Precautions for using 3.7V lithium battery

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.
