Flight Battery; Controller - 3DR Solo User Manual

4.9.5 Motor Shutoff
In the event that Solo's motors do not stop after landing or for an emergency in-flight kill switch, Solo includes
an emergency motor shutoff procedure. To shut off the motors at any time, either in flight or on the ground, hold
the A, B, and Pause buttons at the same time. An initial screen will appear on the controller to confirm the shutoff
command; continue to hold A, B, and Pause buttons to activate motor shutoff. Use the emergency motor shutoff

only as a last resort.

4.10 Flight Battery

Use caution when handling the Solo Smart Battery; lithium polymer batteries can cause a fire if handled incorrectly.
Never alter, puncture, throw, bend, or impact the battery. Keep the battery away from liquids, fire, microwaves, and
other hazardous or combustible materials. Don't expose the battery to extreme temperatures. If the battery is hot to
the touch, wait for it to cool before using or charging.
Inspect the battery before and after each flight. It is possible for the battery to be damaged in shipping, use or
charging. If you notice any abnormal features such as damage to the exterior shell, swelling, deformation of the
battery, abnormal smell, leakage, or other unexpected behavior, do not use the battery! These can be signs of
serious damage that can cause the battery to catch fire. To prevent a hazard in case of fire or explosion, disconnect
the battery, and place the battery in a safe area outside of any buildings or vehicles and away from flammable
materials. Do not dispose of the battery in the trash; bring it to a battery recycling center as soon as possible. In the
US and Canada, visit call2recycle.org to find a location.
For long-term storage, store the battery in an 64° F (18° C) to 82° (28° C) F environment, between 45-85%
relative humidity and with 50% charge. Always store the battery in a place where it won't be exposed to extreme
temperatures or direct sunlight.

4.11 Controller

The controller's rechargeable lithium ion (Li-ion) battery is housed inside the controller, accessible by the battery
door on the back of the controller. The controller battery is pre-attached to the controller, and shouldn't be
disconnected unless:
• You plan to store the controller for over three months without using it. In this case, disconnect the battery
from the controller and leave the battery inside the controller to store it.
• You need to replace or upgrade the controller battery. Upgraded controller batteries with double the
capacity are available from store.3dr.com or an authorized retailer. In the case where you need to store the
extra controller battery, store it in a location where it will not come into contact with metal objects or other
batteries. If the battery's connector comes into contact with a metal object, it can short circuit the battery and
cause a fire.
Keep the controller away from liquids, fire, microwaves, and other hazardous or combustible materials. Don't
expose the controller to extreme temperatures. If the controller is hot to the touch, wait for it to cool before using
or charging. Perform periodic visual inspections of the controller battery to check for any damage, and handle the
controller battery using the same safety precautions as the flight battery.
