Ryder Electronics established in Shenzhen on July 18, 2005, mainly in the business of battery packs. In 2009 the company passed ISO9001 and improved the product quality standard to fulfill the high-end requirements from our customers.

In 2012, Ryder Electronics moved to a new facility and expend the production capacity, the Productivity improved nearly 10 times than before.

In 2013, Ryder Electronics imported ERP (SAP) system to supervise order execution process.

In 2017, Ryder Electronics expanded the SMT, imported high-speed patch machine from Germany.

Until now the factory grows into a modern enterprise which integrated injection molding, PCB designing, SMT and battery pack assembling services.

In 2018 the company passed ISO14001certification, introduced automated battery production line to further improve the production quality and capacity.
