Fixed! Xhorse Dolphin XP005 Cutter Restore Automatically?

Dolphin XP005 cutter restore automatically when it touches the key blade, how to fix it?
Dolphin XP005, the probe works well, but the cutter will restore itself once it touches the key blade. Have done the electrical conductivity test: X- and Y-axiz are normal, but the main axiz has something wrong.

The problem is a dysfunctional battery.
The machine disconnects and the probe & the cutter restore because it is powered down and reboot automatically.

Contact us and attach its serial number to check the warrenty firstly.
Need a new battery to replace the broken one.
