Origin & Purpose

Our Story & Mission

Over two decades ago, leveraging his engineering background at BYD and strategic industry networks within EVE and BAK, David Ding launched a specialized lithium battery trading venture that generated 5 million in revenue within its first three years.

Building on this early success, by 2007, recognizing that excessive costs and rigid configurations were stalling the clean energy transition, David founded Shenzhen Sunfid and launched the Holo Battery brand. His core mission was clear: to democratize clean energy by engineering high-performance, precision-customized lithium battery solutions at accessible prices.

Overcoming early challenges in global supply chains and mechanical design, the company has grown into a trusted manufacturer delivering precision-engineered battery systems across 40+ countries, driven by an unwavering commitment to engineering efficiency, affordability, and continuous innovation.
