Lithium Battery Usage Precautions
- When using battery power, the decoding board automatically shuts down when battery voltage drops below 3.3V. Requires power cycle or full charge, then short circuit the on/off contact for 2 seconds to resume normal operation.
- When battery voltage is too low, "Zizi" noise may occur. In this case, the battery needs charging.
- No lithium battery charging protection circuit is designed on the decoding board. Recommended to use lithium batteries with built-in protection boards.
- If your charging battery supports micro USB direct charging, you can use micro USB to charge the battery directly.
- Power supply must be more than 10W. Recommended to use power supply of more than 20W. Insufficient power supply will affect sound quality.
