• If the remaining charge of a battery is lower than 7%, the battery cannot charge
the external device.
Accumulating Power
1. Insert more than one battery into the charging hub, and press and hold the function
button until the status LED turns green. The status LED of the charging hub pulses
green, and the charge is transferred from the battery with the lowest power level to
the battery with the highest power level.
2. To stop accumulating power, press and hold the function button until the status LED
turns yellow. After stopping power accumulation, press the function button to check
the power level of the batteries.
• Power accumulation stops automatically in the following situations:
◆
The receiving battery is fully charged, or the power of the output battery is
lower than 5%.
◆
A charger or external device is connected to the charging hub or any battery
is inserted or withdrawn from the charging hub during power accumulation.
◆
Power accumulation is interrupted for more than 15 minutes due to
abnormal battery temperature.
• After accumulating power, charge the battery with the lowest power level as
soon as possible to avoid discharge.
