When sourcing lithium battery packs, businesses often come across the terms OEM and ODM. Both models allow companies to work with a battery manufacturer without necessarily manufacturing the battery themselves, but the level of customization and product development is different.

For EV batteries, e-bike batteries, drone batteries, solar batteries, ESS systems and industrial battery packs, understanding the difference between OEM and ODM can help you choose the right manufacturing model.

What Is OEM Battery Manufacturing?

OEM stands for Original Equipment Manufacturer.

In an OEM arrangement, the customer generally provides the product specifications, design requirements or engineering drawings, and the battery manufacturer produces the battery according to those requirements.

Example

A company needs a:

48V 30Ah NMC Battery Pack

The customer provides:

• Voltage
• Capacity
• Cell type
• Battery dimensions
• BMS requirements
• Connector
• Enclosure design
• Mounting arrangement
• Wiring requirements

The manufacturer then produces the battery according to those specifications.

OEM Battery Manufacturing Can Include

• Custom lithium battery packs
• EV battery packs
• E-bike batteries
• Drone batteries
• Solar batteries
• ESS batteries
• UPS batteries
• Industrial battery packs
• Custom BMS integration
• Custom battery enclosures

What Is ODM Battery Manufacturing?

ODM stands for Original Design Manufacturer.

In an ODM arrangement, the manufacturer provides more of the product design and engineering development.

The customer may provide only the basic requirements, such as:

“We need a lightweight 72V battery for our electric motorcycle.”

The manufacturer can then assist with:

• Cell selection
• Series/parallel configuration
• Capacity calculation
• BMS selection
• Electrical design
• Mechanical design
• Enclosure design
• Connector selection
• Battery assembly
• Prototype development

The finished product can then be supplied under the customer’s brand, subject to the commercial and intellectual-property agreement.

OEM vs ODM Battery Manufacturing

Simple Example

OEM

You already have a complete battery design.

Your Design → Manufacturer → Production

For example:

13S6P NMC Battery
48V class
27Ah
DMEGC 21700 Cells
60A BMS
Custom enclosure

You provide the specifications and the manufacturer builds it.

ODM

You have a product requirement but don’t have the complete battery design.

Your Requirement → Engineering → Prototype → Testing → Production

For example:

“We need a battery for our electric scooter with approximately 60 km range.”

The manufacturer can help develop the battery specification based on the vehicle’s power requirements, available space, desired range and operating conditions.

OEM Battery Manufacturing Process

A typical OEM project may follow:

Customer Specification
↓
Technical Review
↓
Quotation
↓
Prototype / Sample
↓
Approval
↓
Production
↓
Testing
↓
Delivery

OEM is particularly useful when the customer already has a validated battery design.

ODM Battery Development Process

ODM projects generally involve more engineering:

Product Requirement
↓
Application Analysis
↓
Cell Selection
↓
Electrical Design
↓
BMS Selection
↓
Mechanical Design
↓
Prototype
↓
Testing & Validation
↓
Design Approval
↓
Production

OEM Battery Manufacturing Applications

OEM manufacturing can be suitable for companies that already have a defined product.

🚲 E-Bikes

Custom battery packs according to an existing battery compartment.

🛵 Electric Scooters

Battery packs designed according to an established vehicle specification.

🚁 Drones

Production of batteries according to an existing drone battery design.

☀️ Solar

Standardized battery packs for solar and backup-power products.

🏭 Industrial Equipment

Replacement or production battery packs according to existing specifications.

ODM Battery Manufacturing Applications

ODM is particularly useful for companies developing a new battery-powered product.

Examples include:

• New electric scooter
• New electric motorcycle
• Agriculture drone
• Mapping drone
• Robotics platform
• Portable power station
• Industrial equipment
• Custom ESS
• Specialized medical equipment

Private Label Battery Manufacturing

OEM and ODM can also be combined with private-label battery manufacturing.

For example:

Customer Brand
↓
Custom Battery Design
↓
Battery Manufacturing
↓
Customer Branding
↓
Finished Product

The exact branding, intellectual-property ownership and documentation arrangements should be agreed upon before production.

OEM vs ODM: Which One Should You Choose?

Choose OEM if:

• You already have a battery design.
• You know the required cell configuration.
• You have specified the BMS.
• You have battery drawings.
• You have an existing enclosure.
• You need repeat production.

Choose ODM if:

• You have an idea but no complete battery design.
• You need help selecting cells.
• You need BMS recommendations.
• You need enclosure development.
• You need a prototype.
• You are developing a new EV, drone or industrial product.

Why Work With an OEM/ODM Battery Manufacturer?

Working with an experienced battery manufacturer can help businesses avoid having to establish their own complete battery assembly infrastructure.

Depending on the project, the manufacturer can support:

Design → Components → Assembly → Testing → Production

This can be especially valuable for startups and companies launching new battery-powered products.

Frequently Asked Questions

Is OEM better than ODM?

Neither is automatically better. OEM is generally better when you already have a finalized design, while ODM is useful when you need more design and engineering support.

Can a battery manufacturer provide both OEM and ODM?

Yes. A manufacturer can offer specification-based OEM production as well as custom product development, depending on its capabilities.

Can I sell an ODM battery under my own brand?

This can be possible under a private-label or ODM agreement. Branding, design ownership and intellectual-property rights should be clearly defined in the contract.

Is ODM more expensive than OEM?

ODM can involve additional engineering, prototype and development costs. The total cost depends on the complexity of the project.

Can Lion Battery manufacture custom EV batteries?

Yes, Lion Battery can develop and manufacture custom lithium battery packs for applications such as EVs, e-bikes, scooters, drones, solar, ESS and industrial equipment.

Conclusion

The basic difference is simple:

OEM = You provide the design, manufacturer builds it.

ODM = You provide the requirement, manufacturer helps design and build it.

For an established battery product, OEM manufacturing can be the straightforward choice. For a new EV, drone, ESS or industrial product that requires battery engineering, ODM manufacturing can provide greater development support.
