5.2 Charging US-1
US-1 can be safely charged when the battery cells are between 32
F and 104 F. Should the cells be too cold or too warm, the charger
will turn off. The vehicle will resume charging onche cells are within
the above temperature range.
At the 25A standard charge rate, US-1 will charge from 0% to
75% in 91 minutes and from 0% to 100% in 144 minutes.
To charge US-1:
1. Plug the charger into a standard wall outlet. The blue power
icon on the charger will light up, indicating the charger is on.
2. Locate the magnetic charging ports on the side of US-1.
3. Connect the round magnetic plug from the charger to the un-
covered port. It will snap into place once the magnets are
aligned. Once connected, the LEDs on US-1 will turn purple.
4. During charging, the LEDs on the drone will flash purple. The
orange lighting bolt icon on the charger will illuminate, indi-
cating the charger is active.
5. The battery charge indicator on the charger will indicate the
state of charge of the US-1.
(a) If the bottom LED is blinking green, the vehicle is less
than 80% charged.
(b) If the bottom LED is solid and the top is blinking green,
the vehicle is between 80% charged and full.
(c) If both LEDs are solid, the vehicle is fully charged. In
addition, the LEDs on the drone will turn green and the
orange ligning bolt on the charger will turn off, indicating
the charger is no longer active.
If the yellow triangle on the charger continues to blink after charging
begins, there is an error. Please refer to the troubleshooting section
of this handbook.
