• When the battery is used for power supply, if the voltage of the battery is too low,"Zizi" noise may appear, in this case, the battery needs to be charged
• Since there is no lithium battery charging protection circuit designed on the decoding board. it is recommended to use the lithium battery with its own protection board
•  If your charging battery supports micro USB direct charging, you can use micro USBto charge the battery directly
•  The power supply must be more than 10W. It is recommended to use a power supply of more than 20W. If the power supply is not enough, the sound quality will be affected.
