If your Xhorse Dolphin XP005/XP005L key cutting machine failed to charge the battery, or Bluetooth connection disconnected during key cutting procedure, first of all do a battery test.
When checking the battery information, both the battery cells and the BMS (Battery Management System) board appear to be functioning properly. This suggests the issue may be related to the resistor on the green BMS board.
Disassemble the battery module and remove the green BMS board.
Replace the 5mΩ battery sampling resistor shown in the picture below with a 2512 package 2mΩ resistor (1W power rating).
Then try again.
