• Cell Customization: Customize cell type, capacity, voltage, and chemistry.

    We offer cylindrical, pouch, and prismatic lithium cells in multiple specifications, including 18650, 21700, and custom formats. Each cell is optimized for your project's requirements.

  • Battery Pack Design:Modular or integrated pack solutions for your equipment.

    We design and assemble battery packs with precise BMS integration, housing design, and safety testing, ensuring compatibility and long-term stability for industrial use.

  • Performance & Function Integration:Beyond capacity – intelligent power systems.

    Add functions like smart BMS, communication interfaces (CAN/SMBus/RS485), fast-charging protocols, or IP-rated enclosures to meet professional and environmental standards.

What are the main parameters of lithium battery pack customization?

1. Define the Application Field

Each application has unique battery requirements. The cells, discharge rate, and chemistry should be tailored to the product.

  • Discharge rate: Choose the right cell for your load demand — 0.2C, 0.5C, 1C, 2C, 3C, 8C, or higher.
    Example: High-speed electric vehicles need high-current cells, while energy storage systems (ESS) typically use 0.2C cells.

  • Cell chemistry: Select NCM (higher energy density) or LFP (longer cycle life).
    Example: For compact e-bikes (48V 10Ah), NCM cells are preferred due to size constraints.

  • Cell format: Choose cylindrical , prismatic , or pouch cells.
    Example: Small batteries (eg, 36V 15Ah e-bikes) often use cylindrical or pouch cells; large projects (eg, 72V 200Ah golf carts) typically use prismatic cells for better stability.

2. Confirm Voltage and Capacity

Voltage is determined by motor power, while capacity defines runtime.
For example, a 72V 60Ah e-scooter battery offers double the range of a 72V 30Ah battery under the same motor power.

3. Define Battery Pack Dimensions

The available installation space directly affects capacity. Provide your design team with length, width, and height measurements. If your product has a nonstandard shape, share 3D drawings or photos to ensure the pack fits perfectly.

4.Specify Input and Output Interfaces

Output connectors vary across applications (EV, AGV, etc.).Confirm whether you need standard terminals , custom connectors , or dual-wire outputs before production.

5. Confirm Motor Power Requirements

The motor's rated and peak power determine the battery's continuous and peak discharge current , affecting cell selection, BMS configuration , and wire gauge .

6. Define Operating Temperature Range

Most lithium batteries charge safely between 0–45°C and discharge between –20–55°C . For low-temperature environments (eg, snowmobiles), consider integrating a heating system for stable performance.

7. Determine Charging Time

Charging speed depends on charger voltage and current. After confirming your desired charging time, the manufacturer will recommend a compatible charger (fast or standard charging).

8. Select Communication Protocol

If the battery system communicates with external devices, confirm which protocol your equipment uses — CAN , RS485 , or RS232 .

9. Provide Additional Specifications

Finally, specify other details such as:

  • Case material
  • Color
  • Discharge current
  • Mounting or sealing requirements

The more details you provide, the more accurate and efficient your custom battery solution will be

Battery Pack Customization Process

From initial inquiry to final delivery, our complete lithium-ion battery pack customization process typically takes no more than 30 days.

Step 1 (3–4 days): Requirement Definition & Quotation

We collect all technical and performance requirements from the customer, conduct a feasibility study with our engineering team, and provide an initial quotation. Once both parties agree on specifications and pricing, the project is officially approved.

Step 2 (2–4 days): Overall Design & Evaluation

Our engineers create the complete battery system design, including electrical layout, cell configuration, and structural design, followed by technical assessment and optimization.

Step 3 (1–2 days): Design Verification

We verify the design to ensure all parameters meet safety, performance, and compliance standards before moving to production.

Step 4 (10–15 days): Production & Assembly

Upon design confirmation and payment, production begins. The cells, BMS, and structural components are assembled under strict quality control.

Step 5 (2–3 days): Functional Testing & Adjustment

Each module undergoes full functional testing — including charge/discharge, communication, and safety validation — to ensure optimal performance.

Step 6 (1–2 days): Packaging & Delivery

After passing all tests, the battery packs are securely packaged and prepared for shipment.

Total lead time: Within 30 days from project approval to delivery.
