Custom Lithium Battery Packs: Your Complete Guide to Sourcing from Li-Yue Battery

The Challenge of Finding the Right Battery Partner

You have a product to power—whether it’s a golf cart, energy storage system, forklift, RV, or marine equipment. You know lithium is the future, but:

  • Standard batteries don’t fit your compartment?
  • You need a specific voltage or capacity?
  • You want your own brand on the product?
  • You’re tired of quality inconsistencies from unreliable suppliers?

If any of these sound familiar, you’re in the right place.

At Li-Yue Battery, we’ve been manufacturing lithium batteries since 2001. We offer three flexible ways to work with us, depending on your business model and technical capabilities.


Three Ways to Partner with Li-Yue Battery

Option 1: Purchase Our LiFePO4 Soft Pack Cells (Build It Yourself)

If you have your own battery assembly capabilities, you can simply purchase our high-quality LiFePO4 pouch cells and build packs in-house.

Batches of pouch lithium batteries are coming off the production line

What we offer:

  • Capacity range: 5Ah to 100Ah per cell
  • อายุการใช้งานของวงจร: 3,000–10,000+ cycles (Grade A materials guaranteed)
  • Custom dimensions available: Tell us your compartment size
  • BMS not included (but we can recommend compatible options)

Best for: Companies with existing pack assembly lines who want reliable, consistent cells at factory-direct prices.

Option 2: We Assemble Custom Battery Packs for You (OEM/ODM)

Don’t want the hassle of assembly? We handle everything—from cell selection to BMS integration to final housing.

Lithium battery production line

What we offer:

  • Custom voltage/capacity: Any series/parallel configuration
  • BMS integration: With CAN/RS485 communication if needed
  • Custom housing: Dimensions, materials, connectors—you specify
  • Wiring and labeling: Ready to install in your product

Best for: Companies who want plug-and-play battery solutions without investing in assembly equipment.

Typical applications:

  • Golf cart battery packs (36V, 48V, 72V)
  • Energy storage systems (rack-mounted, wall-mounted)
  • Forklift and floor machine batteries
  • RV and marine battery packs
  • Custom industrial applications

Option 3: Private Label Our Standard Battery Packs (Your Brand, Our Products)

Already designed a battery pack that works for many customers? We have standard designs that you can rebrand and sell as your own.

What we offer:

  • Proven designs: Already tested and field-validated
  • Your logo, your packaging: We apply your branding
  • Quick turnaround: No R&D time needed
  • Volume pricing: Better margins for you

Best for: Distributors and brands who want to enter the lithium market quickly with minimal upfront investment.

Standard designs available:

Why Work with Li-Yue Battery?

24+ Years of Manufacturing Excellence

Since 2001, we’ve focused on one thing: making reliable lithium batteries. Not chasing headlines, not hyping unproven technology—just consistent, quality manufacturing.

2GWh Annual Capacity

Our 260,000-square-meter super factory houses three automated production lines, capable of producing millions of cells annually. We have the scale to serve large orders while maintaining quality.

Full Control: From Cell to Pack

Unlike many assemblers who buy cells on the open market, we manufacture our own cells. This means:

  • Traceability: Every cell’s history is recorded
  • Consistency: Matched cells within 2% capacity
  • Quality: Grade A materials only, no B-stock
