counterfeit goods and parts.
The typical manufacturing process for lithium-ion battery packs is:
- Issuance of the specification sheet
- Component consolidation
- Assembly line scheduling
- Cell testing, cell matching, material matching
- PCB testing
- Glue and/or bracketing
- Spot welding nickel or other tabbing
- Spot welding PCB/PCM/BMS
- Application of insulation barley paper
- Welding wires, cables, connectors
- Application of temperature tape
- Application of insulation foam, insulation paper, and PVC heat shrink wrap or other casing
- Cycle age testing, visual inspection, photography, and other tests
- Packaging and issuance to the freight forwarder
Original Equipment Manufacturer (OEM):
We manufacture battery packs based on your product designs and specifications.
Original Design Manufacturer (ODM):
We create your battery pack design and specifications based on a product idea brief you send us.
If you desire to prototype or assemble battery packs in-house, we can supply cutting-edge lithium-ion cells from leading manufacturers like Panasonic, Sanyo, LG, Samsung, Sony, BAK, Lishen, and others. We have a wide range of cells to choose from, including all sizes of cylindrical, polymer, prismatic, coin, flexible, and other cell types to fit your application. All of our cells are guaranteed 100% authentic and are backed by free replacement or refund warranty to meet performance specifications.
Our facilities are equipped to test lithium-ion cells and battery packs for all major safety and environmental conditions.
Our most common tests for UN38.3 and other certificates include:
- Impact (crush, puncture, drop-mass, etc.)
- Altitude simulation & pressure
- Thermal abuse
- Vibration
- Shock
- External & internal short circuit
- Overcharge
- Forced discharge
- Cycle life (up to 80V/module)
- Other testing may be available upon request.
Other testing may be available upon request.
All of our production facilities are ISO:9001 certified and certification(s) can be provided upon request.
We can provide MSDS (Material Safety Data Sheet) on request.
We have obtained worldwide certifications including BIS, UL, CE, ROHS, UN/BOT 38.3, and others for custom built battery packs for our clients.
Certifications are generally geographically dependent. We can produce most mandatory or voluntary certifications for battery packs or cells on your behalf. We can also provide the necessary sample products, testing reports, and supplementary files for you to file for certification yourself.

We offer loose cells and components like tabbing so companies wishing to assemble packs in-house can do so as effectively as possible. Companies may wish to do this for several different reasons. The battery pack arrangement may be heavily customized, or a company might be rapidly prototyping.
Choosing to outsource the manufacturing of lithium-ion battery packs has several distinct advantages - with the foremost being cost. Producing the packs in Asia with a specialized battery pack manufacturer like Voltaplex can save money in a few ways. The primary cost when producing packs are the cells. Our factory purchases cells in bulk via established relationships for multiple customers, passing this cost-savings down to you. Furthermore, labor and material costs are reduced. Finally, the important step of issuing safety certifications for each pack requires expensive machinery that only specialized lithium-ion manufacturers can invest in.
There are some other advantages to outsourcing your packs to Voltaplex. Engineering a safe lithium-ion pack is difficult, and requires technical knowledge and an in-house team might not possess. Voltaplex sits in the heart of the lithium-ion battery supply chain and our factory is near other supporting industries, like cable, PCB, and charger factories - meaning additional products and services are less expensive to provide.
There is no MOQ for loose cells, however we suggest an MOQ of 50 cells for cost-effective shipping.
There is also no MOQ on custom battery packs, however, we require that low quantity orders are business or industrial samples.
