Your Custom Lithium Battery Solution
Cleonflow designs, builds, and supports custom lithium batteries. We partner with you from start to finish to create the ideal battery for your specific application.
Our Services
Standard batteries often don't meet special needs. Cleonflow creates custom lithium battery packs designed just for your product or project. We focus on the right performance, size, safety, and long life for your application. We work closely with you as your trusted partner through every step to help you succeed in your market.
Custom Battery Design & Engineering
Our expert engineers design a custom lithium battery specifically for you. This includes choosing the correct cells, designing the Battery Management System (BMS) for safety and control, creating the battery case, and managing heat effectively.
Agile Prototyping & Scalable Manufacturing
We accelerate your product development through rapid, iterative prototyping and rigorous validation. Our manufacturing capabilities are flexible, supporting everything from initial pilot runs to high-volume production, all under stringent quality control (ISO-compliant processes) to ensure consistency and reliability.
Battery Management System Development & Integration
We develop and integrate custom Battery Management Systems (BMS) featuring sophisticated algorithms. These systems provide precise cell balancing, accurate state-of-charge (SoC) and state-of-health (SoH) monitoring, comprehensive fault protection, and tailored communication protocols (e.g., CAN, SMBus, I2C) for seamless integration with your host device.
Lifecycle Partnership & Technical Integration Support
Our commitment extends beyond delivery. We provide expert technical support for seamless system integration, offer comprehensive warranty services, and advise on end-of-life management and next-generation battery solutions, fostering a long-term partnership focused on your evolving power needs and market success.


Customization Process
We use a clear, 7-step process for every custom battery project. This simple process helps us work closely with you and maintain open communication from the beginning to the very end, ensuring your project's success.
