Charging is an important step in using rechargeable batteries. Proper and reasonable charging is good for extending battery life, while improper charging will have a great impact on battery life. Lithium batteries are basically packaged separately according to each product and are not universal. Therefore, each product also provides its own charging equipment, which is not universal. You only need to follow their respective instructions when using them.
1. Shell (metal, plastic or open type)
2. Input and output
3. Flexible circuit boards, electronic components (capacitors, CPUs, microcontrollers, MOS tubes, triodes, switch tubes)
