OEM Lithium Battery Manufacturer — Production to Your Design
Zenilove is a professional OEM lithium battery manufacturer based in Shenzhen, China. We produce custom lithium battery packs strictly according to your specifications, drawings, and brand requirements. From cell selection and BMS integration to final assembly and packaging, our OEM battery services turn your design into a production-ready product — with consistent quality, scalable supply, and full confidentiality.
What Is OEM Lithium Battery Manufacturing?
OEM (Original Equipment Manufacturer) means you provide the design, and we manufacture it. Your engineering team owns the specifications, intellectual property, and final product identity. As your OEM battery supplier, our role is to deliver consistent, high-quality production that matches your design intent — every batch, every shipment.
Our OEM lithium battery services are ideal for brands and companies that already have:
- A finalized battery design or detailed technical specifications
- Defined performance requirements (voltage, capacity, dimensions, BMS protocol)
- Existing branding and packaging standards for private label production
- A need for a stable, scalable OEM battery factory partner

Frequently Asked Questions About OEM Lithium Battery
What is the difference between OEM and ODM lithium battery services?
OEM means you provide the design and we manufacture it under your brand. ODM means we provide the design based on your requirements, and produce it under your brand. OEM gives you full IP ownership and design control; ODM is faster and requires less internal engineering work. Zenilove offers both — choose our OEM lithium battery services if your team already has finalized specifications, or ODM if you need design support.
Do I need a complete design before starting an OEM battery project?
Yes. Working with an OEM battery manufacturer works best when you provide finalized specifications, drawings, and performance requirements. If your design is incomplete or you need engineering input, our ODM or JDM services may be a better fit.
What is your minimum order quantity (MOQ) for OEM lithium battery production?
MOQ depends on your battery format, specifications, and customization complexity. As a flexible OEM battery factory, we work with both pilot-scale projects and large-volume production. Contact our team with your requirements for a project-specific quotation.
How is my OEM battery design protected?
We sign NDAs (Non-Disclosure Agreements) before receiving any sensitive design files. Your specifications, drawings, and brand identity remain confidential and are not shared, reused, or applied to any other client's project.
Can you produce private label lithium batteries under our brand?
Yes. We support private label lithium battery production with custom labels, logo printing, and packaging according to your brand guidelines. Final products ship as your branded product, ready for distribution.
What is the typical lead time for OEM lithium battery production?
Lead time depends on your project scope, certification requirements, and order volume. After reviewing your specifications, our OEM lithium battery manufacturer team provides a clear production schedule covering sample, mass production, and shipment milestones.
Which certifications do you support for OEM batteries?
We support UN38.3, MSDS, sea transport, and air transport certifications for international shipping of OEM lithium batteries. Additional application-specific certifications can be discussed based on your target market.
