Notes for use of 3.7v lithium battery power supply
1. When using the battery power supply, the battery voltage is lower than 3.3v and the decoder board automatically shuts down. After recharging or fully charging, switch on/off contact for 2 seconds.
2. When using the battery power supply, if the battery voltage is too low, there may be "sizzling" noise, in this case, the battery needs to be charged.
3. Since no lithium battery charging protection circuit is designed on the decoding board, lithium battery with its own protection board is recommended.
4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to directly charge the battery.
