Application:
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.
Electric Vehicles and Toys
In small - scale electric vehicles such as electric scooters for kids or small electric bikes, the 18650 7.4V Li - ion battery pack can be used as a power source. It provides enough energy to drive the vehicle at a reasonable speed and for a certain distance. The voltage is suitable for powering the motor and other electronic components such as lights and brakes.
For remote - controlled (RC) toys like RC cars and RC airplanes, the 7.4V battery pack can supply the power for high - speed running or flying. The energy and voltage characteristics enable the toys to perform well - powered maneuvers and have a longer playtime between recharges.
