## Safety Warnings <a href="#safety-warnings" id="safety-warnings"></a>

{% hint style="danger" %}

* Due to the regenerative braking, the KISS ESC should only be powered by LiPo batteries. A power supply might get damage when braking. The ESC takes care of itself.
* Never start a brushless motor in your hands!
* While starting up with propellers mounted, always do it in a distance of yourself & objects
* The KISS ESC can be locally heated up to 80 ° C during operation!
* While soldering do not connect a voltage source at the ESC / speed controller.
* Some components on the KISS ESC can be destroyed by static charge. When handling such electronics, make sure to be grounded.
