Cautions when using 3.7V lithium battery 1. When the battery is used for power supply, the decoding board will automatically shut down when the battery voltage is lower than 3.3V. After the power is turned on or fully charged, the on / off contact is shorted for 2 seconds to start up. 2. When using battery power, if the battery voltage is too low, "Zizi" noise may appear. In this case, the battery needs to be charged. 3. As the lithium battery charging protection circuit is not designed on the decoder board, it is recommended to use the lithium battery with its own protection board. 4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to charge the battery directly.
