Quality Assurance Process

Material Selection

We begin by sourcing RoHS and REACH compliant materials, subjecting them to our Incoming Quality Control (IQC) processes to ensure the highest standards. By implementing Supplier Relationship Management (SRM), we guarantee consistent material quality and optimal cost-effectiveness.

Quality Control

Our well-rounded quality control measures cover PCB, cell balance, welding, assembly, and testing. All processes are meticulously documented, traceable, and monitored for consistency and reliability.

Continuous Improvement

We maintain a proactive approach to quality enhancement through regular evaluation, corrective actions, and product lifecycle management. Our commitment extends to resolving any quality issues promptly and continuously improving our offerings.

Testing and Certifications

Our products undergo a series of rigorous tests, including AOI Testing, Battery Capacity Detection, Aging Test, and more. All tests are conducted using automatic equipment. These tests are crucial in ensuring the quality and reliability of our products.

Prior to delivery, every product undergoes compatibility trials where it is installed on its host devices. This step is essential in verifying seamless match and optimal performance, ensuring that our products meet the highest standards of compatibility and functionality.

We collaborate with accredited laboratories such as UL, TUV, Intertek, and SGS to certify and further enhance our products. These partnerships enable us to validate our products against industry standards and regulations, ensuring that our offerings consistently meet or exceed quality benchmarks.

Warranty and Support

To further instill confidence in our products, we offer a comprehensive one-year warranty. In the unlikely event of defects caused by non-artificial reasons, we provide free replacements or repairs within the warranty period. Our commitment to quality is not just limited to products; we offer lifetime technical support to ensure your continued satisfaction and peace of mind!
