## Safety Notice

* Use only the DeltaQuad Dual Battery Charger to charge the DeltaQuad Evo Li-ion battery. Do not use a NiCd or NiMH charger. Failure to follow this guidance may result in a fire, which could cause personal injury or property damage. DeltaQuad assumes no responsibility or liability for damages resulting from the use of third-party chargers.

* Charge the batteries only at ambient temperatures between **5°C and 30°C** (41°F and 86°F).
* Never charge batteries unattended unless you are using a Battery Safe. When charging Li-ion batteries, always remain in constant observation to monitor the process and respond to any potential issues.
* Ensure the battery is charged under supervision and away from flammable materials or surfaces.
* Disconnect the battery from the charger once it is fully charged.
* Do not use a damaged charger.
* If you notice a battery starting to balloon or swell, discontinue the charging process immediately. Disconnect the battery and dispose of it safely. Continuing to charge a swollen battery can result in a fire. Similarly, never use a battery that is swollen or ballooned.
* Since delayed chemical reactions can occur, it is best to observe the battery as a safety precaution. Battery observation should take place in a safe area outside of any building or vehicle and away from combustible materials.
* Wire lead shorts can cause a fire! If you accidentally short the wires, place the battery in a safe area for observation for approximately 1 hour. Additionally, if a short occurs and makes contact with metal (such as rings on your hand), severe injuries may result due to electrical conductivity.
* A battery can still ignite even after 1 hour. A battery that emits a hissing sound is almost certain to ignite. Prioritize your safety and that of your surroundings before taking any action.
* In the event of a crash, wait 10 minutes to ensure the battery was not compromised before removing and safely disposing of it.
* Do not use a battery that has been involved in a crash or sustained any significant impact.
* Do not expose the batteries to water. If a battery pack is exposed to water, replace it immediately.

{% hint style="info" %}
Only place the battery in the vehicle before the flight, and remove it immediately after the flight. Always transport the battery in the dedicated compartment of the flight case or a safe transportation unit, such as a fireproof bag or storage container.
