An 11.1V / 12V battery pack generally refers to a rechargeable pack assembled from multiple lithium cells to provide a nominal output close to 12 volts. A common configuration is a 3-series (3S) pack of 3.7V nominal cells, resulting in an 11.1V nominal pack with a fully charged voltage around 12.6V and a cut-off voltage around 9V, depending on the protection settings.
Compared with lower-voltage packs, 11.1V / 12V battery packs reduce the current required for a given power level, which helps to minimize cable losses, improve efficiency and support higher-power loads in a compact form factor.
11.1V / 12V battery packs are widely used in portable test and measurement instruments, professional cameras and video equipment, two-way radios, communication terminals, medical devices, mobile robots, AGVs, small electric tools and security or alarm systems.
They are also common in compact UPS and backup power modules for routers, controllers and other low-voltage electronics that expect a “12V DC” input.
11.1V / 12V battery packs can be customized in terms of capacity, discharge rate, cell type, housing structure and interface to match specific project requirements. By optimizing both the electrical design and mechanical layout, these packs can provide an efficient, space-saving and safe power solution for a wide variety of industrial, commercial and consumer applications that rely on 12V-class DC power sources.
