11.1v lithium battery
What Are 11.1V Lithium Batteries?
An 11.1V lithium battery is a rechargeable battery pack composed of three 3.7V lithium-ion or lithium-polymer cells connected in series (3S configuration). This voltage platform is ideal for mid-power applications that require higher energy output than standard 3.7V or 7.4V packs, while still maintaining compact size and lightweight form. 11.1V lithium batteries are widely used in medical equipment, drones, robotics, handheld terminals, communication devices, and other portable or mobile industrial systems. For OEMs and system developers, they offer a stable and efficient solution for power-critical devices.
Higher Voltage, Enhanced Performance
Compared to lower-voltage packs, 11.1V lithium batteries provide greater energy throughput, allowing devices to run longer or operate at higher performance levels. Their flat discharge curve ensures steady voltage during use, while their low internal resistance supports fast charging and high current output. With cycle life typically exceeding 500–1000+ cycles, these batteries maintain performance across repeated charge/discharge operations. Integrated with intelligent protection systems, they offer a reliable power solution with strong thermal and electrical stability.
