Robot Charging and Battery Precautions
1. Low-Battery Threshold Alarm
- When the battery level drops below the threshold (10.2V), the buzzer will emit a beeping alarm (beep—beep—beep). At this time, you should charge the battery with the charger. Click the button on the right to switch to the BATTREY_INFO panel to view the current voltage and the voltage threshold.

2. Charging the Battery
- Plug the charger included with the product into the power outlet; the charger indicator lights up green

- Turn off the robot's power and connect the charger plug to the charging port on the control board

- During charging, the charger indicator is red; after the battery is fully charged, the indicator turns green

Specifications for Using the Lithium Battery Pack and Charger
- Strictly forbid connecting devices that exceed the load limit of the product.
- Never use batteries or chargers other than those officially provided by Yabo.
- When the battery level is low, the buzzer on the development board sounds a "beep-beep-beep" alarm. At this time, turn off the power and then charge the battery.
- When charging the battery, turn off the main power switch on the development board. Do not use the battery while it is being charged, to prevent the charger or battery from exploding.
- During charging, when the charger indicator is blue, the battery is charging; when the charger indicator is green, the battery is fully charged. The battery should be supervised by someone while charging. After charging is complete, unplug the charger as soon as possible to avoid overcharging the battery.
- After use, turn off the main power switch. When the device will not be used for a long time, keep the battery voltage between 10.2V-12.6V, remove the lithium battery pack from the bottom, and place it in a safe battery area. Do not store it together with metal objects, and do not tear off the insulating film wrapped on the outside.
- Keep away from heat sources, open flames, and any liquids. Never use it in humid conditions or in the rain. A humid environment may cause a short circuit and damage the product.
- If the lithium battery pack or battery charger emits smoke or becomes hot (in severe cases the outer packaging may crack), quickly disconnect the power strip or switch off the main circuit breaker, then promptly unplug the charger, remove the battery, and place it in an open area.
- If the lithium battery pack or battery charger catches fire or emits smoke, extinguish the fire with sand or a dry powder fire extinguisher, and then quickly evacuate to a safe area.
- Do not use the lithium battery pack or battery charger if it is damaged, leaking, excessively hot, deformed, discolored, has an unusual odor, or shows any other abnormal signs. Contact Yabo or another agent for handling in a timely manner.
