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.
Medical Devices
Some portable medical monitoring devices, like portable electrocardiogram (ECG) machines, utilize 18650 7.4V Li - ion battery packs. The consistent voltage supply is essential for accurate and reliable operation of the medical sensors and electronics. The battery pack's capacity enables the device to function for a significant period during patient monitoring, whether in a clinical setting or during home - care visits.
In portable oxygen concentrators, the 7.4V battery pack provides the power needed to separate oxygen from the air and supply it to the patient. The battery's energy density allows the concentrator to operate for a reasonable amount of time, giving the patient more mobility and freedom to move around.
