Connect the power adapter or a 3S~6S battery to this port to charge the built-in battery. If use a
3S~6S battery, the ground end comes with the protection function, which prevents the 3S~6S batter
from over discharge. When the ground unit is connected with the external power adapter or battery,
the built-in battery disables itself and switch to external power source. Beware of the input voltage
range, do not exceed the operating range (11~26V).
