11.1v lithium battery
What Are 11.1V Lithium Batteries?
11.1V lithium batteries are three-cell lithium-ion battery packs (3S configuration) that deliver a nominal voltage of 11.1V by connecting three 3.7V cells in series. This voltage level is ideal for medium-to-high-power applications that require compact design, consistent output, and lightweight energy storage. As pre-configured, off-the-shelf solutions, 11.1V lithium battery packs come with built-in protection circuits, reducing engineering complexity and enabling faster integration into end-products. Large Power’s 11.1V battery lineup provides reliable energy for a wide range of devices, from robotics to portable medical equipment, without the long lead times of custom-designed systems.
