The battery should be supervised when charging, and the charger should be unplugged as soon as possible after charging is completed to avoid battery overcharge.
6. After use, the main power switch should be turned off. When the device is not used for a long time, keep the battery voltage at about 7V, remove the bottom battery compartment, unplug the battery cable, take out the lithium battery pack and put it in the battery safety area. Do not mix with metal objects, and the insulating film wrapped outside cannot be torn off.
