25.9V 35000mAh high‑capacity drone battery
1 Product Introduction
This 25.9V 35Ah 7S lithium battery pack offers high power capability and dependable performance for industrial and commercial applications. With up to 5C continuous discharge, it can support high load equipment that requires instant power and stable operation. The built in BMS provides essential protection for overcharge, over discharge, overcurrent and short circuit, while helping to balance cell voltage and extend battery cycle life.
The battery operates at a nominal voltage of 25.9V, with a full charge voltage of 29.8V and discharge cut off at 17.5V. It supports standard 1C charge and discharge, making it compatible with many common charging systems. The high capacity 35Ah rating provides longer runtime for each charge, while the robust housing and compact dimensions make installation easier in industrial equipment, robotics, AGVs, mobile power units and energy storage systems.
We supply this battery pack directly from the factory, ensuring consistent quality, competitive pricing and reliable delivery. Each battery is fully inspected and tested before leaving the production line. Whether you need a single unit for testing or bulk supply for your project, we can support different order quantities and provide technical guidance to help you integrate the battery safely and effectively.
