A printed circuit board (PCB) is used to protect 7.4V 18650 batteries from potential hazards. The PCB acts as a safeguard to control the flow of electric current, protect the battery from overcharging, and ensure efficient charging and discharging. The PCB also balances the voltage across each cell in the battery pack, preventing any one cell from being overcharged or overdischarged.

Applications of 7.4V 18650 with PCB

Flashlights and Headlamps

    Flashlights and headlamps are common applications for 7.4V 18650 batteries. These devices require a reliable and long-lasting power source that can withstand harsh conditions. With the addition of PCB protection, the battery is safe from short-circuiting or overheating, making it a trustworthy choice for outdoor activities.

Medical Devices

    Medical devices such as insulin pumps and portable oxygen concentrators often use 7.4V 18650 batteries with PCB protection. These devices require dependable power sources to ensure that they operate safely and effectively. The PCB also ensures that the battery is charged and discharged correctly, prolonging the life of the battery and reducing the need for frequent replacements.

Robotics

    Robots often use 7.4V 18650 batteries with PCB protection because of their compact size and high energy density. The PCB ensures that the batteries are charged and discharged evenly, maximizing battery life and minimizing the risk of damage to the robot's electronic components.

Drones

    Drones require lightweight and high-capacity batteries to achieve maximum flight time. Many drone manufacturers use 7.4V 18650 batteries with PCB protection due to their high energy density and long cycle life. The PCB ensures that the batteries are safe to use and prevents any damage to the drone's electronic components.

POS

    Point-of-sale (POS) systems have become an integral part of modern retail businesses. These systems enable businesses to process transactions and manage inventory quickly and efficiently. However, these systems require a reliable source of power to function properly

Speaker

    Bluetooth speakers have changed the way listening music. with bluetooth technology, we are not limited to a music source with cables or cords, we are now able to connect to the speaker wirelessly and enjoy high quality sound without the issue.
