This section provides detailed instructions on how to properly charge the B2-W robot's battery and its remote control to ensure safe and efficient power management. It explains the step-by-step battery removal and charging process, highlights the importance of using compatible AC power sources, and outlines safety precautions such as ensuring the battery is off and cooled before charging. Charging indicators are explained clearly to help users monitor battery levels. Additionally, guidance is included for charging the companion remote control using a 5V/2A USB charger, with visual cues provided by LED indicators to signal the charging status. Proper charging procedures are critical to maintaining battery health and preventing equipment damage.

1. How to Charge

Due to factors such as battery self-discharge during transportation and storage, it is normal for the battery to have low or no power when first used. You can charge it as follows.

a. Charge the battery

1. Remove the battery

   • Remove the battery from the B2-W body (Pull out the battery pack strap)

   

1. Charger input AC power (100 - 240V, 50/60 Hz)

   • Connect the charger to an AC power source (100-240V, 50/60Hz).
   • It must be ensured that the external power supply voltage matches the rated input voltage of the charger before connecting.
   • Otherwise, the charger will be damaged (the rated input voltage of the charger is marked on the nameplate of the charger).

   

1. Connect the B2-W battery

   • Plug in the input AC power first before charging the battery, then connect the charger to the battery.
   • Before charging the battery, ensure that the battery pack is switched off. Otherwise, the battery and charger may be damaged.
   • The users need to remove the battery pack from the robot itself when charging the battery pack.

   

1. Manually disconnect the power when fully charged.

   • In the charging state, the battery indicator of battery pack will flash at a frequency of 1Hz (1 second/time) and indicate the current battery.
   • If the battery indicator is off, the battery pack is fully charged. Please remove the battery pack and charger to finish charging.

   

1. After the robot completes operation, the battery pack may reach elevated temperatures. Must cool the battery pack to room temperature before recharging to prevent thermal damage.

2. Remote Control Charging

When the battery indicator light of the companion remote control shows that the battery is low, you should connect the companion remote control as shown in the figure below:

1. We recommend you use a 5V/2A USB charger which meets FCC/CE standard.
2. Ensure that handheld remote control is switched off before charging it.
3. The power indicator light will flash at 1Hz (1 second/time) in charging status and indicate the current power level.
