Matters needing attention when using 3.7V lithium battery: 1. When using battery power, the decoder board automatically shuts down when the battery voltage is lower than 3.3V. It needs to be re-powered or fully charged to short-circuit the on/off contact for 2 seconds to work properly. 2. When using battery power, if the battery voltage is too low, there may be "sizzling" noise. 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 charge the battery directly. 5. The power of the power supply must be greater 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.
