1. Battery: The receiver has a built-in 6800mAh/7.4V battery.
2. Charger: To charge the receiver, use the standard charger. When it is in charge, the power button
light will turn red.
Notice:
If the battery needs to be stored for a long time, it should be charged to about 70%
and then placed in a dry, low temperature environment. It is recommended that you
charge and discharge the battery every 3 months. If you do not have the conditions
that are needed for charging and discharging, take out the battery after 3 months and
charge it to about 70% before storing it once more.
