Cautions for Power Supply with 3.7V Lithium Battery
1. When powered by batteries, the battery voltage is less than 3.3V decoder board automatically shuts down. After re-energizing or full charging, the contacts are switched on/off for 2 seconds.
2. When using batteries for power supply, if the voltage of batteries is too low, there may be ""nourishing"" noise. In this case, the batteries need to be charged.
3. Because there is no charge protection circuit for lithium batteries on decoder board, it is recommended to use lithium batteries with protection board.
4. If your rechargeable battery supports Micro USB charging directly, you can use Micro USB charging directly to the battery.
