Cooperation Case
Saxophone Product Collaboration - AS18650 3.7V 2600mAh Battery
Client Background
In 2021, the renowned musical instrument manufacturer, Roland, commissioned us to develop a custom battery for their saxophone product. The customer had extremely high requirements for safety, stability, and international certifications, specifying our pre-certified 18650 3.7V 2600mAh battery (already holding UL2054, CB, and other multi-national certifications) for testing.
Deepening Collaboration
During technical discussions, we learned of Roland’s strong emphasis on safety. Based on this understanding, we proposed adding a PTC (Positive Temperature Coefficient) protection function to the existing battery design to prevent thermal runaway caused by abnormal temperature increases. Simultaneously, to support the customer’s sales in the Chinese market, we assisted them in obtaining the China Compulsory Certification (CCC).
Outcome & Value
The final delivered battery, equipped with PTC protection and holding multiple international certifications, perfectly met the customer’s requirements with its stable output and outstanding safety performance. Saxophones featuring this battery have successfully entered the market. This collaboration not only solidified our long-term partnership but also demonstrated our professional expertise in customizing battery solutions that meet high safety standards.
