When using battery power, the deer board will automatically shut down when the battery voltage is lower than 3.3V, and then short-circuit the on/off contact for 2 seconds to switch on after re-powering or fully charging.2. When using a battery to supply power, if the battery voltage is too low, a ''sizzling'' noise may appear. In this case, the battery needs to be charged.3. Since there is no lithium battery charging protection circuit on the deer 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 directly charge the battery.Remote control without batteries.
