4.2 Initial Charge

US-1 does away with replaceable battery packs by integrating the
battery with the airframe structure. US-1 is shipped 30% charged.
Before use, charge US-1 to 100% by following the charging proce-
dure outlined in Section 5.
4.3 First Preflight
A first preflight with US-1 should performed as specified in Section
6. Note that if the vehicle is being deployed more than 50 miles
from Santa Clara, where it was factory calibrated, it will require a
compass calibration as outlined in 6.6.

5.1 Charging Safety

Charging US-1 with damaged or improper equipment can result in
a fire. Before charging US-1, ensure that the charger, charge con-
nector, and vehicle are undamaged and unmodified. Do not charge
US-1 if the vehicle has suffered crash damage. Do not charge US-1
with any charger other than the one provided. Remove any non-
standard payloads before charging US-1.
A grounded outlet is required to reduce the risk of electric shock.
Do not use ground adapters or modify the charge plug in any way.
Only one charger may be operated on a single 15 amp household
circuit at a time.
The charger may become hot during charging. Provide at least
1" clearance on all sides of the charger and aircraft during active
charging and use hand protection to safely handle the charger dur-
ing or immediately after operation. Do not charge US-1 inside of
the hard-shell carrying case.
