Is USB charging better for the battery?
The computer USB can directly charge the battery, which is theoretically possible.But in practical applications, you must pay attention and solve the following problems:
1. The battery parameters should be suitable
The USB output voltage and current should be roughly the same as the rated voltage and current of the battery. If the battery voltage is higher than the output voltage of the USB, the USB will not be able to charge the battery.
2. Determine the battery positive and negative pole
The positive and negative poles of the battery must be consistent with the positive and negative electrodes of USB, otherwise it may cause damage to the battery.
3. The joint should be firm
The connection between the battery and the USB plug should be handled well, and it is best to use a universal plate for welding.
