International Standards Compliance

All incoming materials, processing, production and inspection procedures are enforced strictly in accordance with ISO9001:2015 quality management system.

All our facilities and processes are certified by ISO9001, BSCI and SQP.

All our products are designed to meet international standards such as CE, UL, FCC, PSE, KC, RoHS, UN38.3… We can also modify the existing products to meet these standards on request.


How It Works

We Prevent It: start with materials

All incoming materials are RoHS and REACH compliant. We use all the best materials for battery and charger production. Under the ISO9001 management system, we strictly select suppliers, regularly evaluate suppliers and timely replace unqualified suppliers.

We Control It: strict quality control

Through strict quality control in all processes of cell matching, welding, assembly and testing, every battery we deliver is 100% high-quality, safe and reliable. Highly automated production lines ensure the consistency and stability of product quality.

We Correct It: resolve on site

We have a well-rounded evaluation and accountability mechanism. Our production department meets every night to summarize the quality abnormalities in the production of the day, and solve them on site to avoid any recurrence in future work.

We Improve It: Product Lifecycle Management

We keep evaluating and managing our products to further improve their performance, minimize failure rates and maintain a consistently high level of product quality. In case of product failures occurred in hands of customers, we actively respond, compensate for the losses and improve them before the next production.

100% Inspected from Design to Manufacture

Our batteries and chargers are engineered to meet ISO, IEC, UN38.3 and other standards specified by customers. We cooperate with accredited laboratories like UL, TUV, Intertek, SGS, etc. to certify and improve our products.

Prior to assembly, all materials are checked by IQC inspectors to make sure they are certified, qualified and meet our requirements. Highly automated equipment and well-trained workers ensure superior and consistent quality.

We install battery on original devices for trial run to test its compatibility. Each product has to pass aging test and OQC inspection. Products can be delivered only if they have passed all inspections.

One Year Warranty

If these are not enough to give you full confidence in the quality of our products, please remember that we provide a one-year warranty, free replacement or repair will be provided for defects caused by non-artificial reasons within one year. Our technical support is for life!
