China has become the global hub for lithium battery production and advanced Battery Management Systems (BMS). With the rapid growth of electric vehicles, energy storage solutions, and smart mobility devices, BMS technology is no longer an optional add-on—it is the brain of every lithium battery pack.
For international buyers, sourcing directly from Chinese BMS manufacturers offers several advantages: access to the latest innovations, competitive pricing, and strong production capabilities. However, finding reliable manufacturers and obtaining their direct contact information can be challenging for overseas businesses.
This article provides a comprehensive list of the TOP 5 Chinese BMS manufacturers with their background details, strengths, and verified contact information. By the end, you will know not only who to contact but also why direct communication with the manufacturer matters.
Many importers or battery pack assemblers rely on distributors or trading companies to purchase BMS units. While this may seem convenient, it often leads to higher costs, limited product customization, and slower technical support. Contacting BMS manufacturers directly helps you unlock several business benefits:
Direct factory sourcing eliminates unnecessary middlemen. This means better wholesale pricing, stable supply, and transparent production costs—an important factor for companies scaling up battery pack assembly.
BMS is not a simple plug-and-play component. It requires precise calibration for voltage, current, temperature, and communication protocols. Direct contact with the manufacturer allows you to work closely with their R&D team, ensuring the system is configured for your exact application, whether it’s e-bikes, scooters, or large-scale ESS (Energy Storage Systems).
Leading Chinese BMS suppliers provide OEM/ODM services, enabling you to brand the product under your company name or request custom firmware, communication interfaces (CAN, RS485, Bluetooth), and housing designs. Such flexibility is rarely possible through third-party sellers.
In battery applications, downtime can be extremely costly. By contacting the factory directly, you ensure faster troubleshooting and real-time support, instead of waiting for intermediaries to pass messages back and forth.
Direct relationships build trust and open the door to long-term collaboration. This can include priority access to new BMS models, faster lead times, and better contract terms when your order volume increases.

The five companies listed—KURUI, TDT, DALY, JK, and AYAA Tech—represent some of the most reliable BMS manufacturers in the market, each with its own strengths and focus areas.
For businesses sourcing BMS solutions, contacting manufacturers directly is the most effective way to secure the right product, fair pricing, and dependable after-sales support. Whether you are building e-bikes, electric scooters, energy storage systems, or industrial battery packs, these manufacturers provide options to fit different project requirements.
If you are planning to source from China, consider your application needs, customization requirements, and long-term scalability before choosing the right supplier. Building strong relationships with the manufacturer will not only help with immediate needs but also position your business for future growth.
A Battery Management System (BMS) is the control unit of a lithium battery pack. It protects the battery from overcharging, over-discharging, overheating, and short circuits, while also balancing cell voltages to extend battery life and ensure safety.
Evaluate based on your application (EV, e-bike, ESS, etc.), required current/voltage range, communication protocols (CAN, RS485, Bluetooth), customization needs, and supplier’s export experience.
Yes. Many Chinese BMS manufacturers have international certifications (CE, UL, ISO) and already serve global clients. However, it is crucial to select a supplier with proven export history and reliable technical support.
Yes. Leading manufacturers such as KURUI, TDT, and DALY provide OEM/ODM services, allowing you to customize firmware, branding, and hardware design to fit your project needs.
Lead time depends on the order volume and customization level. Standard BMS units are usually available within 2–4 weeks, while custom projects may take 6–8 weeks.
