TOP TECHNOLOGY

Company overview

TOP TECHNOLOGY develops and manufactures lithium batteries, with headquarters in Shunde, Foshan, Guangdong, China, where the company was established in 2019. Its work covers battery materials, cell design, manufacturing and battery-system integration, including lithium-rich manganese materials, silicon anodes and solid-state battery technology. It supplies cells and customized battery systems for industrial drones and passenger-carrying eVTOL aircraft. Other civilian applications include robots, robotic dogs, high-performance electric motorcycles, electric vehicles, energy storage systems and slim, fast-charging power banks.

Its drone battery range comprises three cell series with different energy-density and discharge ratings. The Ultra-high Energy Density series provides 400–460 Wh/kg, 3C continuous discharge and 10C pulse discharge, with support for 2C discharge at -40°C. The Ultra-high Power series provides 310–330 Wh/kg, 10C continuous discharge and 20C pulse discharge. Its additional ratings include 4C discharge at -40°C and, separately, 4C discharge at 90% state of charge. The Ultra-high Energy Density and High Power series provides 360 Wh/kg, 5C continuous discharge and 10C pulse discharge. These are cell specifications; the cold-temperature and state-of-charge ratings apply under their respective stated conditions.

The drone battery solutions address applications such as long-distance power-grid inspection, forestry surveys, maritime patrols around islands, small-item transport in mountainous areas, large-area land surveying, forest-fire reconnaissance and supply drops. Battery development for passenger-carrying eVTOL aircraft focuses on low weight, endurance and high-rate discharge. TOP TECHNOLOGY also offers customization for projects with different requirements, progressing from application assessment and cell or battery-system design through prototype preparation, performance validation and production delivery.
