TVX machines can use lithium batteries, but it is not recommended. Because there is no signal communication between the controller and the lithium battery, the power display of the machine is inaccurate. Under normal circumstances, the TVX machine will alarm when the battery is low, and at the same time, the brush disc will automatically lift up and stop working. Only the drive motor can still run for the customer to drive the machine back to charge, but suddenly the whole machine is powered off during use, and then you can only manually release the battery valve and return the machine to charge.
