  The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method.

 . Replace the battery
  You can change the battery in the LSPH01.The type of battery is not limited as long as the output is between 3v to 3.6v.  On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
