Who We Are

Headquartered in Shenzhen, China, RHY specializes in the design, development and manufacture of Li-ion, Ni-MH & Ni-Cd battery packs and chargers, providing one-stop battery solutions. We have our own R&D lab and factories across Shenzhen and Dongguan with 170,000 sq. ft. production area and 300+ employees.

From power tools to vehicles, it has been a trend that restrictive cords and environmentally harmful power are being phased out, while replaced by battery-powered systems with less noise, greater mobility and fewer emissions. It was against this background that RHY was formed in 2013 to help such manufacturers accomplish product electrification.
