In the global energy transition, lithium batteries have become the core power source for electrification. Compared to traditional lead-acid batteries, lithium batteries offer higher energy density, longer lifespan, fast charging capabilities, and lower maintenance costs. They are widely used in golf carts, forklifts, cleaning vehicles, floor scrubbers, aerial work platforms, marine applications, electric agricultural and construction machinery, as well as energy storage systems.

However, every piece of equipment operates under unique conditions and usage scenarios. Off-the-shelf batteries often cannot meet these specific requirements. To fully leverage the advantages of lithium batteries, partnering with a supplier that has extensive industrial experience and strong customization capabilities is crucial.

Since 2011, the BSLBATT team has been dedicated to providing reliable lithium battery solutions for OEMs and equipment manufacturers worldwide. We offer not only battery products but also full-process support—from requirements analysis to mass production—helping customers successfully electrify their equipment.

Custom Lithium Battery Development Process

Listening & Requirements Analysis

We engage in in-depth discussions with clients to understand the equipment’s specific use cases, including:

• Power requirements and energy consumption profiles

• Work cycles and operating hours

• Available charging time and environmental conditions

• Electrical interfaces and safety standards

These insights allow us to tailor the battery solution to each client’s needs.

System Design & Technical Proposal

Once requirements are clear, our engineering team develops a complete battery system plan:

• Cell selection and module configuration

• Customized BMS (Battery Management System) functions

• Enclosure design and structural layout

• Electrical interfaces and communication protocols (e.g., CAN bus)

BSLBATT can also provide a full electrification solution, including inverters, chargers, and monitoring platforms.

Prototype Development & Verification
After the technical plan is approved, we produce detailed 2D/3D technical drawings and circuit designs, then develop prototype samples. Each prototype undergoes multiple tests:

• Laboratory performance testing

• Safety standard verification (e.g., UN38.3, CE, UL)

• Compatibility testing with the full equipment

On-site Installation & Testing

We assist clients in installing the batteries and conducting field tests:

• Verify stable connections with equipment and chargers

• Simulate performance under different loads and operating conditions

• Optimize energy efficiency and runtime

This step ensures that the battery performs reliably in real-world conditions before mass production.

Mass Production & Delivery

Once prototypes pass all tests, the project enters mass production. With our factory-scale capacity and stable supply chain, we ensure:

• Consistent delivery schedules

• Strict quality control

• Fully traceable production systems

Training & After-sales Support

BSLBATT provides full lifecycle support:

• Installation, usage, and maintenance training for clients and distributors

• Remote monitoring and data diagnostics

• 24/7 global after-sales service
