Application:
Power Tools
The 18650 7.4V Li - ion battery pack is widely used in cordless power tools. For example, in cordless drills, the high - voltage output provides sufficient power to drive the drill bit through various materials. The battery pack's energy density allows the drill to operate for a reasonable amount of time before needing to be recharged. It also enables quick acceleration and high - torque performance, making it suitable for tasks such as drilling into wood, metal, or masonry.
In impact drivers, the 7.4V battery pack can supply the necessary power for high - impact applications. The consistent voltage output helps to maintain a stable impact force, which is crucial for driving screws quickly and efficiently into different surfaces.
Portable Electronics
Some high - performance portable audio devices, such as high - power Bluetooth speakers, use 18650 7.4V Li - ion battery packs. The voltage and capacity of the battery pack can support the amplification and playback of high - fidelity audio for an extended period. The relatively high voltage is beneficial for power - hungry audio components, ensuring clear and loud sound output.
It is also applicable in certain portable gaming consoles. The battery pack provides the energy required to run graphics - intensive games and power the console's display and other components for a longer gaming session without the need for frequent recharging.
