2. When using a battery to supply power, if the battery voltage is too low, a "sizzling" noise may appear. In this case, the battery needs to be charged.
3. Since there is no lithium battery charging protection circuit on the decoder board, it is recommended to use a lithium battery with a protection board.
4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to directly charge the battery.
5. The power supply must be greater than 10W. It is recommended to use a power supply above 20W. If the power supply is not enough, the sound quality will be affected.
